gd55光大彩票1、 Equipment name: automatic secondary reverse osmosis purified water system with steam control (with pasteurization)

2、 Specification and model: hdnro-1000

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:

gd55光大彩票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, and 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. Pneumatic control valve:

Pneumatic control valve refers to all kinds of pneumatic components that control the pressure, flow and flow direction of air flow in the pneumatic system and ensure the normal operation of pneumatic actuator or mechanism. The structure of pneumatic control valve can be divided into valve body (including valve seat, valve hole, etc.) and valve core. Pneumatic components and devices can adopt the method of centralized air supply in the air pressure station, and adjust the working pressure of each pressure reducing valve according to the use requirements and different control points. There is a return line for oil tank to collect used hydraulic oil. The pneumatic control valve can directly discharge the compressed air to the atmosphere through the exhaust port.

4. Security filter:

gd55光大彩票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. Secondary 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 flushing device can prolong its service life.

gd55光大彩票6. Pasteurization:

gd55光大彩票Pasteurization is to heat the mixed raw materials to 68~70 ℃, and keep the temperature for 30min, then rapidly cool to 4-5 ℃. Because the lethal point of common bacteria is below 68 ℃ and 30 minutes, the mixture of raw materials can kill pathogenic bacteria and most of non pathogenic bacteria after being treated with this method; the mixture of raw materials will cool suddenly after being heated, and the sharp changes of heat and cold can also promote the death of bacteria.

gd55光大彩票7. UV sterilizer:

UV is a kind of invisible light wave, which exists outside the UV end of the spectrum, so it is called UV. According to different wavelength range, it is divided into three bands: A, B and C. among them, the wavelength of band C is 240-260nm, which is the most effective sterilization band, and the strongest point of the wavelength is 253.7nm. Modern ultraviolet disinfection technology is based on modern epidemic prevention, optics, biology and physical chemistry, using specially designed high-efficiency, high-intensity and long-life C-band ultraviolet light generating device to irradiate water (air or solid surface) with strong ultraviolet C light. When water (air or solid surface) contains various bacteria, viruses, parasites, algae and others After the pathogen is irradiated by UV-C light, the DNA structure in the cells is destroyed, so that the bacteria, viruses and other pathogenic bodies in the water can be killed without using any chemical drugs, so as to achieve the purpose of disinfection and purification.
