Brief Introduction of EDI Ultrapure Water Equipment

(1) The structural design should be simple, reliable, and easy to disassemble and assemble.
(2) In order to facilitate the disassembly, replacement, and cleaning of parts, the design of the actuator should use standardized, universal, and systematic parts as much as possible.
(3) The inner and outer wall surfaces of the equipment.
(4) The equipment for preparing purified water should use low-carbon stainless steel or other materials that have been verified not to pollute the water quality. The equipment for preparing purified water should be cleaned regularly and the cleaning effect should be verified.
(5) The materials that come into contact with injection water must be high-quality low-carbon stainless steel or other materials that have been verified not to pollute the water quality. The equipment for preparing injection water should be cleaned regularly and the cleaning effect should be verified.
(6) The storage period of purified water should not be more than 24 hours.

EDI ultrapure water equipment process

1. Raw water tank → Raw water booster pump → Multi-media filter → Activated carbon filter → Water softener → Security filter → First-stage reverse osmosis → PH adjustment → Intermediate water tank → Second-stage reverse osmosis → Purified water tank → Sterilization system → Purified water delivery pump → Ultraviolet sterilizer → Microporous filter → Water point
2. Raw water tank → Raw water booster pump → Multi-media filter → Activated carbon filter → Water softener → Security filter → First-stage reverse osmosis → PH adjustment → Intermediate water tank → Second-stage reverse osmosis → Pure water tank → Intermediate water pump → EDI system → Purified water tank → Sterilization system → Purified water delivery pump → Ultraviolet sterilizer → Microporous filter → Water point

Technical characteristics of EDI ultrapure water equipment

1. The system adopts full automatic control (manual control is also possible), and the automatic backwash and regeneration programs can be set when the system is running;
2. The first-level reverse osmosis and the second-level reverse osmosis are equipped with return pipes, and the reverse osmosis equipment is equipped with chemical cleaning devices and disinfection devices;
3. A PH adjustment device is installed between the first-level reverse osmosis and the second-level reverse osmosis to ensure that the conductivity of the equipment's water meets the requirements of the pharmacopoeia; 4. The second-level reverse osmosis membrane adopts a positively charged anti-pollution reverse osmosis membrane to ensure that the reverse osmosis equipment can operate stably for a long time;
5. The first-level reverse osmosis pipeline is made of 304 stainless steel, and the second-level reverse osmosis is made of 316L stainless steel;
6. Online conductivity detection instruments are installed in the first-level reverse osmosis and the second-level reverse osmosis equipment, and the conductivity of the produced water can be viewed at any time; 7. A low-pressure protection switch is installed before the first-level reverse osmosis, and a low-pressure protection and high-pressure protection switch are installed before the second-level reverse osmosis;
8. The recovery rate of the first-level and second-level reverse osmosis water can be adjusted, the recovery rate of the first-level reverse osmosis is 60%-65%, and the recovery rate of the second-level reverse osmosis is 70%; 9. All pre-treatment devices are imported original parts; the pipelines between pre-treatment equipment are made of UPVC pipes.
10. The purified water storage tank is equipped with a breathing filter, and the delivery pipeline is equipped with an ultraviolet sterilizer and a microporous filter to ensure that the pure water meets the hygiene requirements.
