• Further three orders underline growing market acceptance

TOULOUSE, France, Aug. 8, 2008 -- Koch Membrane Systems Inc. (KMS), has announced the details of the three new orders for PURON™ modules through Veolia Water Solution & Technologies (VWS) in the south of France. These latest applications near Perpignan, Toulouse and La Rochelle, are all for municipal wastewater treatment applications, a sector in which KMS enjoying considerable success as a VWS-preferred supplier.

The project at Sigean on the Mediterranean coast near Perpignan will protect the quality of local bathing waters in this popular holiday destination. The population of 5000 can double during the Summer season and the finished project will have a capacity of 2130m³/day when it is completed in 2009.

PURON was also chosen for the MBR project at Nailloux for its state of the art characteristics and its ability to keep pace with the rising population of the area which averages 10 percent per annum thanks to its proximity to Toulouse. Like many areas of southern Europe, Haute Garonne receives little rainfall and MBR permits reuse of vital resources. Completion is scheduled for Q3 2008 and the plant will process 965 m³/day.

The third VWS project at St. Jean de Liversay near La Rochelle will process 289 m³/day of wastewater.

A key advantage of the patented PURON system is the use of a single header with hollow fibers that are fixed only at the bottom. The sealed upper end of the fibers is allowed to float freely. This eliminates the build-up of hair and fibrous materials that can clog the upper end of membrane fibers in MBR designs that employ both a top and bottom header. Solids and particulates, including bacteria, are retained by the membrane and remain on the outside, while permeate is drawn through the membrane to the inside of the fibers. Outside-to-inside technology such as this provides optimal solids management and a high flow-rate, while using up to 50 percent less energy than other MBR systems. With the recent introduction of 1500 modules, PURON can now be ordered in configurations with 1500, 500, and 250 square meters of membrane area.

MBR systems with submerged membrane modules are increasingly used for some of the toughest wastewater treatment applications including sewage treatment for municipalities and treatment of wastewater for beverage, textile, food, paper, and chemicals industries. By using MBR systems to recycle process water, industrial companies cut wastewater disposal costs and reduce consumption of fresh water.

Koch Membrane Systems Inc. is a designer and manufacturer of state-of-the-art membrane cartridges and elements, as well as complete membrane systems.
