industrial news EPA introduces water quality trading pilot schemes
Membrane technology short course The yearly Practical Membrane short course is taking place in College Station, Texas, USA, between 27 April and 1 May 2003. The objectives of the course are to review the fundamental principles of membrane technology (including membrane selection, system design, economics and practical applications), highlight new technology developments and discuss the major applications of microfiltration, ultrafiltration, nanofiltration, reverse osmosis and pervaporation in food processing, chemical processing, wastewater & water treatment, and general industrial processing.There will also be pilot plant demonstrations to familiarize attendees with the practical aspects of membrane technology. The, course's technical programme include: 'Basic Principles of Membrane Separations' Prof. M Cheryan; 'Pre- and Post-treatment of Process Liquids in Membrane Applications' Dr J Strasser; 'Parameter Optimization, System Design and Components for a Continuous Membrane System' Dr N Singh; and 'Membrane Cleaning and Sanitizing - Common Mistakes' D L Schmidt.The registration fee for the short course and pilot plant demonstrations is US$1395, which includes course manuals, daily lunch and refreshments and the graduation luncheon (Wednesday 30 April).
The Environmental Protection Agency (EPA) has announced a Water Quality Trading Policy that is aimed at cutting industrial, municipal and agricultural discharges into US waterways. The trading policy seeks to support and encourage states in developing and putting in place water quality trading programmes that meet the requirements of the Clean Water and federal regulations in a more flexible wag as well as reduce the cost of improving and maintaining the quality of the country's water. The water quality trading will use economic incentives to improve water quality. It allows one source to meet its regulatory obligations by using pollutant reductions created by another source that has lower pollution control costs. The standards remain the same, but efficiency is increased and costs are decreased. Under the policy, industrial and municipal facilities would first meet technology control requirements and then could use pollution reduction credits to make further progress towards water quality goals. The EPA is providing more than US$800 000 in funding for technical and other support for 11 trading projects across the US. f

Sludge drying plant order As part of an extension progamme, Andritz AG has been selected to supply a complete sludge treatment system to a wastewater treatment works near to Paris. The sludge treatment system will be used to dry dewatered sludge from the site's two existing wastewater treatment plants. It will comprise three drum drying lines, which will evaporate a total of 21 000 litres of water per hour, reducing the moisture content of the sludge to less than 10%. On a yearly basis the plant will be able to treat 267 000 tonnes of wet sludge. The dried product will be used as fertilizer and as fuel in the cement industry. Andritz currently has eight sludge drying plants under construction; one being a large facility in Singapore, with a capacity of 470 000 tonnes of wet sludge. As a leading company in sludge treatment Andritz can offer customers complete systems through its expertise in thickening, dewatering and drying technologies. Contact: Austria.
