gd55光大彩票3、 Equipment brand: Wenzhou Haineng wzhdn

gd55光大彩票4、 Product function description:

1. Mineral water equipment technology is a membrane separation process with screening as the separation principle and pressure as the driving force. The filtration accuracy is within the range of 0.005-0.01um, which can effectively remove the particles, colloids, bacteria and macromolecule organics in the water. It can be widely used in the separation, concentration and purification of substances. The ultrafiltration process has no phase transformation, good temperature resistance, acid and alkali resistance and oxidation resistance. The ultrafiltration membrane can adapt to different water quality conditions and separation functions by adopting different formation forms, membrane materials and process design.

2. The mineral water equipment is a kind of solution separation based on the mechanical screening principle and the pressure difference between the two sides of the membrane. The operating pressure is usually 0.2mpa-0.6mpa, and the separation aperture is 1nm-0.1 μ M. it can be widely used in the separation, concentration and purification of substances. There is no phase transformation in the ultrafiltration process, and the operation at room temperature is particularly suitable for the separation of heat sensitive substances, and it has good temperature resistance, acid alkali resistance and oxidation resistance. It can be used continuously for a long time under the condition of 60 ℃ and pH 2-11.

3. 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. 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.

4. Activated carbon filter:

Activated carbon has a strong adsorption and filtration performance, and has a strong adsorption effect on residual chlorine, heterochromate, peculiar smell, organic matter, 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.

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6. Hollow ultrafiltration device:

At present, ultrafiltration technology is a relatively mature technology for mineral water production in the world, and it is also a water treatment technology with wide market application and wide application range. It can precisely filter bacteria, viruses and various floating substances in the water, with low working pressure, large water yield, large water flow, low cost and easy maintenance. The design of automatic flushing device can prolong its service life.

gd55光大彩票7. Ozone sterilizer:

gd55光大彩票Ozone dissolves in water, has the ability of continuous sterilization, long life, good sterilization effect, and its power consumption is small, does not pollute water quality, and has no residue. It is a sterilization method widely used in the production of bottled or barreled purified water. Its concentration is generally 3G / ton of pure water. In the process of using ozone to sterilize, it is necessary to equip the ozone oxidation mixing tower for bundling
