Water societies discuss priorities and issues ahead The officers of major water and wastewater organizations in North America met recently in Washington, DC, USA, to discuss their initiatives, priorities and programmes for 2007. ‘This is a wonderful chance for us to build relationships, discuss areas of collaboration and understand each others’ perspectives on major issues,’ said Jack Hoffbuhr, Executive Director of the American Water Works Association (AWWA). ‘Our hope is that this understanding will enable us to serve our members more effectively as we work to protect the public health by providing a safe and secure water supply.’ Participating organizations included the AWWA, the Association of Metropolitan Water Agencies, the National Association of Clean Water Agencies, the National Association of Water Companies, the National Rural Water Association, the National Water Resources Association, and the Water Environment Federation. The discussion focused on initiatives and projects that provide partnership opportunities, such as communicating the value of public water and wastewater services, and the need for reinvestment in infrastructure. The officers discussed issues the industry is expected to face in the current Congress, such as the ‘2007 Farm Bill’, where the AWWA will seek support for efforts to direct significantly more financial and technical resources into protecting public water supplies. In addition, the meeting provided an opportunity to discuss other problems, such as the potential contamination caused by endocrine disrupters and pharmaceutical products, which are flushed down toilets and end up in public water supplies in extremely low concentrations.

H2O Innovation signs two US contracts
GEA Filtration of Hudson, Wisconsin, USA is offering a membrane-based filtration pilot-plant which, it says, provides accurate test results, with reliable scale-up to full production, for the recovery of a wide range of active pharmaceutical and biotechnology products in accordance with current Good Manufacturing Practice (cGMP). According to the firm, the Type ‘R’ Pharma is suitable for use in clean-rooms to carry out pilot studies on a range of filtration technologies, including microfiltration, ultrafiltration, nanofiltration and reverse osmosis. It is able to house a variety of membrane configurations (with a membrane area of up to 14 m 2), including spiral-wound, ceramic and hollow-fibre formats. It is designed for batch or continuous operation, and is designated a clean-inplace system. The Type R produces accurate results that are replicated during full production, claims the company. To achieve this, GEA says that it has taken great care in the plant’s design. All components and instruments have been carefully chosen to provide maximum safety and accuracy. The plant uses frequencycontrolled pumps to minimize product damage, limit heating and maintain correct operating parameters over a wide range of flow rates and pressures. Various control options are available, which depend on the location and site philosophy. For example, conventional controllers can be used for various process parameters, including feed pressure, recirculation flow and operating temperatures (with the option of data-logging key process parameters in accordance with
Canada’s H 2 O Innovation (2000) Inc has signed two contracts through its US subsidiary Membrane Systems Inc (MSI). The contracts, which have a combined value of over US$1.4 million, cover the supply of drinking water treatment plants for the cities of Palm Coast and Boynton Beach, both located in Florida. The Palm Coast system will produce drinking water at a flow rate of 8500 m3 (2.25 million gallons) per day to supply the city of 45 000 people. The system consists of two trains of low-pressure, reverse osmosis units. These use 336 membrane elements that are designed to treat well water that has high hardness and organics. The units will be designed and prefabricated to the maximum extent for on-site assembly. The existing system at Boynton Beach will be upgraded to improve its capacity to meet the increasing demand for drinking water. Using 648 membrane elements in the existing and expanded trains, the facility will have a total capacity of 33 000 m3 (8.7 million gallons) per day. MSI will provide the membrane elements, pressure vessels and ancillary equipment necessary for the on-site implementation and upgrade of the water treatment plant. Commenting on the project at Boynton Beach, M. Ashwin Desai, General Manager of MSI, said: ‘Our expertise, reputation and satisfactory project execution and start-up of the existing system, which was also supplied by Membrane Systems, were key factors in winning this tender.’
