gd55光大彩票4、 Product Description:

gd55光大彩票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.

gd55光大彩票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 as the power. 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.

Five. Equipment preparation:

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.

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, 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 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.

gd55光大彩票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:

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.

5. Hollow ultrafiltration device:

At present, ultrafiltration technology is a mature technology for mineral water production in the world. It is also a water treatment technology widely used in the market and with a wide range of application. 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.
