EDI small water purification equipment and technological advantages of the process configuration requirements article of injection: Small Water Purification EDI apparatus is a technical description of ultrafiltration screening for the separation principle of a pressure driving force for the membrane separation process, The filtration accuracy is within the range of 0.005-0.01um, which can effectively remove particles, colloids, bacteria and polymer organics in the water. It can be widely used in the separation, concentration and purification of substances. The ultrafiltration process has no phase inversion and has good temperature resistance, acid and alkali resistance and oxidation resistance. The ultrafiltration membrane adopts different construction forms, membrane materials and process designs, which can adapt to various water quality conditions and separation functions. In the ultrafiltration process, the deep-water liquid is driven by pressure and flows through the membrane surface. The deep agent (water) smaller than the membrane pores and the water-permeable membrane of small molecular solutes become purified liquid (filtrate). The solute group is intercepted and discharged with the water flow to become a deep shrinkage liquid. The ultrafiltration process is dynamic filtration, and the separation is completed in a flowing state. The solute is only deposited on the membrane surface in a limited way, the ultrafiltration rate decays to a certain extent and tends to balance, and can be restored by cleaning. The reverse osmosis system of a small EDI purified water treatment equipment for injection production is composed of a reverse osmosis membrane (RO), a high-pressure pump and a security filter set up to protect the reverse osmosis membrane. At present, the most commonly used permeable membrane category is polyamide membrane, and the membrane type is roll composite membrane. The salt removal rate of this type of membrane can reach 99.9%. Since the RO membrane is easily affected by the pH value, residual chlorine and water temperature in the water, the RO membrane has strict requirements on the inlet water quality before operation. Process configuration requirements for small EDI purified water treatment equipment for injection production: 1. The structure design should be simple, reliable, and easy to disassemble. 2. In order to facilitate the disassembly, replacement, and cleaning of parts, the design of the actuator adopts standardized, universal and systematic parts as far as possible. 3. The inner and outer wall surfaces of the equipment should be smooth and flat, free of dead corners, and easy to clean and sterilize. The surface of the parts should be treated with chrome plating to resist corrosion and prevent rust. Avoid using paint on the outside of the equipment to prevent peeling. 4. The small EDI purified water treatment equipment should be made of low-carbon stainless steel or other materials that have been verified to not pollute water quality. The equipment for preparing purified water should be cleaned regularly and the cleaning effect should be verified. 5. The material in contact with the product water must be high-quality low-carbon stainless steel (such as 316L stainless steel) or other materials that have been verified to not pollute the water quality. The equipment should be cleaned regularly and the cleaning effect should be verified. 6. The storage period of purified water should not be longer than 24 hours, and its storage tank should be made of stainless steel or other materials that have been proven to be non-toxic, corrosion-resistant and do not leak polluting ions. 7. The design of pressure vessel must be undertaken by a licensed unit and qualified personnel, and it must be handled in accordance with the relevant provisions of the People’s Republic of China National Standard 'Steel Pressure Vessel' (GB150-80) and 'Pressure Vessel Safety Technical Supervision Regulations' . A brief introduction to the above small EDI purified water treatment equipment.
