Anthracite coal filter materials are commonly used in the water treatment industry. The raw materials are high quality anthracite coal. They are artificially classified, crushed, and screened. The shape is round, smooth outside, rough surface, strong pressure resistance, stable performance, good performance, good in good performance, good performance, good in good performance, good performance, good performance. The adsorption ability can remove harmful substances in water. No need to rinse repeatedly, because of its light quality, it can save power and water resources.
Zhengzhou Jiasheng Water Purification Material Co., Ltd. anthracite coal manufacturer has high carbon content, high density, high strength, good external sight, stable chemical performance, stable chemical performance, and stable, and it can well remove suspended particles. Anthracite coal filter materials are suitable for industrial water and drinking water.
Anthracite coal filter materials, high quality anthracite coal filter materials, water treatment of anthracite coal filter material, two -layer filter tanks with anthracite coal filter material, and three layer filters for anthracite filter material.
The smaller the anthracite coal filter material particles, the better the filtering effect, but the speed is slow and it is easy to run. Therefore, the mesh of the filter is smaller than the particle size of the filter material. In addition, when choosing the granularity of the anthracite coal filter material, you must choose the grades of filter materials in the filter tank or filter tank. For example, the 2-4mm quartz sand filter material for the cushion, then the anthracite coal filter material must be selected 1-2mm, so that the mixed layer or running material will not occur when rushing. 1-2mm anthracite coal filter materials are the most commonly used in so many specifications.
The use of anthracite coal filter materials with garnet filter materials and quartz sand filter materials is the most material for double -layer fast filter pools and three layers of filters and filter tanks promoted in my country. It is a way to increase the filtering speed and increase the amount of water output and increase the ability to cut off pollution, reduce the cost of engineering costs and reduce the most effective way to occupy the area. It is widely used in the processing process before and after the production of chemical, metallurgy, thermal power, pharmaceutical, papermaking, printing and dyeing, and food.
Double -layer filter material fully automatic filter filling anthracite filter materials, quartz sand filter materials and magnet mineral filter materials, which form a different density upper and lower layer of filter material. According to the requirements of water quality, the filter material uses different level ratios. The upper layer is light filter material with smaller density and smaller material diameter. The lower layer is filter material with large density and large particle size. Because the density difference between the two filter materials is large, the rate of decrease in the water is also different, the density sinks quickly, and the density is slow.
Its advantages are: After being rushed by anthracite filter materials, the "light and fine" filter materials can still be kept on the layer of "heavy and thick" filter materials, forming the particle size of the filter material from top to bottom. To the large particle size step filter layer, it improves the penetration ability of filtering water. The most D exacerbation of different density and different levels of filter layer at different levels of filter layer. Set the automatic device every 12h (15min) to make the filter material regenerate thoroughly to ensure its filtering performance. The operation of the double -layer filter filter is greatly affected by the water quality of the water. The concrete settlement effect in the sewage treatment process directly affects the water quality before the filtration.
Compared with the single filter layer filter tank, the double -layer filter material has the characteristics of large filtration and strong filter material regeneration capabilities. The single -layer filter tank is based on quartz sand as the filter material. The sewage interception capacity is poor, the particle size ranges from 0.6 to 3.5mm, the upper layer is 0.6 to 1.2mm, the middle layer is 1.2 to 2mm, and the lower layer is 2 to 3.5mm. After a period of reflection, the diameter of the quartz sand is layered according to the diameter of the quartz sand, and the filter layer gradually increases from top to bottom. The walnut shell filter tank mainly exists with the problem of being prone to pollution oil and glue pollution, high filter material price, regeneration difficulty, and poor backwash effect.
Compared with other sewage treatment equipment, the double -layer filter filter has the advantages of structural compactness, simple process, high filter efficiency, and long filter service life. Cost is of great significance, and can be promoted and applied at the oilfield sewage treatment station. In the backwash operation of the double -layer filter filter, due to the loss of water quality due to the loss of filter material, the management needs to be strengthened, and the filter material is added regularly to ensure the normal operation of the double -layer filter filter.
Gravity settlement: When the raw water passes through the filter layer, the filter particles provide a large amount of settlement area. As long as the flow rate is appropriate, the particles will sink to these surfaces.
Mechanical filtering: When the particles are greater than the gap between the filter material, or the gap between the deposited suspended particles, the particles are cut, so that the surface filter pores are smaller and smaller, and the particles are intercepted.
Adsorption condensation: Generally as the surface of the sand particles of the filter material, it has negative charges, which can adsorb particles with positive charge, forming a positive charged film, which can condense the negatively charged colloid on the surface of the sand particles.
Filtering requirements: have enough mechanical strength; have sufficient chemical stability, do not dissolve during filtration, do not produce toxic, harmful substances; there are appropriate grades, uniform shape and pores. Generally, solid particles such as pomegranate sand filter materials, anthracite filter materials, coconut shell activated carbon, coal granular activated carbon, magnet mineral filter material and other solid particles.
Anthracite coal filter materials and quartz sand filter materials are used in my country, which are double -layer fast filters and three -layer filters, filter tank filtration materials promoted in China. It is a way to increase the filtering speed and increase the amount of water output and increase the ability to cut off pollution, reduce the cost of engineering costs and reduce the most effective way to occupy the area. It is widely used in the processing process before and after the production of chemical, metallurgy, thermal power, pharmaceutical, papermaking, printing and dyeing, and food.
