Koch Membrane Introduces Nanofiltration Membrane
Selective Rejection Membrane Expands Fluid Systems Product Range
Koch Membrane Systems, Inc. (KMS) extended its range of selective rejection nanofiltration (NF) membranes for water and wastewater treatment, with the launch of its new Fluid Systems(tm) TFC®-SR2(tm) element.
"The Fluid Systems SR2 features groundbreaking characteristics of very low pressure, high specific flux membranes ideal for efficiently removing divalent ions such as hardness and sulphate, and dissolved organics from municipal drinking water or industrial wastewater streams," said Alan Franks, senior development engineer for KMS. "Hardness rejection is typically 97 percent and organic rejection over 90 percent for organics with molecular weight in the range of 300 daltons."
Operating at extremely low pressures, typically 50 psi (3 Bar), the membrane is very energy efficient and capable of producing more water per square meter (m2) of membrane surface area than competitive products, Franks said. It is ideal for municipal and industrial, for example, treating large volumes of drinking water in municipal plants to remove dissolved organics and hardness.
The Fluid Systems(tm)TFC®-SR2(tm)membranes are available in 4-inch and 8-inch diameters and in standard 40-inch or Magnum® 60-inch lengths. The SR2 has been incorporated into ROPRO® system design software by KMS.
Franks said the latest innovation, one of several new and improved RO/NF membrane products, maintains KMS' reputation as the world leader in membrane separation technology.
