1、Equipment Name: Automatic water purification equipment with softening two-stage reverse osmosis (man-machine interface)

2、Specifications and model: HDNRO- Level 2 3000L

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, make the turbidity of 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 rinse 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, softening water device:

The hardness of water is mainly composed of cations: calcium (Ca), magnesium (Mg) ions.When the raw water with 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 element (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 impurities intercepted 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 and high desalination rate. It is easy to maintain and design automatic washing device, which can prolong its service life.Automatic flushing device is designed to prolong its service life.

Five.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.

◇ Purified water high water level automatic shutdown, low water level automatic startup;

◇ Multi-stage high pressure pump water shortage protection and overload and overpressure protection;

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

◇ The equipment is made of stainless steel, automatic operation, without manual integrity.

Pharmaceuticals, medical instruments, biological agents, cosmetics, electronics, electroplating, electrophoresis, battery, vacuum coating, detergent, glue, chemical, pigment, surface treatment, brackish water treatment, etc.And can be applied as follows:

◇ The secondary RO purified water device is used as the primary desalination equipment for ultra-high pure water production.

◇ Electronic industry water integrated circuits, silicon wafers, display tubes and other electronic components, PCB washing water;

◇ Pharmaceutical industry water infusion, injection, tablet, biochemical products, equipment cleaning, etc.

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