1、 Equipment name: automatic sand filtration, carbon filtration, softening, fine filtration, UV domestic purified water treatment equipment

2、 Specification and model: hdnscl-5000l

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product function description:

1. At present, the equipment adopts automatic multi-channel valve control backwashing, and the equipment is made of stainless steel. The principle: multi-media deep filtering is adopted, Activated carbon adsorbs a large amount of residual chlorine odor in the source water, removes the total hardness of the source water through sodium ion exchange in the water softener, and filters through 1um precision filter to make the outlet water better than the standard of tap water. Finally, it is sterilized with imported Philips UV sterilizer. The effluent can meet the soft water requirements of life and ingredients. Therefore, the whole machine is simple in device, simple in operation, maintenance and automatic control, and safe and sanitary on site.

2. Multi media 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.

3. 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.

4. 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 use the sodium chloride solution with higher concentration to pass through the resin to restore the failed resin to sodium resin.

5. 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) of external loose and internal tight type. 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.

6. UV sterilizer:

① Ultraviolet is a kind of light wave invisible to the naked eye, which exists on the outside of the ultraviolet ray end of the spectrum, so it is called ultraviolet. According to the wavelength range, UV can be divided into four bands: A, B, C (also called disinfection UV) and D (also called vacuum UV). Band a is 320nm-400nm, band B is 275nm-320nm, band C is 200nm-275nm, and vacuum UV is 100nm-200nm. C-band ultraviolet is used for water disinfection. According to the theory of photons, light is a special form of matter motion and a particle flow which is not connected by particles. Each UV photon with a wavelength of 253.7nm has an energy of 4.9ev.

② When ultraviolet rays irradiate microorganisms, energy transfer and accumulation will occur. The accumulation results in the inactivation of microorganisms, so as to achieve the purpose of disinfection. When bacteria and viruses absorb more than 3600 ~ 65000uw / C ㎡, it has strong destructive power to DNA and RNA of bacteria and viruses, which can make bacteria and viruses lose their viability and fecundity, and then destroy bacteria and viruses, so as to achieve the effect of disinfection and sterilization. On the one hand, UV can make nucleic acids mutate, block their replication, block transcription and synthesis of proteins; on the other hand, the production of free radicals can cause photoionization, which leads to cell death. The sterilization principle of UV sterilizer is to use the irradiation intensity of UV lamp, that is, the irradiation intensity of UV sterilizer lamp is inversely proportional to the distance of the illuminated disinfectant. When the irradiation intensity is fixed, the longer the illuminated disinfectant stays, the closer it is to the germicidal lamp, the better the germicidal effect, and vice versa.

7. Automatic backwash control device:

① Flow product features:

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

■ with key disk locking function.

■ LED dynamic color bar display.

■ long term power failure prompt.

■ 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.
