What is anthracite filter media?

The combination of anthracite filter media and quartz sand filter media is a better material for the double-layer rapid filter, three-layer filter and filter tank which are popularized in our country. Anthracite filter media is an effective way to increase filter rate, increase water output per unit area, double sewage interception capacity, reduce project cost and area. Anthracite filter media is widely used in chemical industry, metallurgy, thermoelectricity, pharmaceutical, papermaking, printing and dyeing, food and other pre-and post-production water quality treatment process.

What is the index of Anthracite filter material?

The common specifications of anthracite filter media are:

0.5-0.8mm，0.8-1.2mm，0.8-1.8mm，1.2-2mm，1-2mm，2-4mm，4-6mm

The effect of anthracite filter media in the filtration process directly affects the quality of filtered water, so the selection of filter media must meet the following requirements: 1, high mechanical strength, the sum of breakage and wear rates shall not be greater than 3% by weight. The chemical property is stable and non-toxic. It is insoluble in ordinary acidic, alkaline and neutral water. The product was determined by China water treatment filter material supervision and testing center: hydrochloric acid soluble rate is 0.68% (ministry standard is 3.5) in all kinds of water sources can achieve good purification effect. 3. The particle size is reasonable and the specific surface area is large. The appearance of the product is spherical and angular, good gloss, by mechanical vibration screening three times, gradation in line with the relevant technical indicators. The uniformity coefficient (K60) is not greater than 1.5(Japanese standard) , the nonuniformity coefficient (K80) is between 1.6 and 2.0, and the voidage is greater than 50% . 4. The range of particle size less than the specified lower limit is not more than 5% by weight, and the range of particle size greater than the specified upper limit is not more than 5% by weight.

Anthracite filter media is a kind of filter media used in water treatment industry. It is a kind of double-layer, three-layer fast filter media. Jiasheng water purification material anthracite filter material is the most important one of the three layers of filter material, because it is directly facing the sewage and is the first layer of filter material for filtering sewage, if the thickness of Zhengzhou Jiasheng anthracite filter media can not be accurately controlled, it will cause unnecessary losses. The following is our summary of the use of anthracite filter media, determine its thickness of several methods:

The amount of sewage and the thickness of anthracite filter media has the most direct relationship, in general, the greater the amount of sewage, filter media layer thickness to slightly increase, if the amount of sewage is small, to reduce the thickness of anthracite filter media.                                                                                                                             

If it is a filter tank, the thickness must be determined according to the size of the filter tank, the size of the filter tank and the thickness of anthracite filter material also has an important relationship, the general thickness of the filter tank is 70 cm, the highest is 85 cm and the lowest is 65 cm.

Using the measured data to determine the thickness, the turbidity of sewage can be measured in advance, and then according to the turbidity to change the thickness of anthracite filter media. Used for filtering and purifying raw and industrial water supply.

The application parameters are determined according to the form of the filter. The general thickness of the two-layer filter media is 280-420 mm, the normal filtration rate is 10-14 m/h, the forced filtration rate is 14-18 m/h, the thickness of the three-layer filter media is 450 mm, the normal filtration rate is 18-20m/h, the forced filtration rate is 20-25m/h. The filter backwash adopts water washing, water vapor washing or auxiliary surface washing. Jiasheng anthracite filter media is often used in various media filter, carbon steel media filter, three-layer rapid filtration system filter.

What is anthracite filter media used for?

Use of anthracite filter media: 

1. The use of anthracite filter media is based on the design of sewage treatment design units, the filter tank or filter equipment will be transported to the various industries of the site 

2. Common anthracite filter media is mainly used in steel plants, Sewage Treatment and Industrial wastewater treatment plants, but also widely used in chemical industry, metallurgy, thermal power, pharmaceutical, paper, printing and dyeing, etc. . 

3.The combination of anthracite filter material and quartz sand is also the best material for double-layer rapid filter, three-layer filter and filter tank. 

4. In the wastewater treatment industry, it is also the most effective way to increase the filtration rate, increase the output per unit area, double the interception capacity, reduce the project cost and reduce the area occupied, the double-layer filter used for sewage treatment and purification will adopt the common anthracite as the theme filtering material. 

Anthracite filter material is the best filter material widely used at present. It has a wide range of applications. The utility model can be used for domestic drinking water, industrial production water and common fast filter of various pond types. Double-layer and triple-layer filters, all kinds of sewage filters, water purification Mechanical filter and pre-and post-production water quality treatment of chemical, metallurgical, thermoelectric, pharmaceutical, papermaking, printing and dyeing, food, etc. .
