Aqua Clear Water Treatment Specialists Nanofiltration




Aqua Clear Water Treatment Specialists manufactures a full line of commercial and industrial nanofiltration (NF) systems that utilize membrane filtration. Nanofiltration is a membrane separation process which removes many dissolved high molecular weight compounds from the water feed. Nanofiltration membranes are also known as “softening membranes” because they will remove the hardness from feed water but leave the majority of the lower molecular weight ions in the water.  Nanofiltration membranes can also remove large organic molecules with molecular weight above about 1,000 Daltons such as color from water. Nanofiltration systems have replaced reverse osmosis membrane treatment in many applications where removal of just the hardness and large organics  is needed for the end process. The most common applications for NF systems are surface water and fresh groundwater, also being used recently in the food processing industry.

Aqua Clear Water Treatment Specialists manufacture and specialize in NF systems from 500 to 1,000,000 gallons per day.
