Folded Cartridge Cross-Flow Filter Assembly

Cross-flow filtration needs to be pointed out that in the case of microfiltration, if the processing capacity is relatively large, the microfiltration device must be in the form of a 'cross-flow' design. Otherwise, the microporous membrane is easily affected by the liquid in the treatment liquid. Particles and colloids are blocked, thereby shortening the service life of the filter membrane. Since the sediment is continuously swept away by the lateral flow of the treatment liquid and keeps swimming around, it is not easy to cover the membrane surface, so it will not affect the passage of the filtrate. Plate-and-frame microfiltration devices are the same as reverse osmosis and ultrafiltration. The components of microfiltration also have various structures such as plate-and-frame, tubular, spiral and hollow fiber types. The effective diameters of plate-and-frame microfiltration devices are generally 13mm and 25mm in diameter. , 47mm, 90mm, 142mm and 293mm, etc. Most of them are made of stainless steel or engineering plastics. For microfiltration devices that require larger processing capacity. Multi-layer plate and frame filter presses can be used. It is increased from Starting from the membrane area. The microfiltration multi-layers are assembled in parallel or in series. The pleated cartridge filter assembly is used for the filtration of a large amount of liquid. A pleated cartridge filter device can be used, which is characterized by a large membrane area per unit volume. Therefore, filtration High efficiency. Syringe filter Syringe filter is a kind of micro filter installed between the syringe barrel and the needle, with a microporous membrane as the filter medium. The syringe filter can be used for a small amount of fluid (gas, liquid) filtration Purification to remove particles and bacteria, or used for the determination of bacteria and particles. Often used for aseptic processing of intravenous fluids. During operation, it is used to advance the injection syringe to achieve the purpose of filtration.
