Reinforced Ultra Filtration for Ground Water Purification with 0.03um pore size

Ultrafiltration (UF) is a membrane filtration process using pressure as a driving force to remove a large majority of contaminants including particulate matter, bacteria, viruses, and high molecular substances from water or process feed streams. Depending on the pore size of the UF membrane and the size of the particles suspended in the feed water, certain particles will pass through the membrane (typically low molecular weight solutes and dissolved solids) while others are rejected (e.g. suspended solids, bacteria, viruses, and high molecular weight substances). This separation process is widely used in water treatment, industry, and research for purification and concentration of solutions. Ultrafiltration is not fundamentally different from microfiltration, except in terms of the size of the molecules it retains. The basic process of membrane filtration is shown in Figure 1. The process is pressure driven and typically operates with a feed pump, pushing the water through the membrane.

The filtration spectrum and the selectivity of various filtration methods are shown in Figure 2. Because UF membranes reject particles based on size exclusion principles, they are often classified according to the size of the separated components. UF membranes may be classified by molecular weight cutoff (MWCO) in Daltons (1 Dalton is equivalent to 1 atomic mass unit) or by pore size (the nominal diameter of the openings or micro pores) in microns. The MWCO of the membrane refers to the molecular weight (in Daltons) of the molecule or solute that is 90% retained by the membrane. Typically, UF membranes are classified by a range from about 1,000 to 500,000 Daltons (Da). But as the membrane becomes more open (greater than 100,000 Da), it is common to see UF membranes classified by pore size.

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.
