3、Equipment brand: Wenzhou Haideneng -WZHDN

• Four. Product function Description:　

1. Mechanical filter:

It is mainly used to remove impurities such as rust, sediment, algae and suspended solids in the water, reduce the turbidity of the water, make the turbidity of the effluent less than 0.5Ntu, CODMN less than 1.5mg/L, iron content less than 0.05mg/L, SDI≤5.Backwash and forward wash can be carried out at any time through the control valve to flush out the dirt on its surface, prevent its clogging and restore its filtration capacity.

2. Activated carbon filter:

Activated carbon has a very strong adsorption filtration performance, the remaining chlorine in the water, different color, odor, organic matter has a strong adsorption.As the reverse osmosis membrane is very sensitive to residual chlorine and organic matter, it must be configured with activated carbon to adsorb residual chlorine and organic matter, so that the effluent residual chlorine ≤0.1mg/L and SDI≤4, which can first meet the feed water requirements of the reverse osmosis membrane.The second can greatly improve the original taste of the source water.Can be at any time through multiple control valve or steam butterfly valve backwash, to wash off the surface of the colloid and other pollutants, to prevent activated carbon surface is surrounded by impurities do not play adsorption role, and prevent its blocking, restore its treatment capacity.

3. Water softener:

The hardness of water is mainly composed of cations: calcium (Ca), magnesium (Mg) ions.When raw water containing hardness passes through the resin layer of water softerer, calcium and magnesium ions in the water are absorbed by the resin and sodium ions are released at the same time.It from escaping from the exchange of water is to remove the demineralized water hardness ions, when the absorption of calcium and magnesium ions resin after reaching a certain degree, the loss of exchange capacity, water softener, in accordance with the scheduled program at this time, automatically invalidation of the resin regeneration work, with a high concentration of sodium chloride solution through resin, to restore failure of the resin to sodium to resin.

4. Security filter:

After pretreatment, a security filter is installed in front of the high-pressure pump to prevent impurity particles larger than 1UM from entering the high-pressure pump and damaging the high-pressure pump and reverse osmosis membrane.Adopt the PP filter element with loose outside and tight inside (with skeleton and good strength), and the water is filtered from outside to inside, which can prolong the blocking time of the filter element.The upper part of the exhaust valve, can prevent the air into the pump and damage the pump, the lower part of the sewage valve, can be removed at any time trapped impurities.

5. Secondary reverse osmosis device:

Reverse osmosis technology is a more mature desalination technology in the world, and is also a water treatment technology with wide market application and wide application range.It can precisely filter out bacteria, viruses, metal ions, salts, pesticides and various carcinogens in the water, with low working pressure, large water yield and high desalination rate. It is easy to maintain and design automatic washing device, which can extend its service life.The design of automatic flushing device can prolong its service life.

6. Terminal filter:

The microporous membrane with an absolute pore diameter of 0.22um can completely remove microorganisms and their heat source, ensuring the sterility of water supply and meeting the requirements of pharmaceutical water.

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

EDI electric desalination plant as equipment of producing ultrapure water, as a reverse osmosis device after secondary desalination equipment, can making out as much as 10-18.2 - M 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, water for food and beverage production, make-up water for boilers in power plants, and other applications of ultra-pure water.

Five.Machine features:

◇ Second RO film automatic, manual operation/flushing, optional touch screen control, man-machine interface;

◇ Secondary RO membrane in the machine can be manual chemical cleaning;

◇ Purified water automatic stop at high water level, automatic start at low water level;

◇ Multistage high pressure pump water shortage protection and overload overpressure protection;

◇ Loss of voltage, undervoltage, overcurrent, short circuit, open circuit, leakage protection;

◇ All stainless steel equipment, automatic operation, no manual integrity.

Medicine, medical apparatus and instruments, biological preparation, electronics, electroplating, electrophoresis, battery, vacuum coating, detergent, cosmetics, glue, chemical industry, pigment, surface treatment, brackish water treatment, etc.

And it can be applied as follows:

◇ Second-stage RO purified water device as the pre-desalination equipment for ultra-pure water production plus EDI becomes an optimal combination of ultra-pure deionized water equipment;

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

◇ Pharmaceutical industry water infusion, injections, tablets, biochemical products, equipment cleaning;

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