4、Product function description:

1. PE source water tank:

PE water tank uses imported PE plastic raw materials, adopts rotation (rotary molding) technology with international advanced level, combines with the needs of users, and strictly controls the quality. It produces water storage tank with full range of specifications and beautiful shape, with the maximum capacity of 100 cubic meters. Weng Xianjun also undertakes the production, research and development of various special-shaped rotational molding products and various rotational molding machines, Hot box machine, mold development and development, and provide external technical services. All kinds of plastic products produced by our company are beautiful, non-toxic, tasteless, acid resistant, alkali resistant, impact resistant, high-temperature resistant, cold resistant, not easy to aging, easy to install and transport, widely used in construction water, water treatment, medicine and food, electronics, chemical industry, aquaculture, textile printing and dyeing and many other industries. 　

2. Mechanical filter:

It is mainly used to remove rust, sediment, algae, suspended solids and other impurities in the water, reduce the turbidity of water, make the turbidity of effluent less than 0.5ntu, CODMn less than 1.5mg/l, iron content less than 0.05mg/l, SDI ≤ 5. The control valve can be used for backwashing and forward washing at any time to wash off the dirt on its surface, prevent its blockage and restore its filtration capacity.

3. Activated carbon filter:

Activated carbon has a strong adsorption and filtration performance, and has a strong adsorption effect on residual chlorine, heterochromatic, peculiar smell and organic matter in water. As the reverse osmosis membrane is very sensitive to residual chlorine and organic matter, activated carbon must be configured to absorb residual chlorine and organic matter, so that the residual chlorine in the effluent is less than 0.1mg/l, and SDI is less than 4. Firstly, it can meet the water supply requirements of reverse osmosis membrane. Second, it can greatly improve the original taste of the source water. It can be backwashed at any time through the multi-channel control valve or steam butterfly valve to wash off the colloid and other pollutants on the surface, prevent the surface of activated carbon from being surrounded by impurities, and prevent its blockage, and restore its treatment capacity.

4. Security filter:

After pretreatment, a security filter is installed in front of the high-pressure pump to prevent impurities larger than 1um from entering the high-pressure pump and damaging the high-pressure pump and reverse osmosis membrane. The PP filter core with loose outside and tight inside (with framework and good strength) is adopted. The water is filtered from outside to inside, which can prolong the time of filter core being blocked. The upper part has an exhaust valve, which can prevent air from entering the pump and damaging the pump; the lower part has a drain valve, which can discharge the retained impurities at any time.

5. Reverse osmosis device:

Reverse osmosis technology is a mature desalination technology in the world at present, and it is also a kind of water treatment process widely used in the market. It can precisely filter out bacteria, viruses, metal ions, salts, pesticides and various carcinogens in water. Its working pressure is low, water production is large, desalination rate is high, and it is easy to maintain. The design of automatic washing device can prolong its service life. The design of automatic flushing device can prolong its service life.

6. Ultra pure water equipment (EDI device for electric desalting)

EDI electric desalting device is used to produce ultra pure water and secondary desalting equipment after reverse osmosis equipment, which can produce up to 10-18.2m Ω / cm. Therefore, it is widely used in microelectronics industry, semiconductor industry, solar photovoltaic industry, fine chemical industry and power generation industry, pharmaceutical industry and laboratory. It can also be used as pharmaceutical distilled water, food and beverage production water, boiler make-up water of power plant, and other applications of ultra-high purity water.

7. PH regulating device:

As the water produced by reverse osmosis is slightly acidic, and the pH value after secondary reverse osmosis is small, in order to meet the process requirements, and at the same time, the influent water of the membrane element is required to be neutral, which is of great benefit to the long-term stable operation of the secondary reverse osmosis membrane, desalination rate and water production. Therefore, it is necessary to adjust the pH of feed water to neutral before the secondary RO membrane. The automatic dosing system adopts German aldoux or American Milton Luo metering pump, which is accurate and reliable. The dosage is about 2-5ppm.

8. Pure water tank:

The product is made of SUS304 stainless steel plate, which is beautiful, economical and practical, and the main body is durable. Compared with other water tanks, stainless steel water tanks have many advantages, such as beautiful appearance, light weight, high strength, corrosion resistance, high temperature resistance, clean water quality, anti-seepage, anti-seismic, never growing moss, no secondary pollution of water quality, convenient installation, no maintenance and easy cleaning.
