Telog Instruments the leading supplier of remote monitoring systems to the water markets, and Wallingford Software Limited, the leading developer of hydraulic modeling software for the water industry, have agreed to collaborate on the development of a real-time, networked water modeling application.

The application solution combines Telog’s Enterprise data acquisition system with Wallingford Software’s InfoWorks modeling software application to provide calibrated, real-time website hosted information on environment water events and forecast management. This will allow users and emergency response teams to more accurately deploy resources during storm events.

The development agreement, signed during WEFTEC ‘07 in San Diego, will create an automatic data exchange interface between the companies’ application servers over a common data network, including the Internet. Telog’s Enterprise will source remote site information on collection system flows and overflows, rainfall, and surface water levels to InfoWorks software to enable real-time calibration of the model. User’s can then view the effects of a wet-weather event on river levels, wastewater collection and storm water systems as weather events occur with real time forecasting and warnings.

Tom Davies, President of Wallingford Software, stated: “real-time modeling and forecasting using remote data calibration available to users via the web is a key step towards achieving a more effective response to extreme weather events.”

Telog’s President Barry Ceci commented: “this is a great example of two market leading products that when combined create an important new application solution that was not technically achievable independently.”

Tom Davies stated that the InfoWorks real-time model application with the integrated Telog remote data interface would be available for demonstration during the first quarter of next year.

Wallingford Software announces today the release of FloodWorks v8.5, the leading real time flood forecasting and warning software solution. A modular software package, FloodWorks is used extensively for the real-time simulation and forecasting of extreme hydrological and hydraulic conditions within river basins, drainage systems and the coastal zone. With version 8.5 Wallingford Software has overhauled the software’s user interface, improving usability and thereby enabling more effective flood forecast management.

FloodWorks 8.5 features a much-improved graphical user interface for the FloodWorks Event Manager. “This will improve ease and efficiency of use, extend the ability of individual users to customise their own displays and enhance the visibility of the forecast results”, says Product Manager, Tyrone Parkinson.

Significant improvements have been made to both the user graphs and map graphs to provide more flexibility to control the number of traces on each graph, the line colour and style used by each graph, range limits and the display of event thresholds. These improvements can be utilized both in FloodWorks Configuration Manager, when setting up default graphs for all users, or by individual users working on an operational system via FloodWorks Event Manager.

Once a particular user has configured their preferred arrangement and map styles, tables and graphs, these can now be saved as Workspaces that can be instantly re-opened, without having to repeat the customization process.

A further development relates to ’site’ functionality, which has now been extended to include both polylines and polygons. In previous versions of FloodWorks, sites (and any events or alarms raised at a site) were only associated with points. This was highly appropriate for individual locations, such as defence low spots or individual gauge locations but insufficiently accurate when used to identify critical conditions either along a reach of watercourse or within a sub-catchment or floodplain area. “The inclusion of polylines and polygons as options for defining a site now allows users to represent reaches and areas more clearly”, believes Tyrone Parkinson. “These points, lines and polygons can now also be colour coded according to either the current Event or Status Object condition.”

Since its launch in 2000 FloodWorks has become recognised as the most advanced real time flood forecasting application in the world with users across the world, particularly in Europe and South East Asia.

UV disinfection systems from Hanovia can now be successfully incorporated into a number of meat processing applications including brine chillers, meat marinade and pickle injectors, air handling systems for meat packing plants, and the treatment of plant wastewater for reuse or safe discharge.

Compact UV systems can be installed on recirculating brine chillers and meat pickle and marinade injectors to destroy pathogenic microorganisms like Listeria and E. coli. Depending on the model, some UV systems can operate very effectively through a wide range of temperatures and applications - from super-cooled brines to very hot sanitation cycles. Multi-lamp, medium pressure UV systems in particular ensure thorough disinfection of viscous, low-transmission fluids.

Designed to meet the stringent sanitary requirements of the food industry, the microprocessor controlled UV units can be easily integrated into plant control systems. Maintenance requirements are minimal - typically the UV lamps only need replacing once a year, an easy operation which can be carried out by on-site personnel. Automatic internal wipers keep the UV lamps clean, ensuring optimum UV output at all times - especially important in solutions with a high concentration of suspended solids.

The benefits of UV technology in brine chiller and pickle or marinade processes are remarkable. Risk of contamination are greatly reduced while shelf life is increased. Additionally, in marinade applications, operating costs are reduced through less frequent fluid change-over.

In ready-to-eat packaging areas, Hanovia’s UV air treatment systems can be used to disinfect incoming air. Installed within existing ductwork, a single high-powered lamp can disinfect up to 140m³/minute of air. By destroying harmful microorganisms in the heating, ventilation and air conditioning systems, the risk of spoilage and contamination from airborne pathogens is minimised.

The final application of UV in meat processing operations is as a non-chemical treatment for plant wastewater. Increasingly, meat processors are caught between conflicting sets of regulations - while food hygiene regulations in many countries require increased use of water to rinse carcasses, environmental regulations are limiting the amount of fresh water that a plant can consume. With only so much fresh water coming in, plants are forced to reduce capacity in order to meet these conflicting requirements.

By reusing disinfected wastewater in non-contact applications like chillers and cooling towers, more fresh water can be devoted to processing. Hanovia’s UV systems can be used in conjunction with other waste treatment processes to disinfect wastewater without chemicals, making it fit to use again. By using this low-maintenance technology, plant production capacity can be increased and hazardous chemicals are eliminated.

Based in the United Kingdom, Hanovia is a world leader in UV disinfection technology for processing applications. The company has over 80 years’ experience in the design, development, manufacture and distribution of UV systems worldwide.

Latest release of InfoWorks (v8.5) signals major product expansion

Wallingford Software, the leading developer of hydraulic modeling software for the water industry, has announced the immediate availability of a completely new InfoWorks product, InfoWorks Storm Drainage (SD). Also launched simultaneously with the release of InfoWorks v8.5 is a completely new and fully integrated module, InfoWorks 2D.

This module is available for InfoWorks CS v8.5, InfoWorks SD v8.5 and InfoWorks RS v9.0. Other important developments announced today include the availability of Unidirectional Flushing as a core function within InfoWorks WS.

InfoWorks 2D delivers fast, accurate and detailed surface flood modeling and is ideally suited to modeling flows through complex geometries such as urban streets and buildings, road intersections and other transport infrastructure, and open ground where either source or direction of flow is problematic to assume. Full integration with Wallingford Software’s 1D solutions simplifies the model construction and optimizes users’ productivity. By using 1D simulation to identify where flooding happens, and then using the combined 1D and 2D simulation to investigate the direction and depth of flood flows in these smaller areas, users can achieve a cost-effective balance between model-building time and simulation accuracy.

“Some existing solutions assume that a 2D model of the whole study area has to be built,” says Sales and Marketing Director, Paul Banfield. “With InfoWorks 2D, smaller detailed 2D models can be created within a single 1D model dramatically reducing the model size - minimizing the time spent building and simulating these models.”

InfoWorks SD is a fully dynamic, hydraulic modeling solution developed to meet the most demanding requirements of stormwater professionals. Every frequently encountered stormwater hydraulic structure can be modelled in InfoWorks SD, including inlet capture and bypass, gravity and pressure piping, pumps and their control systems, detention ponds, outlet structures, open channels, culverts, and overland flow paths. InfoWorks SD also models BMP design, construction and maintenance practices and criteria for stormwater facilities, and simulates control structures as well as the associated programmable logic controllers (using an InfoWorks Real Time Control scenario).

“Modeling stormwater runoff accurately means being able to model stormwater flows in the complex real-world environment that features a wide range of both underground and overland structures and potential flow paths,” explains Paul Banfield. “InfoWorks SD achieves this to exceptional standards without compromising either usability or performance to give users the most flexible and productive stormwater drainage solution available today.”

“Wallingford Software issues two major product releases each year, a rigorous schedule unmatched in the entire water industry worldwide. In addition to the launch of two new InfoWorks solutions, InfoWorks v8.5 includes a range of improvements and enhancements to the core solutions.

Amongst these for InfoWorks WS is a new and advanced Unidirectional Flushing tool and a new upstream and downstream trace tool that can also be used for water source analysis and pressure zone design. InfoWorks CS features a number of important performance improvements and a new search option has been added to InfoWorks RS.

As with every release of InfoWorks, many improvements apply to all InfoWorks solutions. With v8.5 these focus primarily on further improvements to data integration with other modeling packages, CAD and Oracle databases.

“This is our single largest product announcement since the launch of InfoWorks,” said Wallingford Software Sales Director Paul Banfield. “It demonstrates our clear understanding of the issues dominating the industry today and our complete commitment to meeting the needs of the worldwide water industry.”

As global concern over drinking water safety and security grows, new technologies are sought to provide early warning on dangerous changes in water quality. For the first time CheckLight will be presenting its new technology at the WATEC exhibition - technology which enables rapid detection of broad range of dangerous contaminations in drinking water.

This new technology, to be embedded in CheckLight’s latest versions of the ToxScreen and AOC test kits enables the user to carry out monitoring activities much easier, faster and at a higher sensitivity than ever before. Using this technology water utilities and supervising organizations can much better protect public health.

WATEC - the international “h20 Technologies & Environmental Control” exhibition & conference will be held in Tel Aviv between October 30th and November 1st, 2007. At the exhibition CheckLight will be presenting its vision and latest technological developments while in a parallel venue CheckLight is a contributing member at the “International Workshop on h20 Security”.

The purpose of the meeting will be to advance on international standards for water security issues, resulting at an International Workshop Agreement (IWA), to be published by ISO, under the title “Framework of h20 Security Fundamentals”.

Hanovia UV technology has been selected by NZ Hothouse, a leading New Zealand provider of fresh produce, to disinfect the water used for soil-less plant cultivation in its glasshouses.

Located near Auckland, NZ Hothouse has almost 20 hectares of glasshouses on two sites growing tomatoes, capsicums and cucumbers for distribution both nationally and internationally.

The source of the water is a combination of rain water and borehole water, which is stored in large outside holding ponds. The main microbial challenge organisms in the water include fungi such as Pythium, Phytophthora and Fusarium; bacteria such as Clavibacter and viruses such as tomato bronze (wilt) virus and tomato mosaic virus.

No conventional microbiological checks are carried out, but NZ Hothouse uses what it calls ‘bait tests’ with very young plants to see if they fall victim to any of these water-borne pathogens.

Two Hanovia PMD200 medium pressure systems are installed - one for each site - treating up to 68 m³ water per hour. UV treatment is ideal for this application as it is a completely clean technology that introduces no chemicals or unwanted disinfection by-products into the water and does not alter its pH.

The UV systems feature an automatic wiper which prevents the build-up of deposits on the quartz tube, ensuring optimum UV dose at all times. Photon control panels provide the operators with data on flow rate, UV dose and intensity and can log up to one year’s performance data, which is downloadable to a PC via an RS323 port. The control panel can also be operated remotely, allowing the system to run 24 hours a day. Maintenance of the unit is restricted to the replacement of a lamp every six months, a simple operation that can be carried out by on-site staff.

All Hanovia UV disinfection systems are easy to install, with minimum disruption to the plant. They need very little maintenance, the only requirement being replacement of the UV lamps and servicing of the wiper systems every 12 months, depending on use.

UV disinfection specialist Hanovia Limited has appointed Andrew Clark as its new Technical Director. Andrew will be responsible for developing Hanovia’s UV expertise in process water applications such as pharmaceutical and electronics manufacturing, food and beverage processing, brewing and swimming pools worldwide.

He joins Hanovia from Hozelock Limited where he was Director of Design. Prior to that appointment he was Technical Manager of Raymarine Limited. Andrew, who is a graduate of the University of Southampton in the United Kingdom, has considerable experience in project management and designing products for global markets against tight unit cost constraints.

Commenting on his appointment Andrew said, “With many exciting developments under way I am greatly looking forward to being part of Hanovia’s continuing growth. With our strong scientific knowledge base we are exceptionally well placed to expand use of our chemical free, UV water treatment technology.”

Based in the United Kingdom, Hanovia is a world leader in UV disinfection technology for process water and swimming pool applications. The company has over 80 years’ experience in the design, development, manufacture and distribution of UV systems worldwide.

To protect fish farms and hatcheries from outbreaks of water-borne diseases, water treatment specialist Hanovia Limited has developed a high intensity UV disinfection system. Capable of treating up to 700m³/hr of both fresh or sea water with at least a 99.99% kill rate, the UV system can be used to treat both incoming and recirculation water, allowing flexibility in the choice of site and a rapid payback for farmers.

Increased water extraction and lowered water quality can result in increased outbreaks of viral and bacterial fish diseases. Due to the intensive nature of fish farming, fish stock is also highly susceptible to infection from natural fish populations in the water feeding the farm. To break the infection cycle between fish farms and natural fish populations, a disinfection system is needed to treat water entering and circulating within fish farms.

UV is ideally suited for these applications as it uses no chemicals and does not create by-products which would harm the fish stock, or other aquatic life, on discharge. Unlike other treatment methods, UV avoids the expense of complex monitoring systems involved in adding and removing chemicals before the water reaches the fish.

In addition, it does not alter the pH of the water. Indeed, UV is the most economical disinfection technique that can be used in fish aquaculture. Applications include treatment of water in hatcheries, shell-fish purging tanks and fry rearing tanks, and recirculation water in marine parks and aquaria.

Maintenance of the system is restricted to the replacement of the UV lamp every 12 months, a simple operation that can be carried out by on-site staff. An automatic or manual wiper can be fitted over the quartz sleeve which surrounds the UV lamp to prevent the build-up of any deposits, ensuring maximum levels of irradiation at all times.

A significant feature of the Hanovia system is the new Photon control panel which displays a range of useful functions such as flow rate, UV dose and intensity. It is capable of logging up to one year’s performance data, which can be downloaded to a PC through an RS232 port. Linked into a central computer, the control panel can also be operated remotely, and allows the system to operate around the clock.

To date Hanovia has installed over 300 aquaculture systems in 14 countries around the world. Applications include water treatment in hatcheries, fish farms (salmon, sea bream and sea bass) shellfish depuration tanks and fry rearing tanks as well as treating re-circulation water in marine parks and aquaria.

Outstanding stormwater modeling software with multiple unique user benefits.

Wallingford Software, the leading developer of hydraulic modeling software for the water industry, has announced the forthcoming release of InfoWorks SD (Storm Drainage) for the fast, accurate and comprehensive modeling of stormwater flows. An important new addition to the InfoWorks family of modeling software, InfoWorks SD is a fully dynamic, hydraulic modeling solution developed to meet the most demanding requirements of stormwater professionals.

“Modeling stormwater runoff accurately means being able to model stormwater flows in the complex real-world environment that features a wide range of both underground and overland structures and potential flow paths”, explains Sales and Marketing Director Paul Banfield. “InfoWorks SD achieves this to exceptional standards without compromising either usability or performance to give users the most flexible and productive stormwater drainage solution available today.”

Every frequently encountered stormwater hydraulic structure can be modelled in InfoWorks SD, including inlet capture and bypass, gravity and pressure piping, pumps and their control systems, detention ponds, outlet structures, open channels, culverts and overland flow paths. InfoWorks SD also models BMP design, construction and maintenance practices and criteria for stormwater facilities, and simulates control structures as well as the associated programmable logic controllers (using an InfoWorks Real Time Control scenario).

An optional fully-dynamic 2D surface flood simulation engine that is completely integrated with the pipe and surface-channel hydraulic simulation provides users with even more opportunities to accurately analyze interactions between the storm drainage network and above ground flooding and flood routes, even in highly urbanized areas. The results generated by these simulations allow for the development of state-of-the-art flood maps which are an excellent tool for visually representing surface water flood depths and demonstrating how flooding will affect the modelled environment.

InfoWorks SD has an exceptional ability to handle both pressurized and free-surface flows equally well with the same high-calibre, consistent quality of analysis applied to both open channels and closed conduits. Uniquely, InfoWorks SD can also model lateral inflows to swales and exfiltration from channels and ponds, and has a specific flow-routing equation for natural channels.

“InfoWorks SD is easy to use, while providing the level of accurate simulation and reliable analysis that stormwater professionals require”, Paul Banfield continues. “It can offer either event-based or real-time continuous simulations, making it ideal for infrastructure design, evaluation projects and real-time operational use.”

As part of the InfoWorks family of modeling solutions, InfoWorks SD users enjoy all the core benefits of using an InfoWorks solution. These include the fastest, most accurate and robust dynamic simulation engine in the industry. Developed over 30 years, the InfoWorks hydraulic engine is ideal for simulating large networks, real-time events or long-term scenarios.

InfoWorks SD also includes excellent multi-user model building and management capabilities and advanced, user-friendly, analysis tools within an accessible and recognizable interface. Its open and flexible approach to data formats also allows ease of data exchange with other applications. In common with other InfoWorks solutions, InfoWorks SD recognizes all GIS platforms, CAD data and asset management systems, and integrates seamlessly with other members of the InfoWorks family.

InfoWorks SD users benefit from the world-renowned expertise of Wallingford Software’s development and technical support staff, ensuring both continuous and innovative product development and ongoing professional support.

InfoWorks SD will be available with the release of InfoWorks v8.5 and will be demonstrated at Wallingford Software’s forthcoming International User Conference in the UK, September 11th-13th, the Canadian User Conference, September 19th-20th and then at successive trade shows including WEFTEC in San Diego, October 13th-15th.

Yorkshire h20 is one of the principal water and waste water treatment companies in the UK and had a problem with a lime dosing application at the Ruswarp h20 Treatment Works near Whitby,
Northern England.

Lime dosing is a classical Verderflex® application with many installations in the water industry and the following is a very successful installation by Verder UK’s sales team, which addressed the problems of an abrasive variable viscosity product causing excessive pump downtime and continuously high maintenance costs.

Originally, classical solenoid driven diaphragm pumps were being
used to dose Kalic® Liquid Lime, a viscous, alkali solution added to the water supply to maintain a neutral pH value. The problem occurred when these pumps had to operate at low flow rates.
Staff were constantly called out after the pumps became clogged with the viscous product and failed. As a solution, Verder recommended the replacement of these units with Verderflex® peristaltic pumps.

Pumps in this range can self-prime to a depth of 9.5m and are engineered to prevent clogging. They can handle highly viscous liquids and offer precise flow control, making them ideal for dosing applications such as this. They are also easy to maintain, as the hose is the only part of the pump that comes into contact with the product.

Five Verderflex® pumps have subsequently been installed at
the site by Verder UK, under the instruction of the consulting
engineers Earth Tech/Morrison. These include two VF15’s for pre
Kalic and two VF10’s for post Kalic dosing. A VF25 re-circulates
the solution to storage tanks. The new pumps are controlled by the
site’s PLC and utilise the existing inverters to give variable speed and flow as required. This system has replaced the twin controls for speed and stroke adjustment that were fitted with the diaphragm pumps.

The installation was carried out without interrupting the water
supply and no call outs have been experienced, dramatically reducing
both downtime and maintenance costs.
