KMS Installs PURONĀ® HF Modules at a Major Steel Mill in Inner Mongolia
Published Date: July 14, 2014
Koch Membrane Systems, Inc. (KMS), world-class developer and manufacturer of innovative membranes and membrane filtration systems, announced today that it has installed its PURON® HF ultrafiltration (UF) modules at a major steel mill in Inner Mongolia, China. The system is the first large application of the PURON HF product in the metals industry, with a capacity of 57,600 cubic meters per day (15.2M gallons per day).

PURON HF ultrafiltration modules are ideal for high solids applications and are an ideal choice for applications such as reverse osmosis (RO) pretreatment, surface water treatment and tertiary wastewater treatment. PURON HF systems can provide water recoveries of greater than 95% and produce consistent, high-quality water that meets or exceeds most regulatory requirements.

At the steel mill, the treated water will serve as mill service water and will meet permeate turbidity requirements of less than 0.2 NTU, and a silt density index (SDI) of less than 3.

PURON HF was selected after a pilot demonstration showed better permeate quality, lower energy consumption, and lower chemical consumption compared with other competitive products. The submerged reinforced PURON HF modules feature supported membrane fibers, which virtually eliminate breakage risks. This results in a high throughput, compact wastewater solution that can be implemented for a low lifecycle cost.
