The core component of ultra pure water system equipment is the reverse osmosis membrane component, which is usually composed of a pre-treatment part, a reverse osmosis host part, and a subsequent deepening treatment part.
1. The pre-treatment is composed of quartz sand filter, activated carbon filter, water softener (optional), precision filter (our company adopts fully automatic control valve head with automatic control valve), and ultrafiltration system can also be used as pre-treatment, but the project cost is usually high. The main purpose of pre-treatment is to remove sediment, rust, colloidal substances, suspended solids, chromaticity, odor, and biochemical organic matter contained in the raw water. When the hardness of the raw water is high, a fully automatic water softener can be selected, which effectively protects the reverse osmosis membrane and extends its service life.
2. The reverse osmosis host mainly consists of a high-pressure pump, membrane shell, imported reverse osmosis membrane components, online instruments, control electrical, etc. As long as the number of membranes and pump model selection are appropriate, the desalination rate and water yield of the reverse osmosis host can reach the rated indicators, and the effluent conductivity can be guaranteed to be ≤ 10us Below CM, (raw water conductivity less than 500us/cm, working temperature: 1-40 ℃)
3. The subsequent deepening treatment part refers to further deepening treatment on the basis of pure water produced by reverse osmosis to produce ultra-pure water, usually using ion exchange mixed bed equipment or EDI equipment. According to customer requirements, the water resistance can reach 18.2M Ω. CM. If it is applied to direct drinking water technology, a sterilization device can be added, usually an ultraviolet sterilizer or ozone generator, to ensure that the produced water meets the standard for direct drinking.

The processes of ultra pure water equipment can be roughly divided into the following categories:
Process comparison and selection
1. Pretreatment system → Reverse osmosis system → Intermediate water tank → Coarse mixed bed → Fine mixed bed → Pure water tank → Pure water pump → Polishing mixed bed → UV sterilizer → 0.2 or 0.5 μ M precision filter → water object (≥ 18M Ω. CM) (traditional process).
2. Pretreatment system → Reverse osmosis system → Intermediate water tank → Water pump → EDI device → Purified water tank → Pure water pump → Polishing mixed bed → UV sterilizer → 0.2 or 0.5 μ M precision filter → water object (≥ 18M Ω. CM) (latest process).
3. Pretreatment system → Primary reverse osmosis system → Dosing machine (pH regulation) → Intermediate water tank → Second stage reverse osmosis (positively charged reverse osmosis membrane) → Pure water tank → Pure water pump → EDI device → UV sterilizer → 0.2 or 0.5 μ M precision filter → water object (≥ 17M Ω. CM) (latest process).
4. Pretreatment system → Reverse osmosis system → Intermediate water tank → Water pump → EDI device → Ultra pure water tank → Ultra pure water pump → UV sterilizer → 0.2 or 0.5 μ M precision filter → water object (≥ 15M Ω. CM) (latest process).
5. Pretreatment system → reverse osmosis system → intermediate water tank → pure water pump → coarse mixed bed → fine mixed bed → ultraviolet sterilizer → precision filter → water object (≥ 15M Ω. CM) (traditional process)
Each of the above processes has its own advantages, and you can choose a suitable process based on your own situation. With the development of science, many new processes have replaced old ones. The use of reverse osmosis+EDI technology to produce high-purity water has become popular and the most advanced technology.
