JUNE 2013 WATER 15 Industry News Bil nger Water Technologies: A New Connection Passavant-Geiger GmbH, a wholly owned subsidiary of Bil nger SE, has acquired Johnson Screens, a global leader in screening products for water infrastructure, wastewater treatment, hydrocarbon processing and general ltration. Passavant-Geiger GmbH and Johnson Screens Inc will form the Bil nger Water Technologies Group, under which the companies can unite, complement one another and present their individual features to the market. Johnson Screens manufactures mechanical components for the separation of solids from liquids and gases and also offers related services from 11 locations around the world. The products are used for the extraction and treatment of drinking water. They also play an important role in wastewater treatment and re ning applications for oil and gas as well as other industrial applications. As a result of the take-over, Passavant-Geiger will double its output volume in the water and wastewater sector. In his statement, Joachim Foerderer, Passavant-Geiger CEO and CEO of the future Bil nger Water Technologies explained: "The strategic importance of this merger of two leading international companies is apparent not only from a glance at the key gures. With the integration of Johnson Screens we continue our global growth strategy and strengthen our position in the international competition over the long term." With locations in Europe, North and South America, Africa, Asia Paci c and Australia, the new group has a strong global footprint, creating new sales opportunities for its established brands such as Passavant, Johnson Screens, Geiger, Airvac, Diemme, Roediger, Noggerath and Screenex. Further important advantages are presented by the new access to important growth markets in the US, Brazil, India, South Africa and Australia. This new chapter in the corporate history of Passavant-Geiger and Johnson Screens Inc also enables new opportunities for comprehensive system solutions in many sectors such as the combination of innovative water well and treatment technologies. Pasteurisation Trial To Produce Recycled Water New research to demonstrate the effectiveness of pasteurisation for disinfecting recycled water has been initiated by the Australian Water Recycling Centre of Excellence. Pasteurisation, a long-established process used worldwide to disinfect and treat milk, involves the rapid heating and cooling of food, usually liquid, for a short period of time. The project, to be conducted at Melbourne's Western Treatment Plant, will use the same process to treat wastewater to a very high standard. It is expected that the water produced will be suitable for crop irrigation, livestock drinking and industrial use. The project will be led by a team from Victoria University with support by the Australian Water Quality Centre, Melbourne Water, WJP Solutions and two US-based companies, Pasteurisation Technology Group and Carollo Engineers. The project will test the effectiveness of pasteurisation for the Australian water industry and its potential to reduce energy and operational costs compared to conventional water disinfection processes. It will involve an ef cient heat exchange system that can capture and re-use waste heat. Australian Water Recycling Centre of Excellence CEO Mark O'Donohue says: "If successful, the project will demonstrate that pasteurisation can reduce treatment costs and energy requirements, and simplify the recycled water disinfection process, under rigorous conditions required by Australian Departments of Health." Pasteurisation is a standard process within the food industry, and the technology is robust and mature. Its application to wastewater treatment has recently been made viable by the use of modern heat recovery technology. Dr Peter Sanciolo, who is leading the research, said: "By utilising waste heat from burning biogas (a waste by-product of water treatment) or from engines generating electricity on-site to run the water treatment plant, pasteurisation disinfection technology may prove cost effective compared to purchasing electricity from the grid and using conventional disinfection treatments such as membrane ltration, ultraviolet light and chlorine." Pasteurisation for recycled water has been successfully trialled in California at the Santa Rosa's Laguna and the Ventura Wastewater Treatment Plants. Both US project partners, Pasteurization Technology Group and Carollo, worked on the pilot plant and this will bring technical expertise to the Australian trial. The Australian Water Recycling Centre of Excellence aims to enhance the management and use of water recycling by investing in research into practical solutions for securing Australia's future water supply. The Centre is funded by the Australian Government through the Water for the Future initiative. Innovation Supports Recycled Water Plant At Pakenham The of cial opening of the new Pakenham Water Recycling Plant provides residents with cheaper recycled water in their homes for toilet- ushing and garden watering. Now a further 2,000 homes in new estates of south-east Melbourne will have the option of two sources of water, thanks to AECOM's innovative engineering solutions at the plant. AECOM provided the technical solution to convert the water recycling plant into a state-of-the-art facility enhancing the quality of recycled water from Class C to Class A for residential use. Technical engineers from AECOM's UK, Canada and New Zealand teams worked on the South East Recycled Water Alliance comprising South East Water, Trans eld Services and AECOM. The Alliance has undertaken a $110 million, four-year program to upgrade Somers Sewerage Treatment Plant, construct three Class A water recycling plants (Pakenham, Mt Martha and Somers) and construct a bio-solids treatment and solar dryer facility at Mt Martha. Rex Dusting, General Manager Infrastructure for South East Water, said: "South East Recycled Water Alliance has brought AECOM's Chris Boyd.
