Quick Details

  • Model Number: TRANSFILMTM TFN90-400 / TFN90-82
  • Brand Name: TRANSFILMTM



TRANSFILMTM TFN90-400 / TFN90-82 elements can separate organics and salts from water and increase permeability while offering superior salt rejection.They significantly reduce operating costs and provide optimal hardness rejection for softening applications and the removal of pesticides, bacteria or viruses. TRANSFILMTM TFN90-400 / TFN90-82elements are designed to provide high rejection of natural organic materials and moderate rejection of total hardness, while offering energy and cost savings.

Suitable for:

l  removing total organic carbon (TOC) and trihalomethane (THM) precursors.

l  high salt rejection with ultra-low-pressure operations, increased energy savings, and significantly lower installation and operating costs.

l  various operating conditions with 4″and 8″elements.
