Uf Membrane Technology - China

Ultrafiltration (UF) is a variety of ceramic membrane filtration in which forces, such as pressure or concentration gradients, cause separation through the semi-permeable membrane.

High molecular weight suspended solids and solutes remain in the so-called retentate while water and low molecular weight solutes pass through the membrane in the permeate (filtrate).

The pore size of the ultrafiltration membrane is in the range of 0.01μm ~ 0.05μm, suitable for the separation, concentration and purification of macromolecules and small molecules.

Application of Ceramic ultrafiltration Membrane UF technology can be used to remove particulates and macromolecules from raw water to produce potable water.

It has been used to replace the existing secondary (coagulation, flocculation, sedimentation) and tertiary filtration (sand filtration and chlorination) systems used in water treatment plants or as stand-alone systems in isolated areas with a growing population.

When treating water containing highly suspended solids, primary (screening, flotation and filtration) and some secondary treatments are often used as a pretreatment stage to incorporate ultrafiltration into the process.

When water recovery is simple, very little processing is often required.

However, when more in-depth processing is required, industry standard procedures include the use of UF, which means removing the physical solids from the water by passing them through a semipermeable membrane.

With ultrafiltration, the solids are primarily captured by the filter and discarded.

Circulating water can also be used in a variety of industrial applications including water supply to boilers or cooling towers, pH control, cleaning equipment, hard beds and vehicles, fire fighting, rinsing or process water for manufacturing industrial lines, toilet flushing, dust control, construction activities Mix with concrete.

Ultrafiltration ceramic membrane is often used to pre-treat surface water, seawater and bioprocessed municipal water upstream of reverse osmosis plants.

Industries that consume large amounts of water or discharge highly toxic wastewater may use ultrafiltration to recover water.

These include chemicals, steel, plastics and resins, paper and pulp, pharmaceutical and food and beverage industries, including soft drinks and canned foods, and electricity, water and wastewater treatment plants.

Ultrafiltration is used to recycle flow or add value to later products and more.

In many cases ultrafiltration (UF) is used for prefiltration in reverse-osmosis plants to protect the reverse-osmosis process.

Ultrafiltration is an effective means of reducing the silt density index of water and removing particulates that can foul reverse osmosis membranes.

• 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.
