Nanofiltration Element for Municipal Water Application: Tapurim Series: TAPU-LS
Organics, microbes, viruses and most of metal ions with two or higher valence can be filtered by
Tapurim Series NF element, while part of sodium, potassium, calcium, magnesium ions, etc. can be
retained in the permeated water.
TAPU-LS Element is designed primarily for removal of organics while keeping most of the monovalent
ions retained in the permeated water, and is applicable to removal of organics and inorganics from raw
water with low salinity.
◎ The production of drinking water, such as: municipal waterworks, rural area drinking water
projects, etc.
