Product Description

About Shuiyi: 
After years of honed in the competition, SHUIYI has become one of the few manufacturers in the industry with a full range of membrane technologies and products including micro filtration (MF), ultra filtration (UF), nanofiltration (NF) and reverse osmosis (RO).
Our membrane products are widely used in the application fields of municipal sewage reclamation, industrial wastewater zero discharge, reclaimed water reuse, pure water preparation, highly polluting wastewater treatment, river restoration, decentralized rural  sewage treatment, process concentration and separation, etc., with rich application experience and engineering project cases.
Introduction
Tapfilm^TM Series of membrane elements are nanofiltration membrane products specially developed for water purification field, which are suitable for advanced treatment of drinking water, surface water and groundwater. It has a high removal rate of biological pollutants, antibiotics, pesticide residues and heavy metal, a medium removal rate of mineral salt with a low operation energy consumption.
Special grid design is adopted in the inlet channel, which makes the product have more obvious advantages in pollution resistance and easy cleaning.
TPW1 is mainly for the removal of organic matter in water, retaining most of the monovalent ions, and is suitable for treatment of low salty water.
TPW2 has high removal ability for divalent ions, can remove organic matter and most hardness in water, and ensure the taste of purified water.
TPW3 is mainly used to remove most of organics and inorganics in medium and high salty water.

Features

1. High removal of organic matter;
2. Low pressure operation, low energy consumption;
3. Unique physical design and advanced anti-fouling technology reduce the demand of chemicals;
4. High and stable pure water production with the innovative high flux technology
