1. Ultrafiltration membrane:

In membrane separation technology, the pore size of the membrane is 20 × 10^-10m~1000×10^-10The filtration membrane between m is called ultrafiltration membrane, which is between 0.002-0.1 μ m. Generally, the volume of colloids is ≥ 0.1 μ m, latex is ≥ 0.5 μ m, bacteria such as Escherichia coli and Staphylococcus have a volume of ≥ 0.2 μ m, and suspended solids and particles have a volume of ≥ 5 μ m. Therefore, ultrafiltration membrane can filter out large molecular substances such as bacteria, colloids, suspended solids, proteins, etc. in solution.

2. Process flowchart:

Suitable for drinking mineral water, mountain spring water, industrial ultrafiltration water, and can also be used for pre-treatment of purified water equipment.

3. Application of ultrafiltration:

Ultrafiltration is commonly used to produce mineral water and mountain spring water. It is a process that uses pressure as a driving force to separate impurities in liquids using ultrafiltration membranes with different pore sizes. At present, polysulfone and polypropylene hollow fiber are the most commonly used components in the water treatment industry.
