Membrana announces a new agent in Malaysia for Liqui-Cel membrane contactors -- CHARLOTTE, NC, Feb. 2, 2007 -- Membrana is pleased to enter into an agency agreement with Nextech SDN BHD as the local sales agent responsible for selling and servicing Liqui-Cel Membrane Contactors in Malaysia. Nextech has offices in Kuala Lumpur as well Penang which will offer Malaysian customers excellent access to Liqui-Cel® Products.

Allen Pittman, Membrana's vice president, sales and marketing for industrial separations, says, "We are excited to add Nextech's expertise and experience to our team. They will be a valuable addition to our current sales channels."

This agreement commenced on Jan. 2.

The company's membrane contactors are used around the world for adding or removing oxygen (O2), carbon dioxide (CO2) and nitrogen (N2) to or from different liquids in the semiconductor, power, pharmaceutical, photographic, food & beverage, and many other industries.

For example, it's known that O2 negatively impacts many processes; it is corrosive and can oxidize materials. In the power and industrial areas, piping and equipment are susceptible to corrosion. Specifically to the semiconductor market, high levels of O2 can cause lower wafer yields.

Additionally, CO2 negatively impacts performance of electrodeionization (EDI) and ion exchange. The contactors offer a modular solution for O2/CO2 removal before these processes without chemicals. They're also used to add gasses to liquids to enhance megasonic cleaning.

The beverage industry looks to membrane contactors for carbonation, nitrogenation and O2 removal. These reflect only a few examples of the variety of applications where the membrane contactors are used.

Membrana's Industrial Membrane Group also manufactures a variety of membranes used for filtration in various industries and applications.

Membrana GmbH is a wholly owned subsidiary of Polypore Inc., a growing high technology filtration company specializing in microporous membranes. Polypore's flat sheet and hollow fiber membranes are used in specialized applications that require the removal or separation of various materials from liquids, primarily in the ultrafiltration and microfiltration markets. Based in Charlotte, NC, Polypore is a global leader with manufacturing facilities or sales offices in 10 countries serving five continents."

Sewage treatment plant reports success with Hach Lange LDO -- LOVELAND, CO, Feb. 2, 2007 -- Between 60 and 70% of the energy consumed by sewage treatment plants is used to aerate the activated sludge. Strategies aimed at reducing energy consumption are therefore usually focused on optimising the oxygen transfer into the aeration tank. All control systems are based on exact and precise measurement of the oxygen concentration. For process engineers, therefore, the issue is not whether but how the oxygen concentration can be measured precisely and with a high degree of accuracy. This question was addressed two years ago at the main sewage treatment plant in Vienna. It was decided that the best solution was the optical LDO sensor from HACH LANGE GmbH...

Cooper Union book signing, seminar focuses on world's water in 21st century NEW YORK CITY, Feb. 1, 2007 -- Water-Works: The Architecture and Engineering of the New York City Water Supply (Monacelli Press, 2006) offers a fascinating story about a monumental restoration project led by Cooper Union's architecture professor Kevin Bone. He and his students (over nine years) discovered, catalogued and restored archives of historic drawings, photographs, paintings and maps of New York's complex water supply system. As a result of Professor Bone's work, the N.Y. Department of Environmental Protection created a permanent archive to house these priceless documents. Cooper Union is bringing together a noted panel of world experts Feb. 8, at 6:30 p.m., to discuss the evolution of New York City's water system (from 18th-century ponds to Water Tunnel #3) and the challenges of providing clean drinking water in rapidly developing countries. They include former chief of the New York City DEP Albert F. Appleton; Peter Gleick, president and co-founder, Pacific Institute for Studies in Development, Environment and Security and MacArthur Fellow; and Gerard Koeppel, scholar, journalist and author of Water for Gotham: A History, to name a few. With one billion people living without safe drinking water, where will the clean water come from? What will we do next? Access to clean water is one of the biggest environmental issues facing humanity this century...
