1、 Equipment name: Automatic reverse osmosis +EDI ultra-pure water equipment with 10 tons of water tank

2、 Specifications and models：HDNRO+EDI-6000L

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product function description:

1. 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.

2. Sterile water tank:

As a aseptic tank unit, a sterile can connects the ultra-high temperature equipment and the packaging equipment. The aseptic time of aseptic tank is longer than the production time, which not only ensures the product quality of continuous production, but also avoids reheating of products due to production stop or overload of packaging line. Another advantage is that the sterilized intermediate storage tank of sterile products ensures that subsequent production can be carried out even in CIP.

3. 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.

4. Terminal filter:

The microorganism and heat source can be completely removed by using microporous filter membrane with absolute pore diameter of 0.22um, which can ensure the sterile water supply and meet the requirements of pharmaceutical water

5. 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.

6. 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. 　

Five. Features of the machine:
◇ Automatic and manual operation / washing of RO membrane, optional touch screen control and man-machine interface;
◇ The RO membrane can be cleaned by manual chemical medicine in the machine;
◇ High water level automatic shutdown, low water level automatic start-up;

◇ Water shortage protection and overload and over-voltage protection of multi-stage high-pressure pump;

◇ Loss of voltage, under voltage, over-current, short circuit, open circuit, leakage protection;

◇ The equipment is made of stainless steel and operates automatically without manual operation.

Electronics, electroplating, electrophoresis, battery, vacuum coating, detergent, cosmetics, glue, chemical industry, pigment, surface treatment, brackish water treatment, etc.

It can be applied as follows:

◇ RO pure water device, as the former desalting equipment for ultra-high purity water production, and EDI device, has become the excellent combination of ultra pure deionization equipment;

◇ Electronic industry water integrated circuit, silicon chip, display tube and other electronic components, PCB washing;

◇ Water infusion, injection, tablet, biochemical products, equipment cleaning, etc;

◇ Ultra pure water for other processes such as water motorcycle auto parts, home appliance coating, coated glass, cosmetics, fine chemicals, etc.
