8 Inch PVDF Material UF System 200mm Hollow Fiber Ultrafiltration Membrane

8 inch Ultafiltration(UF) Membrane Modules for Purified Water Treatment with Pore Size 0.03um PVDF material

Ultrafiltration (UF) is another reliable and cost effective water treatment method.

This separation process is used in industry and research for purifying and concentrating macromolecular solutions, especially protein solutions with other applications including

• Process and waste water treatment
• Filtration of effluent from paper pulp mill
• Cheese manufacture (using ultrafiltered milk)
• Removal of some bacteria from milk
• Fruit juice concentration and clarification
• Laboratory grade manufacturing

The ultrafiltration membrane pore size creates a barrier to suspended solid, bacteria, colloids and viruses whilst still allowing passage of ions. As such, the mineral content of water passing through an ultrafiltration membrane does not appreciably change (further removal of mineral contact might be achieved through the use of Ion exchange resin treatments such as water softening, deionisation or demineralisation depending on the fuller scope of the process required).

UF membranes operate at much lower pressures than Reverse Osmosis (RO) membranes and require a higher degree of cross-flow to prevent plug fouling.

A more recent development in membrane technology, the cost of ultrafiltration membranes has reduced considerably in recent years, making it a much more effective cost option for a number of applications, including river extraction. Ultrafiltration is also often used as a very effective pre-treatment to reverse osmosis.

Typically employed in hollow fibre construction, operation of ultrafiltration membranes can be from outside-to-in (i.e. fed from outside the fibre with permeate collected from within) or inside-to-out, dependent upon the specific manufacturer and application. The robust construction of the fibres generally enables periodic back flushing of membranes to reduce plug fouling. The cleaning of membranes is also enhanced by the introduction of chemicals, such as sodium hypochlorite or sodium hydroxide, via a dedicated Clean in Place (CIP).

We,Hangzhou Kaihong Membrane Technology Co.,Ltd, is established on the year of 2003. We specializes in manufacturing UF and MBR membrane modules. We own more than 20 years of experience for the applying of UF and MBR membrane modules. Our products have been used in more than 1000 water treatment plants. We also have more than 2000 customers all over the world.

We have R&D team to develop new products and new separating technology for ourselves. We also have quality controlling system to ensure our products. At present our main products are made of PSF/PP/PVDF. We have hollow fiber membranes and flat sheet membranes for MBR systems. So we can meet different requirements for wastewater treatment and water purification.
