Ultrafiltration(UF)It is a membrane between microfiltration and nanofiltration, and its pore size is approximately 0.001 ～ 0.1μmThe basic principle is a sieve separation process. Under the drive of pressure difference, the solvent and small solute particles in the raw liquid pass through the membrane from the high-pressure feed liquid side to the low-pressure side. The resulting liquid is generally called the filtrate or permeate, while the large particle components are retained by the membrane, increasing their concentration in the filtrate residue, achieving the purification, separation and concentration of the solution. It can effectively remove particles, bacteria, viruses, pyrogens, colloids and high-molecular organic substances in water.

Application scope:

l Purification of various pure water and drinking water

l Separation and refinement of biochemical fermentation broth

l Separation and refinement of traditional Chinese medicine extracts

l Electrophoretic paint recycling/Electrophoresis waste liquid treatment and recycling

Ultrafiltration water treatment equipment

Hollow fiber ultrafiltrationUFUltrafiltration is a high-tech membrane separation technology. It is a solution separation process based on the principle of mechanical sieving and driven by the pressure difference on both sides of the membrane. The pore size of ultrafiltration membranes is generally within3～100㎜Between. The molecular weight that can be retained is1000～500000daltonThe substances that can be removed by the texture of ultrafiltration membranes include sugars, biomolecules, polymers, colloidal substances, etc. Ultrafiltration membranes are classified by their nominal "cutting molecular weight"MWCODescribe the aperture size. It is usually defined as the membrane having90%The above-mentioned retention rates***Small molecular weight substances. The water treatment adopts a molecular weight cut-off of10000～20000dalton.

Ultrafiltration membranes are asymmetric semi-permeable membranes made of high molecular materials through special processes. Under pressure, solutes of different molecular weights in the solution are separated, graded or concentrated through the porous and special physical and chemical structure in the membrane. It is a separation method that does not cause phase change in the solution. It can effectively remove organic matter, viruses, colloidal substances and non-ionic suspended precipitates in water.

Scope of application
