TAPU Series: Nanofiltration Element for Municipal Water Application

TAPU Series: Nanofiltration Element for Municipal Water Application


Organics, microbes, viruses and most of metal ions with two or higher valence can be filtered by Tapurim Series NF element, while sodium, potassium, calcium magnesium ions, etc. can be retained in the permeated water.

TAPU-LS Element is designed primarily for removal of organics and inorganics from raw water with low salonity.

TAPU-MS Model has higher rejection rate of monovalent ions while maintaining a proper rejection rate of organics, which is applicable to the removal of organics and inorganic matters in mid-salinity raw water.

TAPU-HS has a rejection rate at 80-85% for chlorides, applicable to the rejection of organic and inorganic matters in mid and high-salinity raw water.



This membrane element is developed by utilizing the technology of controllable formation in separation layers, and is designed for waters with middle and high salinity to meet the requirements of healthy drinking water.

The use of brand-new LD (low pressure difference)-mil feed channel spacer improves the fouling resistance while reducing the energy consumption.

The entire series of elements have been officially authorized by " Hygiene Permit for Products Related to Drinking Water Hygiene Safety", thus ensuring the safety of membrane element application.
