(Summary description)Since the quartz sand of the three-layer filter bed is smaller than the quartz grit of the double-layer filter, and there is a layer of finer heavy anthracite filter under the quartz sand layer, the other conditions are the same, even the filter speed is high. In some cases, the water quality of the filtered water of the three-layer filter media is better than that of the double-layer filter. When using quartz sand, try to use it together. Most of the sewage treatment plants in China implement the Class I B standard in the Pollutant Discharge Standards for Urban Sewage Treatment Plants, and the implementation of the Class A standard can greatly reduce the “phosphorus and nitrogen removal” of sewage. Subsequent to the pollution of the receiving water body, the effluent can be used as water reuse to solve the problem of water shortage in some areas of China. Quartz sand filter

The tail water of the sewage plant enters the bottom of the filter through the inlet pipe, and evenly distributes the water through the water distributor, and then passes through the filter layer from top to bottom. During this process, the tail water is filtered to remove contaminants from the water. At the same time, the content of pollutants in the quartz sand filter material increases, and the degree of pollutants in the lower filter layer is higher than that of the upper filter. At this point, open the air lift pump in the center of the filter and lift the lower quartz sand filter to the sand washer at the top of the filter for cleaning. After the filter sand is cleaned, it is returned to the filter bed, and the pollutants generated by the cleaning are discharged. The quartz sand filter material moves from top to bottom under the action of the lift pump, stirring the tail water. The filter material inside the filter can be cleaned in time and has strong anti-contaminant load impact ability. The special internal structure of the quartz sand filter and its own operating characteristics enable coagulation, clarification and filtration to be completed in the same pool.
 
Common problems and solutions for calcium carbonate in plastics
China has become a big country in the production and consumption of plastic products. In 2006, the output of plastic products has exceeded 40 million tons, ranking second in the world, and has maintained a double-digit annual growth rate for more than 20 years. It is foreseeable that with the increase in domestic consumer demand and the increase in the number of exports to the international market as a world-wide manufacturing base, the annual output of China's plastic products will continue to grow rapidly for a long period of time.

Nano calcium carbonate effect and use
Characteristics of nano-active calcium carbonate: Compared with pure calcium carbonate, it has narrow particle size distribution range, reduced water absorption, reduced oil absorption value and good affinity with resin, which is beneficial to improve the tensile, compressive and wear-resisting properties of the product. After mixing, the melting time is shortened, the balance torque is reduced, the dispersion is high, the coloring is easy, and the surface gloss of the product is increased.
