Activated carbon drinking water purification

Activated carbon is a specially treated carbonaceous material. It is made of coconut shell, fruit shell and coal as the main raw materials through carbonization and activation processes. It has a black granular appearance, a developed pore structure and a large specific surface area, so it has extremely strong adsorption performance.

 

1. The concept of Activated carbon

Activated carbon is a specially treated carbonaceous material. It is made of coconut shell, fruit shell and coal as the main raw materials through carbonization and activation processes. It has a black granular appearance, a developed pore structure and a large specific surface area, so it has extremely strong adsorption performance.

The U.S. Environmental Protection Agency (EPA) considers adsorption by activated carbon to be the best available technology for the removal of many contaminants in surface water. Activated carbon aids in the removal of：

• Compounds that cause unwanted taste, odor or color
• Organic materials from decaying plants and other naturally-occurring contaminants
• Disinfection byproducts (DBPs) linked to chlorine and alternative disinfectants
• Algal toxins and cyanotoxins, such as microcystin-LR, cylindrospermopsin and anatoxin-A
• Endocrine-disrupting compounds that can adversely affect hormonal systems
• Pharmaceutical and personal care products (PPCPs) contamination
• PFOS/PFOA
• Pesticides
• Heavy metals

Different types of activated carbon have different treatment areas

Granular activated carbon：In the water purifier, the granular activated carbon filter can integrate adsorption, filtration, interception and catalysis, effectively removing pesticides, pesticide residues, organic solvents and other chemical pollution caused by industry, and can also remove organic matter, residual chlorine and other radioactive substances in the water, and has the effect of decolorization and deodorization.

The water purification series activated carbon is primarily crafted from coconut shells, undergoing rigorous refinement and processing with cutting-edge production techniques. Boasting a well-developed pore structure, high strength, minimal impurity content, suitable particle size, low resistance, and ease of regeneration, this product excels in water purification. It efficiently eliminates odors and enhances water purity, while demonstrating a high removal rate for various impurities, including chlorine, phenol, arsenic, lead, cyanide, pesticides, and other harmful substances. It finds extensive application in various large, medium, and small water purifiers, serving as a key component for filling, dechlorination, oil reduction, and purification in urban drinking water, purified water, distilled water, ultrapure water production equipment, and for the deep purification treatment of various industrial wastewaters.

3. The principle of activated carbon to purify drinking water

The principle of activated carbon to purify drinking water is mainly based on its strong adsorption performance. Its surface has a large number of tiny pore structures, which can adsorb harmful substances such as organic matter, residual chlorine, pigments, odors, and heavy metal ions dissolved in water. When water flows through the granular activated carbon layer, these harmful substances will be adsorbed on the surface of the activated carbon, thereby achieving the purpose of purifying water quality.

4. Activated carbon drinking water purification equipment

In drinking water purification, activated carbon is usually filled in a filter or filter element to form an activated carbon water purifier or activated carbon filter element. These devices effectively remove harmful substances in water and improve water quality through physical filtration and activated carbon adsorption. For example, an activated carbon water purifier is a device that uses activated carbon as the main filtering material, is installed on a tap water pipe, filters municipal tap water, and obtains healthy and safe drinking water.

5. The main impurities removed by activated carbon when purifying drinking water

Organic matter: including natural organic matter and artificially synthesized organic matter, such as pesticides, detergents, dyes, etc.

Residual chlorine: Water plants usually add chlorine for disinfection, but residual chlorine is harmful to the human body. Activated carbon can effectively remove residual chlorine in water.

Pigments and odors: Pigments and odors in water usually come from microorganisms, organic matter and inorganic matter in the water. Activated carbon can remove these pigments and odors through adsorption.

Heavy metal ions: Such as lead, mercury, chromium, etc. These heavy metal ions pose a potential threat to human health. Activated carbon can effectively remove heavy metal ions in water through its strong adsorption capacity.

In short, activated carbon, as an efficient and environmentally friendly adsorption material, has broad application prospects in the field of drinking water purification. By using activated carbon and its related equipment reasonably, harmful substances in water can be effectively removed, water quality can be improved, and people's drinking water safety can be guaranteed.
