1. Ultrafiltration membrane principle

Uf filter membrane is the whole process of screening using membrane separation equipment. The pressure difference on both sides of the membrane is used as the driving force, and the membrane is used as the filter material. Under a certain working pressure, when the raw liquid passes through the membrane surface, the uf filter membrane Many microplates filled on the surface only allow water and small molecular water chemical substances to pass through, while the organic matter whose volume exceeds the microdiameter of the membrane surface is intercepted to the leakage side of the membrane and becomes the extraction liquid, thereby achieving purification, separation and shrinkage. Purpose.

The wall thickness of filament of uf filter membrane per meter is about 6 billion times of 0.01μm microporous plate, its diameter only allows water, favorable minerals and nutrients in water, and the minimum size of pathogenic bacteria is more than 0.02μm. The colloidal solution, rust, floating solids, fine sand, and biological macromolecular substances with large volume of pathogenic bacteria can be cut off.

2.The working process of uf filter membrane

①. Water first goes to tube of uf filter membrane. Under the action of the pressure difference, many 0.01μm microplates covered on the membrane surface only allow water, beneficial minerals and nutrients to pass through and become filtered water. However, harmful substances such as bacteria, rust, colloidal solution, fine sand, suspended solids, biological macromolecular substances are blocked and discharged during cleaning.

②. After a period of use, the blocked bacteria, rust, colloidal solution, suspended solids, biological macromolecular substances and other harmful substances will depend on the inner surface of the ro uf membrane, which will gradually reduce the water production, especially when drinking When the water environment is seriously polluted, it is more likely to cause blockage, and regular cleaning can effectively restore the water production of the membrane.

③. The filter element is composed of ABS shell and ro uf membrane filaments synthesized by epoxy resin shell on both sides of the shell. The epoxy shell fills the gap between the membrane filament and the membrane filament, creating protection between the original liquid and the permeate. The stock solution first enters the pore wall and becomes the permeate after filtration, so as to avoid the stock solution directly entering the permeate without being filtered.
