Don t know which industrial small EDI pure water treatment equipment brand is better?

The EID system, also known as the electric regeneration mixed bed system, is based on the principle of using the voltage of the membrane blocks at both ends to move the charged particles in the water, and on the basis of the selective resin film and ion exchange resin, the ion movement can be accelerated, and finally the effect of water purification can be achieved.

Explain the basic introduction of the complete set of water treatment equipment for EID:

The water treatment principle of the EID water treatment system is that the hydrogen (H+) and hydroxide (OH-) required for the regeneration of ion exchange resin are mainly supplied by dissociation in water under high voltage, and this water treatment process can achieve no need to use acid and alkali agents for regeneration and reduction, and there will be no secondary pollution.

EID complete set of water treatment equipment has requirements for the treatment of raw water, raw water requirements need to reach hardness <1mg L as CaCO3 silicon <1mg L, TOC

Residual chlorine <, TEA (with CO2) < 25 mg L as CaCO3 pH 5-9.

Pure water equipmentIt is suitable for chips in the electronics industry, semiconductors, biochemical products in the pharmaceutical industry, water for the imaging control process, medical laboratories, laboratory water and other fields that require high-purity water.

For small laboratory EDI ultrapure water equipment, the mixed-bed ion exchange water treatment process can be used, and the water resistivity of the raw water can be reached after treatment.

The advantages and characteristics of the complete set of EID water treatment equipment are as follows:

1. It can realize 24-hour uninterrupted water supply, using continuous operation and regeneration;

2. The water treatment efficiency of the equipment is high, and the effluent quality is stable;

3. You can choose to use manual or automatic mode of system;

4. There will be no secondary pollution, mainly because the equipment does not need to use water treatment agents;

5. Low operating cost and simple operation;

Guangzhou Duoqing Environmental Protection Technology Co., Ltd. has developed a micro-small EDI membrane block, and has developed a laboratory and industrial micro-EDI ultra-pure water machine according to the design of the micro-EDI membrane block, with dimensions and specifications of 60 60 135cm, covering a relatively small area, and producing water quality of 18 trillion ohms. Water production 10l h 150l h.

(1) Industrial manufacturing.

Industrial industries that require ultrapure water mainly include electronics, electric power, petrochemical industry, etc. In the electronics industry, semiconductors, integrated circuit chips and packaging, liquid crystal displays, high-precision circuit boards, optoelectronic devices, microelectronics industry, large-scale and ultra-large-scale integrated circuits need to be cleaned with a large amount of ultrapure water for finished and semi-finished products. In power production, the power generation cycle efficiency of the power generation system depends on the temperature and pressure of the water vapor in the system, and contaminants such as sodium, chloride or silica can easily cause corrosion and contamination of turbine blades.

In the petrochemical industry, high-purity water is mainly used in oilfield injection water, chemical reaction cooling water, chemical agents, chemical fertilizers and fine processing, cosmetics manufacturing, cleaning water in the electroplating industry, and solvent water in the battery industry.

2) Consumer goods industry.

Ultrapure water is mainly used in the food and pharmaceutical industries. With the intensification of environmental pollution and the continuous improvement of people's health requirements, the water quality requirements of the food and beverage industry have also increased, and high-purity water has been more and more widely used in the food and beverage industry, such as drinking pure water, beverages, wine and other production water, aseptic filling of beverages, transportation and cleaning of raw materials, high-pressure cleaning of workplaces and equipment, etc.

Medicine plays a vital role in people's lives, and the quality of medical water directly affects the best level and is related to the life safety of patients. As early as 1990, the second part of the Pharmacopoeia of the People's Republic of China published in China stipulated the requirements for three types of medical water, including medical distilled water, water for injection and sterile water for injection, and stipulated eleven indicators: pH, chloride, nitrate and nitrite, sulfate, calcium salt, nitrogen, carbon dioxide, easily oxidizing substances, non-volatile substances, heavy metals and heat sources.

It can be seen that ultrapure water is important in the pharmaceutical industry.

3) Laboratory water.

In the basic research of life sciences and medical engineering, as well as in the clinical, pharmaceutical, physiology, biochemical, chemical, physical fields of the hospital, the use of ultrapure water, cell or tissue culture, IVF, hospital laboratory analysis, preparation of various injections and pharmaceutical dilution water directly or indirectly.

EDI ultrapure water equipment is a water treatment equipment that uses pretreatment, reverse osmosis technology, mixed bed, EDI device and post-stage treatment to remove the conductive medium in the water almost completely, and remove the colloidal substances, gases and organic substances that do not dissociate in the water to a very low level, and the effluent resistivity can reach megaohms.
