Ultrafiltration Membrane System Drinking Water Purification Machine

Ultrafiltration is a kind of membrane separation technology between nanofiltration and microfiltration. Ultrafiltration uses a pressure-active membrane to trap colloids, particles and relatively high molecular weight substances in water under the action of external driving force (pressure), while water molecules and small solute particles pass through the membrane separation process. The material with molecular weight of 500-500000 Dalton can be intercepted by screening through micropores on the membrane surface. When the treated water passes through the membrane surface at a certain flow rate with the help of external pressure, water molecules and solutes with molecular weight less than 300-500 pass through the membrane, and particles and macromolecules larger than the membrane pores are intercepted due to the screening effect, so that the water is purified. That is to say, when the water passes through the ultrafiltration membrane, most of the colloidal silicon contained in the water can be removed, and a large amount of organic matter can be removed, so as to achieve the purpose of purification, separation and concentration of the stock solution.;

1. The separation process does not involve phase changes, with low-pressure pumps serving as the driving force, resulting in minimal energy consumption.

2. Separation can occur at room temperature, making it suitable for heat-sensitive substances.

3. The equipment and process design are simple, facilitating operation, management, and maintenance.

4. The effective membrane area per unit volume is large, ensuring high work efficiency and a reduced footprint.
