gd55光大彩票1、 Equipment name: full automatic sand filter, carbon filter, softening fine filter, domestic purified water treatment system

2、 Specification and model: hdnscl-1 ~ 2T

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product function description:

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. Through the control valve, backwashing and forward washing can be carried out at any time to wash off the dirt on its surface, prevent its 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 multi-channel control valve or steam operated butterfly valve to wash away the colloid and other pollutants on its 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. Precision 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. Automatic backwash control device:

① Flow product features:

■ the end face seal is open and close without leakage, and the mechanical performance is reliable.

gd55光大彩票■ with key disk locking function.

■ LED dynamic color bar display.

gd55光大彩票■ long term power failure prompt.

gd55光大彩票■ the make-up water of the salt tank is controlled by the electric ball valve, which can make up water during operation and shorten the regeneration cycle.

■ it can be used in the filtration system. The maximum size of the drainage outlet is the same as that of the water outlet. It can be used in the filtration system after sealing the salt suction outlet.

■ with signal output port, it can be externally connected with booster pump, solenoid valve and other equipment: when the output signal working mode is set as B-01, the instantaneous signal when the valve leaves the operating position is opened; when it reaches the operating position, the instantaneous signal is closed. When the output signal working mode is set to B-02, when the timing / flow of each position reaches the set value, that is, when the motor will start to switch to the next position, the signal will turn on, and when it reaches the next position, the signal will turn off. 　

5. Features:

◇ automatic and manual operation / flushing

◇ softened water regeneration fully automatic

gd55光大彩票◇ high water level automatic shutdown and low water level automatic startup

gd55光大彩票◇ voltage loss, undervoltage, overcurrent, short circuit, open circuit, leakage protection

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