RO system

Pure water in such industries as electronics, medicine and food, etc; purification and preparation for water used in textile industry and chemical industry; purification and preparation for water used in food and drinks and enological process; concentration and recovery of the useful materials of aqueous solution in industrial production; preliminary desalination processing of high pressure boiler make-up water of the enterprises, such as electrical power plant, etc.; brackish water and seawater desalinization; as the first class desalinating equipment for high purity water production.

RO + EDI system

EDI equipment belongs to fine treatment water system and usually used in cooperation with reverse osmose (RO) to constitute the ultrapure water treatment system with pretreatment, reverse osmose and EDI devices. EDI equipment replaced the mixed ion-exchange unit used in traditional water treatment technology. EDI equipment requires the electrical resistivity of the water to reach 0.025-0.5MΩ·cm and the reverse osmosis device can completely meet the requirements. EDI equipment can produce ultrapure water with the electrical resistivity above 15MΩ·cm.

The Water system in pharma & medical industry adopts the most advanced fully automatic two-stage RO reverse osmosis purified water treatment technology, and is used in conjunction with the pre-treatment. It uses the principle of reverse osmosis to effectively remove various salts and impurities in the water, and uses EDI electrodeionization equipment to further Improve water quality; the system has the advantages of advanced technology, stable water quality, simple operation, low operating cost, green environmental protection, no pollution, and convenient maintenance.

Process flow of water system in pharma industry

Raw water - Raw water tank - Raw water pump - Multi-media filter - Carbon filter - Water softener - Security filter - Primary RO system - Primary RO water tank (PH adjustment device) - Secondary RO system —— Secondary pure water tank——purified water pump (ozone sterilization system)——ultraviolet sterilization——0.22μm microfiltration——purified water water point

Purified water equipment function

1. Raw water tank: It stores the raw water of the system, plays a role in regulating the influent water, and also plays a certain role in precipitation of impurities in the influent water.

2. Sand filter: Preliminarily remove sediment, impurities, suspended solids and other particles in the water to reduce the turbidity of the water.

3. Carbon filter: Use the adsorption principle of carbon to absorb different colors, odors, residual chlorine, etc. in water.

4. Security filter: prevent large particles of impurities from entering the reverse osmosis membrane, causing damage to the membrane and protecting the reverse osmosis membrane.

5. Double-stage reverse osmosis host: mainly through reverse osmosis filtration to achieve the purpose of producing purified water.

6. PH adjustment system: Through PH adjustment, CO2 in the water is removed to ensure the quality of the produced water.

7. Purified water tank: store secondary reverse osmosis product water and provide water source for terminal purified water use point.

8. Ultraviolet sterilizer: kill bacteria remaining in the water to ensure the quality of the effluent.

9. Ozone sterilization system: used to clean purified water pipelines and purified water tanks.
