1、Equipment name: automatic two-stage reverse osmosis with softening +EDI ultra-pure deionized water system + WFI equipment

2、Specifications and model: HDNRO+EDI-500L

3、Equipment brand: Wenzhou Haidoneng -WZHDN

Four.Product function description:

1, mechanical filter:

It is mainly used to remove impurities such as rust, sediment, algae and suspended matter in water, reduce the turbidity of water, so that the turbidity of effluent is less than 0.5NTU, CODMn is less than 1.5mg/L, iron content is less than 0.05mg/L, SDI≤5.Backwash and forward wash can be carried out at any time through the control valve to wash off the dirt on its surface, prevent its blockage and restore its filtering ability.

2, activated carbon filter:

Activated carbon has a strong adsorption filtration performance, the residual chlorine in the water, heterochromatic, odor, organic matter has a strong adsorption.Because the reverse osmosis membrane is very sensitive to residual chlorine and organic matter, it must be equipped with activated carbon to adsorb residual chlorine and organic matter, so that the residual chlorine in the effluent is less than or equal to 0.1mg/L and SDI is less than or equal to 4. First, it can meet the water supply requirements of the reverse osmosis membrane.The second can greatly improve the original taste of the source water.Can at any time through the multi-way control valve or steam butterfly valve backwash, in order to wash off the surface of the colloid and other pollutants, to prevent the surface of activated carbon is surrounded by impurities can not play adsorption, and to prevent its blocking, restore its processing ability.

3. Water softener:

The hardness of water is mainly composed of cations: calcium (Ca), magnesium (Mg) ions.When the raw water containing hardness passes through the positive resin layer of the water softener, the calcium and magnesium ions in the water are adsorbed by the resin, and the 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, the high pressure pump is equipped with a security filter, which can prevent impurities larger than 1UM from entering the high pressure pump and damaging the high pressure pump and reverse osmosis membrane.The use of loose and tight PP filter (with skeleton, good strength), water from the outside to the inside of the filter, can extend the time of the filter element is blocked.The upper part has an exhaust valve, which can prevent the air from entering the pump and damaging the pump, and the lower part has a sewage valve, which can discharge the trapped impurities at any time.

5. Two-stage reverse osmosis device:

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

6. Terminal filter:

The microporous filter membrane with absolute pore diameter of 0.22um can completely remove the microorganism and its heat source to ensure the asepsis of the water supply and meet the requirements of pharmaceutical water.

7. Ultra pure water equipment (electric desalination 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, 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, power plant boiler supply water, and other applications of ultra-pure water.

8, pH adjustment device:

Because the water produced by reverse osmosis is slightly acidic, the pH value after the secondary reverse osmosis is small, in order to meet the process requirements, and the membrane element requires neutral water intake, which is of great benefit to the long-term stable operation of the secondary reverse osmosis membrane, the desalination rate and the water yield.Therefore, it is necessary to add alkali to the water before the secondary reverse osmosis membrane to adjust the pH to neutral.Adopts German Aldaoxi or American Milton Luo metering pump automatic dosing, accurate measurement, dosing reliable.The dosage is about 2-5ppm.

9. Water for Injection System:

Water for injection (WFI) shall be prepared, stored and distributed to prevent microbial growth and contamination.Materials used in storage tanks and pipeline should be non-toxic and corrosion resistant.The design and installation of pipelines should avoid dead corners and blind pipes.Storage tanks and pipes should be cleaned and sterilized.A non - shedding hydrophobic sterilizing filter shall be installed at the vent of the WFI tank.Water for injection can be stored by above 80℃ insulation, above 70℃ insulation cycle or below 4℃ storage.

V. Features of the machine:

◇ Two-stage RO film automatic and manual operation/washing, optional touch screen control, man-machine interface;

◇ The two-stage RO film can be cleaned manually in the machine.
