Plastic cleaning sewage treatment equipment
1, mechanical filter
Mechanical filter is a pressure vessel filled with a specified thickness of filter media, when filled with a single filter media for the single-layer mechanical filter, filled with different types of filter media for the double-layer or multi-media filter.
Function: in the water quality pretreatment system, multi-media filter pressure vessel filled with quartz sand of different particle sizes according to a certain gradation, the flocculated raw water under a certain pressure from top to bottom through the filter media layer, so that the suspended matter in the water can be retained and removed, multi-media filter can effectively remove the suspended matter in the raw water, fine particles, full-valent iron and colloid, bacteria and algae, and organic matter. Its water SDI15 (pollution index) is less than or equal to 5, fully able to meet the reverse osmosis device feed water requirements.

2, reverse osmosis equipment
Reverse osmosis is one of the most widely used membrane separation process, the use of pressure to make the water through the membrane, while the soluble salts, colloids, organisms and microorganisms are trapped on the surface of the membrane, and discharged with the concentrated water. It can effectively remove all organic matter and 90%~99% of ions.
Reverse osmosis is a modern new pure water treatment technology. Through the reverse osmosis element to improve the purity of water, remove impurities and salt contained in the water. The pure water we drink every day is treated with reverse osmosis equipment for crystal clear water.

3, ultrafiltration equipment
Ultrafiltration is between microfiltration and nanofiltration, and there is no obvious dividing line between the three. Generally speaking, the pore size of ultrafiltration membrane is between 0.05 um-1 nm, and the operating pressure is 0.1-0.5 Mpa. It is mainly used to intercept and remove the large molecules such as suspended solids, colloids, particles, bacteria and viruses in water
◆Mineral water: In the manufacture of mineral water, the application of ultrafiltration technology, in the design of the project. The ultrafiltration design will be designed according to the water quality analysis report of the mineral water source, targeted selection of the pore size of the membrane and the type of membrane.
◆Foodstuffs: ultrafiltration technology is gradually adopted in the production of dairy products, fruit juice, wine, condiments and other foodstuffs, such as the separation of protein and low-molecular-weight lactose from water in milk or whey, the clarification and decontamination and disinfection of fruit juice, the removal of colored proteins, polysaccharides and other colloidal impurities in wine, etc., and the removal of bacteria in soy sauce and vinegar, which shows the advantages of economy, reliability, and quality assurance compared with the traditional methods.
