Membrane

NF series nanofiltration membrane components are developed by Qicheng Company to remove organic substances, microorganisms, viruses and most of the divalent and above and metal ions in water, while retaining sodium, potassium, calcium, magnesium plasma and so on.

Nanofiltration   membranes   still   have   a   high   water   flow   rate   under   low   operating   pressure,   which   can   remove most   of  the   macromolecular  organics,   heavy   metal   ions,   divalent   salts,   and   COD   in  the  water,  while   retaining some  of  the  smaller  organic  and  monovalent  Salt.

The HS series reverse osmosis membrane components, developed by Qicheng Company for the desalination of high salt water, are polyamide composite membranes.

FR series reverse osmosis membrane components are polyamide composite membranes developed by Qicheng Company for desalination of high salt brackish water. They have the characteristics of low pressure operation, high water yield and good desalination performance.

The XLP series extreme low pressure desalination reverse osmosis membrane components, developed by Qicheng Company for surface water and groundwater, are polyamide composite membranes.

ULP series low pressure desalination reverse osmosis membrane components are polyamide composite membranes developed by Qicheng Company for surface water groundwater.

LP series reverse osmosis membrane components are polyamide composite membranes developed by Qicheng Company for desalination of brackish water. They have the characteristics of low pressure operation, high water yield and good desalination performance.
