Anthracite filter material, as an efficient water purification material, is widely used in water treatment projects. This article will elaborate on the working principle of anthracite filter material and analyze its application in water purification through vivid examples.
Anthracite filter material, also known as activated anthracite, is a highly efficient filter material selected from high-quality anthracite. It has the advantages of large specific surface area, developed pore structure, high mechanical strength, good chemical stability, etc., and can effectively remove suspended matter, colloids, bacteria, viruses and other harmful substances in water.
Anthracite filter media is a granular material processed by a special process, and its main raw material is high-quality anthracite. The following are the appearance and characteristics of anthracite filter media:
Appearance: Anthracite filter media is irregular granular, with a smooth surface and hard texture.
Color: The color of anthracite filter media is black or dark gray.
Particle size: The particle size range of anthracite filter media is 0.5-2mm, which can be adjusted according to actual needs.
Porosity: The anthracite filter media has a high porosity, which is conducive to the filtration of water flow and the removal of sediment.
Chemical stability: Anthracite filter media has high chemical stability and is not easy to react chemically with other substances in water.
Environmental protection: Anthracite filter media is an environmentally friendly material that can be naturally degraded and will not pollute the environment.
Pretreatment: Before filtration, the raw water needs to be pretreated, including the removal of suspended matter, colloids, grease and other impurities.
Filtration: The pre-treated water is introduced into the filter layer with anthracite filter media. The porous structure of the anthracite filter media and the flushing effect of the water flow intercept the impurities such as suspended matter and colloids in the water on the surface of the filter media, thus achieving filtration.
Sedimentation: The filtered water enters the sedimentation tank, and the filter cake formed on the surface of the anthracite filter media creates resistance to the water flow, slowing down the water flow and facilitating the sedimentation of the sediment.
Backwash: When the filter layer is seriously clogged, the anthracite filter media needs to be backwashed to remove impurities on the filter media surface and restore the filtering effect.
Detection and discharge: After the filtered water passes the test, it can be discharged to the subsequent treatment unit or used directly.
Adsorption
The adsorption effect of anthracite filter media refers to its strong adsorption capacity on the surface, which can adsorb harmful substances such as organic matter, odor, and pigments in the water. This is because the anthracite filter media has a rich pore structure, and the pore surface has a certain charge, which can adsorb harmful substances in the water.
Screening effect
The screening effect of anthracite filter media refers to the screening of suspended matter, colloids and other particulate matter in the water by its pore size. When water passes through the anthracite filter layer, larger particulate matter is intercepted on the surface of the filter layer, and smaller particulate matter flows through the filter layer with water, thereby achieving water purification.
Biodegradation effect
The microorganisms in the anthracite filter media can use the organic matter on its surface to grow and reproduce, and remove organic matter in the water through biodegradation. At the same time, microorganisms can also produce biofilms to enhance the filtering effect of the filter material.
Chemical reaction
During the filtering process, the anthracite filter material can react chemically with harmful substances in the water, such as oxidation, reduction, neutralization, etc., thereby removing harmful substances in the water.
Application examples of anthracite filter media in water purification
Urban water supply
In many urban water supply projects in my country, anthracite filter media are widely used in water purification. Through the filtration of anthracite filter media, suspended matter, colloids, bacteria, viruses and other harmful substances in the raw water can be effectively removed to ensure the safety of water supply.
Industrial wastewater treatment
Anthracite filter media also plays an important role in industrial wastewater treatment. Taking a chemical plant as an example, after the wastewater of the plant is filtered through anthracite filter media, the COD removal rate can reach more than 80%, which greatly reduces the pollutant content in the wastewater.
Agricultural irrigation
The application of anthracite filter media in agricultural irrigation can effectively purify water sources, improve irrigation water quality, and promote the growth of crops. In an agricultural irrigation project, anthracite filter media was used for water purification, which greatly reduced the content of suspended matter, colloids and other harmful substances in irrigation water, ensuring the growth needs of crops.
