1、 Equipment Name: Fully Automatic Softening Reverse Osmosis+EDI Ultra Pure Water Equipment

2、 Specification and model: HDNRO+EDI-5000L

3、 Equipment brand: Wenzhou Heideneng - WZHDN

4、 Product Function Description:

1. Mechanical filter:

Mainly used to remove impurities such as rust, sediment, algae, suspended solids, etc. from water, reduce water turbidity, and make the effluent turbidity less than 0.5NTU, CODMN less than 1.5mg/L, iron content less than 0.05mg/L, SDI ≤ 5. It can be backwashed or backwashed at any time by controlling the valve to flush out the dirt on its surface, prevent blockage, and restore its filtering ability.

2. Activated carbon filter:

Activated carbon has extremely strong adsorption and filtration performance, and has a strong adsorption effect on residual chlorine, discoloration, odor, organic matter, etc. in water. Due to the high sensitivity of reverse osmosis membranes to residual chlorine and organic matter, activated carbon must be configured to adsorb residual chlorine and organic matter, with residual chlorine in the effluent ≤ 0.1mg/L and SDI ≤ 4, which can meet the water supply requirements of reverse osmosis membranes. The second can greatly improve the original taste of the source water. It can be backwashed at any time through a multi way control valve or a pneumatic butterfly valve to wash away the colloidal and other pollutants on its surface, prevent the activated carbon surface from being surrounded by impurities and unable to adsorb, and prevent it from clogging, restoring its processing capacity.

3. Softener:

The hardness of water is mainly composed of cations such as calcium (Ca) and magnesium (Mg) ions. When raw water containing hardness passes through the cation resin layer of the water softener, calcium and magnesium ions in the water are adsorbed by the resin, while sodium ions are released. The water flowing out of the exchanger in this way is softened water that has removed hardness ions. When the resin that adsorbs calcium and magnesium ions reaches a certain level and loses its exchange capacity, the water softener automatically regenerates the failed resin according to the predetermined program, using a higher concentration of sodium chloride solution to pass through the resin and restore the failed resin to a sodium type resin.

4. Security filter:

After pre-processing, a security filter is installed before the high-pressure pump to prevent impurities larger than 1UM from entering the pump and damaging the high-pressure pump and reverse osmosis membrane. Adopting an externally loose and internally tight PP filter element (with a skeleton and good strength), water is filtered from the outside to the inside, which can prolong the time when the filter element is clogged. The upper part has an exhaust valve to prevent air from entering the pump and damaging it, while the lower part has a drain valve to discharge trapped impurities at any time.

5. Reverse osmosis device:

Reverse osmosis technology is currently a mature desalination technology internationally, and it is also a widely used and applicable water treatment process in the market. It can precisely filter out bacteria, viruses, metal ions, salts, pesticides, and various carcinogens in water. It has low working pressure, large water production, high desalination rate, and is easy to maintain. The design of an automatic flushing device can extend its service life. Designing an automatic flushing device can extend its service life.

6. Terminal filter:

By using a microporous membrane with an absolute pore size of 0.22um, microorganisms and their heat sources can be completely removed, ensuring sterile water supply and meeting pharmaceutical water requirements

7. Ultra pure water equipment (electric desalination EDI device):

The EDI electric desalination device, as a device for producing ultrapure water and a secondary desalination device after reverse osmosis equipment, can produce up to 10-18.2 M Ω/cm. Therefore, it is widely used in the microelectronics industry, semiconductor industry, solar photovoltaic industry, fine chemical and power generation industry, pharmaceutical industry, and laboratories. It can also be used as distilled water for pharmaceuticals, water for food and beverage production, feed water for boilers in power plants, and other applications of ultra-high purity water.

Five. Local features:
RO membrane automatic and manual operation/flushing, optional touch screen control, human-machine interface.
The RO membrane can be manually cleaned with chemical agents inside the machine
◇ Pure water high water level automatic shutdown, low water level automatic startup

Multi stage high-pressure pump with water shortage protection and overload/overvoltage protection

◇ Voltage loss, undervoltage, overcurrent, short circuit, open circuit, leakage protection

The equipment is made entirely of stainless steel and operates automatically without the need for manual labor.

Electronics, electroplating, electrophoresis, batteries, vacuum coating, dishwashing detergent, cosmetics, adhesives, chemicals, pigments, surface treatment, brackish water treatment, etc.

And it can be applied as follows:

The RO pure water device, as the pre desalination equipment for ultra high purity water production, combined with the EDI device, has become an excellent combination of ultra pure deionization equipment.

The electronic industry uses water to wash electronic components such as integrated circuits, silicon chips, display tubes, and PCBs.

The pharmaceutical industry uses large amounts of water for infusion, injections, tablets, biochemical products, equipment cleaning, etc;

Other processes use pure water for water, motorcycle parts, home appliance coating, coated glass, cosmetics, fine chemicals, etc.
