1、 Equipment name: fully automatic reverse osmosis pure water equipment with softening

gd55光大彩票2、 Specification and model: hdnro-4000

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product function description:

gd55光大彩票1. Mechanical filter:

gd55光大彩票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.

gd55光大彩票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:

gd55光大彩票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. Security filter:

After pretreatment, a safety filter is arranged in front of the high-pressure pump to prevent the impurity particles larger than 1um from entering the high-pressure pump and damaging the high-pressure pump and reverse osmosis membrane. The PP filter element (with framework and good strength) is loose outside and tight inside, and 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.

gd55光大彩票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.

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
