Ultrafiltration equipment No pollution

Features

1. High - efficiency Filtration: Ultrafiltration equipment can effectively remove a wide range of contaminants. It can filter out suspended solids, colloids, bacteria, and macromolecular organic substances. For instance, it can remove bacteria with a diameter of 0.02 - 1μm and macromolecular organic matter such as proteins and polysaccharides. The filtration accuracy generally ranges from 0.001 - 0.1μm, ensuring high - quality filtrate.

2. Low - energy Consumption: Compared with some other water treatment methods like reverse osmosis, ultrafiltration operates at relatively low pressure. This results in lower energy consumption during the filtration process. It can achieve efficient separation with less energy input, which is cost - effective for long - term operation, especially in large - scale water treatment projects.

3. Simple Operation and Maintenance: Ultrafiltration equipment is relatively easy to operate. The process control is straightforward, and the equipment can be automated to a large extent. Maintenance mainly involves membrane cleaning and replacement. Regular backwashing can effectively remove the contaminants adsorbed on the membrane surface, and the membrane replacement process is also relatively simple, reducing the labor intensity and operation costs.

4. Good Chemical Stability: The membranes used in ultrafiltration equipment usually have good chemical stability. They can withstand the influence of a certain range of chemical substances in the feed water, such as acids, alkalis, and oxidants within the appropriate concentration range. This allows the equipment to be applied in different water quality conditions.

   Working Principle

   1.Membrane Filtration Principle: Ultrafiltration is a membrane - separation process. The ultrafiltration membrane is a semi - permeable membrane with micropores of a certain size. When the feed water passes through the membrane under a certain pressure difference, water molecules and small - molecular substances can pass through the membrane pores due to their small size, while larger - sized particles such as suspended solids, colloids, bacteria, and macromolecular organic substances are blocked by the membrane.

   2.Separation Mechanism: The separation mechanism mainly includes sieving and adsorption. Sieving is the main principle. The size of the membrane pores acts as a "sieve". Substances larger than the pore size are retained on the feed - water side, and substances smaller than the pore size can pass through. In addition, to some extent, the membrane surface may adsorb some contaminants, which also helps to improve the filtration effect. For example, the surface of the membrane may adsorb some colloidal substances through electrostatic interaction.
