Ultrafiltration Membrane Components

■ Internal Pressure Membrane Module

Ultrafiltration membrane technology

It can remove pollutants such as bacteria, viruses, colloids, macromolecular organic matter, algae, etc.

PES membrane, high efficiency and high yield

The membrane pore size is 0.01μm, with high interception rate. The effective membrane area of ​​a single membrane module is large and the water production is high.

Easy maintenance, long service life

The membrane components have strong oxidation resistance, strong pressure resistance, are easy to clean and maintain, and have a long service life.

Wide range of applications

It is suitable for water purification of well water, mountain spring water, rainwater and pretreatment of seawater desalination.

■ External Pressure Membrane Module

Ultrafiltration membrane technology

It can remove pollutants such as bacteria, viruses, colloids, macromolecular organic matter, algae, etc.

Using PVDF hydrophilic membrane

It has strong chemical stability and is resistant to pollution. The membrane components are easy to clean and maintain and have a long service life.

External pressure structure design

Compared with the internal pressure structure, it can withstand higher influent turbidity and reduce the pretreatment process.

Wide range of applications

It is suitable for water purification of river water, reservoir water, mountain spring water, pretreatment of seawater desalination, industrial wastewater treatment, sewage reuse, etc.
