The production process of silica sol is a process with large energy consumption and long cycle. In the conventional concentration method, the dehydration method is usually selected for dehydration, so that the desired concentration of silica sol can be obtained. Ultrafiltration concentration method can reduce product cost, improve product quality, improve product quality, and also improve product development efficiency and product quality.
Ultrafiltration is a more advanced method for preparing silica sol. Ultrafiltration is the use of ultrafilters for concentration. Unlike filters, ultrafiltration membranes only allow moisture and soluble salts to pass through, but not sol particles. Obviously, this method is very useful, it can not only remove the water in the dilute sol, but also can remove a small amount of ions and soluble substances.
However, the ultrafiltration membrane does not allow filter cake or precipitation, so ultrafiltration must be carried out under continuous stirring. Whether ultrafiltration can be carried out according to the intended purpose, the key is to have a suitable ultrafiltration membrane. Your company is based on MBR membrane bioreactor, and the product innovatively produces ultrafiltration membrane; it relies on membrane separation research technology to make breakthroughs.
