Product Introduction

The OWUF external pressure ultrafiltration membrane module breaks through PVDF ultrafiltration membrane super-hydrophilic modification technology and a new detachable structure design of the membrane module, solving the problem of membrane fouling in ultrafiltration membrane applications. It has higher pollutant retention capacity and larger filtration area, ensuring long-term stable operation of the system. It is one of the major achievements of the National "Twelfth Five-Year Plan" Water Special Project and has won honors such as "Zhongguancun New Technology and New Product" and "Beijing New Technology and New Product".

Product Features

  • Good Permeate Quality Narrow membrane filament pore size distribution, high filtration precision, permeate turbidity less than 0.1NTU;
  • Strong Anti-Fouling Ability Component pulsating operation, proprietary homogenizing disc structure design, more uniform water and air distribution, effectively controlling pollution;
  • Low Maintenance Cost Detachable structure design, reusable parts, saving costs;
  • Long Service Life Adopts 3H membrane making technology, with high-precision gradient pore structure, service life more than 5 years.
