KMS Provides PURON MBR Ultrafiltration Modules For Power Plant In Inner Mongolia

Single header design reduces energy, minimizes downtime, and increases flux

Koch Membrane Systems, Inc. (KMS), world-class developer and manufacturer of innovative membranes and membrane filtration systems, announced recently that it supplied PURON membrane bioreactor (MBR) ultrafiltration modules to a power plant located in Inner Mongolia, China. The project is the first in China’s power industry to use PURON MBR membranes for water reuse.

Municipal wastewater will be treated in an aerobic MBR using PURON hollow fiber membranes, followed by reverse osmosis (RO). The treated water will then be used as boiler make-up water. The plant has a capacity of 18,000 cubic meters per day (4.8M gallons per day).

PURON modules feature a unique single header design, with reinforced braided hollow fibers fixed only at the bottom, virtually eliminating clogging. They produce high-quality effluent, require a small footprint, and eliminate the need for secondary clarification. Unlike conventional wastewater treatment technology, PURON MBR ultrafiltration modules provide a physical barrier to bacteria.

Only PURON modules position the aeration nozzle in the center of the fiber bundle to scour the entire fiber length and minimize power consumption. The sealed upper ends of the fibers are allowed to float freely. The modules are submerged in activated sludge and a slight vacuum draws water from the outside wall of the fiber to the inside, where it flows as clean filtrate.

“We are extremely pleased that the PURON MBR modules were selected for this major power plant project,” said Pang Ruming, Asia-Pacific Commercial Director of the Water and Wastewater business for KMS. “We are confident that the modules will deliver a robust membrane, low energy consumption, and low chemical consumption compared with other membrane alternatives.”
