Tubular microfiltration membranes

MBR Membrane Products--Tubular Membrane

Products Introduction

Poseidon super alkali/acid-resistant tubular membrane is an internal pressure mosaic structure, the functional separation layer material can be designed according to the characteristics of the material system as PPESK, PVDF, PES, PPBES, etc., and the external material is modified PET high-strength support material.

Product Features

• Special sealing materials are used to fix a certain number of membrane tubes with specific diameters inside the membrane shell to form a tubular membrane module.  When applied, the material to be treated enters the inner lumen of the membrane tube with a specific separation aperture under a certain pressure. The produced water containing small molecules is separated and permeated through the membrane wall, and the concentrated liquid is discharged from the other end of the membrane tube, which has the following technical characteristics:

• With double layer structure, the inner layer has small pore size and uniform and consistent distribution, the outer layer is loose and high porosity;

• Inlaid structure, with strong wear resistance and long life;

• The special functional layer on the inner surface has hydrophilic and smooth characteristics, and has excellent anti-pollution performance.

Product Advantages

• High water flux: membrane porosity of more than 70%, the same transmembrane pressure, flux increased by more than 30%.

• High separation precision: Membrane pore of the separation layer is uniform and the pore diameter is adjustable from 0.01 to 0.2μm, which ensures the filtration precision of the membrane.

• Low operation cost: High-speed cross-flow of the original liquid in the membrane tube, pollutants are not easy to attach on the surface of the membrane, with obvious advantages of water-saving, cleaning agent-saving and energy-saving.

• Long service life: Membrane surface prepared by polar polarization process has strong hydrophilic group, which reduces the contamination phenomenon caused by hydrophobic pollutants, high membrane flux recovery rate, high pressure strength, and the service life can be as long as 5-10 years.
