Application site of sand filter tank in Guilin, Guangxi





Application site of sand filter tank in Guilin, Guangxi

The sand filter tank is also a pressure filter. It is the pretreatment of pure water preparation. It is an important part of water purification system. It contains many filter materials, such as quartz sand, which has small resistance and large flux. The filter material contained in the filter is used to intercept suspended solids and colloidal sediment impurities in the water.

In the water quality pretreatment system, the activated carbon filter can absorb the residual chlorine which can not be removed in the previous filtration, prevent the reverse osmosis membrane from oxidative degradation, and absorb small molecules and organic pollutants and other pollutants from the previous stage leakage. It has obvious adsorption and removal effect on odor, colloid and pigment, heavy metal ions, and can also reduce COD. The SDI value of RO inflow can be further reduced to ensure SDI < 5 TOC < 2. Oppm.

The adsorption principle of activated carbon is: the equilibrium surface concentration is formed on the surface of the particles, and the impurities of organic matter are absorbed into the activated carbon particles, and the initial adsorption effect is high. However, after a long period of time, the adsorption capacity of activated carbon will be weakened to varying degrees, and the adsorption effect will also be reduced. If the water in the aquarium is turbid and the organic matter content in the water is high, the activated carbon will lose its filtration function soon. Therefore, the activated carbon should be cleaned or replaced regularly. The size of activated carbon particles also affected. Generally, the smaller the activated carbon particles, the larger the filtration area. Therefore, powdered activated carbon has a large total area and good adsorption effect, but it is easy for water to flow into the aquarium, which is difficult to control and rarely used. Granular activated carbon is not easy to flow due to the formation of particles, and impurities such as organic matters in water are not easy to block in the activated carbon filter layer. It has strong adsorption capacity and is easy to carry and replace.

    Application evaluation of chemical wastewater treatment equipment purchased from [Tai'an City]

    The effect of the equipment is very good. I have chemical wastewater here. The local environmental protection department has detected that the pollutant concentration is very high, and they have been worried about the poor treatment. The Fenton + micro electrolysis process designed by the company was half understood and half understood at that time, but after the equipment arrived at the site, the effluent efficiency was improved
