Kunming water ultrafiltration equipment ultrafiltration water purifiers ultrafiltration unit ultrafiltration system

Ultrafiltration process liquid - Tank - pressure pump - Ultrafilter - hollow ultrafiltration equipment - tank - backwash water - is the use of ultrafiltration backwash pump interception capabilities porous material, physical way to remove water trapped impurity particles of a certain size. In a pressure driven water solution, the organic low-molecular, inorganic ions and other small size species may reach the other side of the membrane through the fiber wall micropores, bacterial solution, colloid, particulate matter, and other large organic molecules It can not pass through the fiber wall material is retained, so as to achieve the purpose of screening the solution of different components. The process is operating at room temperature, no phase change, and no secondary pollution. . No phase transformation during ultrafiltration, room temperature operation, the separation is particularly suitable for heat-sensitive material, and has good heat resistance, acid and oxidation resistance, can be below 60 ℃, pH 2-11 under conditions of long-term continuous use. Ultrafiltration membrane structure is divided into a variety of configurations according to frame type (plate), hollow fiber, nano membrane sheet membrane, tube, roll and so on. Wherein the hollow fiber membrane is a form of ultrafiltration technology is the most mature and advanced. Hollow fiber diameter of 0.4-2.0mm, inner diameter 0.3-1.4mm, the wall covered with porous hollow fiber, pore size in order to retain the molecular weight of the material expression, molecular weight cutoff up to several thousand to hundreds of thousands. Raw water in the outer or inner chamber pressure hollow fiber flow, respectively, constitute the external pressure and internal pressure hollow membrane. Ultrafiltration is a dynamic filtering process, are retained material can be ruled out with the concentrate without clogging the membrane surface, long-term continuous operation. Applications membrane technology has been very extensive, including the food industry, beverage industry, dairy industry, bio-fermentation, bio-medicine, pharmaceutical chemicals, biological agents, Chinese medicine, clinical medicine, wastewater, food industrial wastewater treatment, recycling and environmental engineering, and so on.
