Company Profile
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.
Product Description
ResaltTM Series of reverse osmosis membrane products are specially developed for desalination of medium and high salinity raw water, with the characteristics of high desalination rate and stable operation. It can be widely used in coal chemical industry, boiler feed water, reclaimed water reuse and material concentration.Special grid design is adopted in the inlet channel, which makes the product have more obvious advantages in pollution resistance and easy cleaning.RBW product has high desalination rate of sodium chloride, high chemical cross-linking degree, chemical cleaning resistance, suitable for treatment of brackish water.
Our Advantages
- High desalination rate;
- Excellent flow channel design to reducing fouling and blocking problem;
- Advanced patented permanent hydrophilic technology, make membrane super anti-fouling.
- Excellent chemical cleaning resistance
