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 microfiltration (MF), ultrafiltration (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
Demole® Series of nanofiltration membrane is specially developed for the material concentration and separation fields. They are suitable for industries such as salts mine recycling, zero discharge of high saltwater, material separation, and concentration.
DNF 1 has a high removal rate of total organic carbon (TOC) and a medium rejection rate of inorganics salts. It is embedded with ultra-low pressure and pollution-resistance membrane preparation technology to realize the double improvement of service life cut down the energy consumption.
DNF2 has a high rejection rate for multivalent ions, a low rejection rate for monovalent ions, accurate molecular weight interception, and is also suitable for the separation and purification of small molecule pharmaceutical drugs.
Features
Specifications
PS. 1. The performance parameters area measured after 30 minutes of stable operation of the system
2. The deviation range of water yield is ± 15%
