Dual-Stage RO + EDI Ultrapure Water Production System

Ⅰ. A High-Purity Water Production and Extraction Equipment Description:

 Using mature, reliable, advanced, high degree of automation of the two reverse osmosis + EDI + fine mixed bed desalination water treatment process, to ensure that the quality of the treated ultrapure water to ensure that the resistivity of the treated water to reach 18.2MΩ.cm, high-purity water production and extraction of equipment, key equipment and consumables with the international mainstream of advanced and reliable products, the use of PLC + touch-screen control, the full set of system automation to a high degree, high system stability. High degree of automation of the whole system and high stability of the system.

Ⅱ. High Purity Water Extraction Equipment Water Requirements:

1, water supply: city water, water quality indicators in line with national health standards for drinking water, water supply pressure: 0.2Mpa ~ 0.4Mpa.

2, power supply: AC220V/380V, with good grounding protection.

3、Installation site: the ground is flat and has waterproof measures, there is a smooth drain, floor drains, it is recommended not to be higher than the ground

4、Environment: temperature 5-40 ℃, humidity <85% RH, no dust and strong electromagnetic interference.

Ⅲ. High Purity Water Production Equipment Process:

1. Pretreatment - reverse osmosis - purified water tank - ion exchanger - ultraviolet lamp - water point.

2. Pre-treatment-primary reverse osmosis-secondary reverse osmosis-purified water tank-ultraviolet lamp-water point.

3. Pre-treatment-reverse osmosis-intermediate water tank-intermediate water pump-EDI device-purified water tank-ultraviolet lamp-water point.

4. Pre-treatment→Ultraviolet sterilization device → primary RO device → secondary RO device → intermediate water tank → EDI device → polished mixed bed → water point.

Ⅳ. High-Purity Water Production Equipment Performance Characteristics:

1. The equipment is directly connected to the tap water made of ultrapure water, simple and convenient installation;

2. Using precision instruments, accurate online display of water quality;

3. Full automatic operation control, automatic start and stop, realize unattended;

4. With no water protection, pressure protection and other safety self-locking devices;

5. The equipment host integrated structure, covers an area of small;

6. The main components are imported products, durable, stable performance;

7. Intelligent balance system to ensure the stability and safety of equipment operation.

Ⅴ. The Application of High-Purity Water Extraction Equipment:

1. Power plant chemical water treatment;

2. Electronics, semiconductor, precision machinery industry ultrapure water;

3. Food, beverage, drinking water preparation;

4. Small pure water station, group drinking water;

5. Domestic and foreign brands of automatic biochemical analyzer water;

6. Test and analysis, reagent dispensing, laboratory testing, microbial culture, container cleaning water.

Ⅵ. The advantages of high purity water production equipment:

1. No need for acid and alkali regeneration: in the mixed bed resin needs to be regenerated with chemicals acid and alkali, need to be stored safely, regeneration of a large number of harmful wastewater and waste to be disposed of, increasing the environmental protection and safety aspects of the work.

2. Continuous and simple operation: in the mixed bed due to each regeneration and water quality changes, so that the operation process becomes complex. The EDI water production process is stable and continuous, the quality of produced water to make constant, no complex operating procedures operation is greatly simplified.
