1、 Equipment name: full automatic reverse osmosis water supply system with frequency conversion and constant pressure

2、 Specification and model: hdnro-10000l

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product function description:

1. Mechanical filter:

It is mainly used to remove rust, sediment, algae, suspended solids and other impurities in the water, reduce the turbidity of the water, make the turbidity of the water less than 0.5ntu, CODMn less than 1.5mg/l, iron content less than 0.05mg/l, SDI ≤ 5. The control valve can be used for back washing and forward washing at any time to wash off the dirt on its surface, prevent it from blocking and restore its filtering capacity.

2. Activated carbon filter:

Activated carbon has a very strong adsorption and filtration performance, and has a strong adsorption effect on residual chlorine, heterochromatic, peculiar smell, organic matters, etc. in water. As the reverse osmosis membrane is very sensitive to residual chlorine and organics, it is necessary to configure activated carbon to absorb residual chlorine and organics, so that the residual chlorine in the outlet water is ≤ 0.1mg/l, SDI ≤ 4, the first can meet the water supply requirements of the reverse osmosis membrane. Second, it can greatly improve the original taste of the source water. It can be backwashed at any time through multiple control valves or steam operated butterfly valves to wash away the colloid and other pollutants on the surface, prevent the surface of the activated carbon from being surrounded by impurities, prevent it from blocking, and restore its treatment capacity.

3. Softener:

The hardness of water mainly consists of cations: Ca and Mg. When the raw water with hardness passes through the cation resin layer of the softener, the calcium and magnesium ions in the water are absorbed by the resin, and the sodium ions are released at the same time. In this way, the water flowing out of the exchanger is the softened water with hardness ions removed. When the resin adsorbing calcium and magnesium ions reaches a certain degree, the exchange capacity will be lost. At this time, the softener will automatically regenerate the failed resin according to the predetermined procedure, and the failed resin will be restored to sodium resin by using a higher concentration of sodium chloride solution through the resin.

4. Precision security filter:

After pretreatment, the source water passes through the precision filter, the first stage precision filter can intercept more than 5um and the first stage precision filter can intercept more than 1um impurity particles, which makes the effluent water completely superior to the tap water precision. The precision filter adopts the PP filter element (with framework and good strength) which is loose outside and tight inside. The water is filtered from the outside to the inside, which can prolong the time when the filter element is 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.

5. RO unit:

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

6. Variable frequency constant pressure water supply system:

It refers to the water supply mode in which the outlet pressure remains unchanged when the water consumption in the water supply network changes. The outlet pressure value of water supply network is determined according to the needs of users. The traditional constant pressure water supply is realized by water tower, high water level tank, air pressure tank and other facilities.

5. Features:

◇ RO membrane automatic and manual operation / flushing, optional touch screen control, human-computer interface.
◇ RO membrane can be cleaned manually with chemicals in the machine
◇ high water level automatic stop, low water level automatic start

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

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

◇ the equipment is made of stainless steel, fully automatic operation, no need for manual conduct.

Electronics, cosmetics, electroplating, electrophoresis, battery, vacuum coating, detergent, glue, chemical industry, pigment, surface treatment, brackish water treatment, etc. And can be applied as follows:

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

◇ electronic industry water IC, silicon wafer, display tube and other electronic components, PCB washing water

◇ pharmaceutical industry water infusion, injection, tablet, biochemical products, equipment cleaning, etc;

◇ pure water is used for other process water motorcycle parts, home appliance coating, coated glass, cosmetics, fine chemicals, etc.
