Internal Pressure Ultrafiltration Membrane Module

Product Description

Ditta Water’s internal pressure ultrafiltration membrane module is made of polysulfone (PS) material and has undergone hydrophilic modification treatment, which can withstand high concentrations of oxidants and fully inhibit the reproduction of microorganisms. Among the internal pressure ultrafiltration membrane modules used in industrial applications, the membrane filaments of the Ditta Water series ultrafiltration membrane modules have a small nominal diameter and can remove almost all particles, bacteria, most germs and colloids; their extremely high porosity makes The Ditta Water series of ultrafiltration membrane modules can obtain relatively similar fluxes to microfiltration, and are therefore a better choice than microfiltration in most cases. Internal pressure ultrafiltration has excellent flushing effect in forward flushing and backwashing.

DWUFP ultrafiltration membrane module has the following main technical characteristics and advantages:

(1) Hydrophilic modification treatment, the inner diameter of the membrane is larger, the pollution resistance and recovery after pollution is strong, the membrane flux is larger.

 (2) The decentralized and centralized water distribution method improves the pollution resistance, which is conducive to backwashing and chemically strengthened backwashing.

(3) Thicker membrane wall, special root protection, long service life

(4) Small molecular weight cut-off , high filtration accuracy
