Pretreatment Membranes Selected for Seawater Desalination Project
Koch Membrane Systems (KMS) has been selected to provide ultrafiltration pretreatment membranes for one of Asia's largest seawater desalination plants. The system will supply 28,000 m3/day for the reverse osmosis system that will produce boiler make-up at the Liaoning Zhuanghe Power Plant in Liaoning Province, China.
WILMINGTON, MA, Aug. 9, 2006 -- Koch Membrane Systems (KMS) has been selected to provide ultrafiltration pretreatment membranes for one of Asia's largest seawater desalination plants. The system will supply 28,000 m3/day for the reverse osmosis system that will produce boiler make-up at the Liaoning Zhuanghe Power Plant in Liaoning Province, China.
Supplied by Beijing Lucency Enviro-Tech Co., Ltd., the system will feature 200 TARGA®-10 cartridges from KMS. The first two trains, with 40 cartridges each, will be commissioned in August 2006, with the remaining three trains commissioned in late 2007.
"We are proud to be a part of this prominent example of exploiting alternative water sources in China," said John Morrison, senior vice president of sales and marketing at KMS. "This large-scale seawater desalination project will serve as a model for addressing China's serious water shortage. Our TARGA UF membranes provide a reliable and cost-effective pretreatment solution for highly-variable and difficult-to-treat seawater RO desalination plants."
TARGA-10 hollow fiber membrane cartridges have a 10-inch diameter and deliver 60 percent more product water than conventional 8-inch cartridges, resulting in significant cost savings. By using TARGA-10 cartridges, system size is significantly reduced because of the additional flow per cartridge. These smaller systems require 50 percent less floor space, resulting in substantial savings in building costs. Additionally, the larger capacity cartridges reduce the number of connections, thereby improving reliability and further lowering costs.
"Once installed, more than 90 mgd of water from a variety of sources in China will be treated using our TARGA products," Morrison said. "This UF hollow fiber cartridge has become the standard in China since it was introduced almost three years ago."
Unlike cartridges that use membranes that have larger pores, TARGA-10 cartridges feature true ultrafiltration membranes and are designed to remove particulates, colloids and other large molecular weight components while reducing turbidity to less than 0.1 NTU.
The membranes are made from a KMS patented polymer that has been successfully used in municipal and industrial water treatment plants around the world for more than a decade.
