The principle of porous tubular ceramic membrane

The principle of the filtration is based on two opposing effects: on the one hand, the particles are transported by the filtration flux to the membrane where they cause an increase in concentration; on the other hand, concentration differences are again reduced by the turbulence of the cross-flow and by Brownian motion of the particles.

Ceramic membrane separation has greatly improved work efficiency and quality.

During filtration by means of ceramic membranes made by JIUWU ceramic membrane manufacturer, the medium to be filtered flows through the channels of the membrane support.

All particles whose size exceeds the pore radius of the membrane are retained.

The particles /molecules build up in the concentrate.

The filtrate permeates through the pores and depending on the procedure is subjected to subsequent process stages.

This filtering method is also called "cross-flow filtration" or "dynamic filtration".

Cross-flow management can achieve stable fluxes.

Still, the cleaning of cross-flow installations needs to be applied from time to time.

Cleaning is performed by means of backward flushing or chemical cleaning.

There are various ceramic membranes for water treatment in the market, while JIUWU ceramic membranes for wastewater treatment perform very well.

• Business Description: JIANGSU JIUWU HI-TECH CO., LTD has become the biggest ceramic membrane producer and system integration provider in the world since 1997.
  
  JIUWU HI-TECH has advance R&D center, many material scientists, experienced engineers and workers and more than one hundred of pilot.
  
  JIUWU HI-TECH provides total solution from trial, design , manufacturing, installation, commissioning, after-sale service to membrane replacement.
  
  JIUWU HI-TECH cooperates with OEM.
  
  JIUWU ceramic membrane element has an asymmetrical structure consisting of three layers, which are filtering layer, an intermediate layer, and the support layer.
  
  The pressure drop of such asymmetrical structure is lower than that of the symmetrical structure of another membrane, which means that the ceramic membrane element has a better recovery.
  
  JIUWU ceramic membrane element adopts dynamic cross-flow filtration mode which is completely different from dead-end filtration and filter-cake filtration.
  
  The feed flows into the membrane channel at a cross flow velocity.
  
  Under a certain pressure (Trans-Membrane Pressure), small molecular substances or clean liquids pass through the membrane layer vertically to permeation, macro molecular substances or solids are trapped by the membrane, thereby achieving the purpose of clarification, concentration and purification.
  
  Cross-flow filtration mode can achieve stable fluxes.
  
  JIUWU ceramic membrane element is an ideal choice for high value-added products and demanding selective separations from solid-liquid fluid streams.
  
  The compact multi-channel geometry and high permeability are optimized for bulk processing applications.
  
  JIUWU ceramic membrane element has a wide range of application-specific of geometries with pore size from 2nm to 1200nm, making it ideal for micro filtration ultra filtration, nanofiltration.
  
  JIUWU ceramic membrane element is available in sizes ranging from small laboratory devices through individual modules of 0.1 square meters surface area, ensuring the ability to evaluate and scale up processes to any size.
