The ultrafiltration process is a solution separation process based on the mechanical screening principle and the pressure difference between the two sides of the membrane as the driving force. Ultrafiltration is different from all conventional filtration and micropore filtration (all are static filtration). First, the ultrafiltration separation pore size is small, and it can intercept almost all bacteria, viruses and colloidal particles, proteins, macromolecules and organic matter in the solution. The other is that the whole filtration process is carried out under dynamic conditions, and only partial separation of the solution is obtained.

Alkali-resistant tube ultrafiltration technology
Competitive advantage
Non-delamination: Using a proprietary membrane preparation process, the membrane separation material penetrates to the bottom of the entire support layer, so the membrane can be firmly embedded into the support tube to solve the separation problem between the separation layer and the support tube.
Friction resistance: A unique "peak and trough" filter inner surface structure supporting tube "peak" can protect the PVDF membrane located in the "valley" from the wear of high abrasive water, such as concentrated brine containing a large amount of mineral precipitation.
Super chemical resistance pH 1-13, filter material PVDF.
Microporous membrane, filtration accuracy: 0.2um, 50nm, providing excellent filtration water quality (generally less than 0.5NTU).
Large channel, cross-flow circulation, allows high solids load without pretreatment.
Technical advantages
