Activated carbon is a widely used water treatment material, which can effectively remove a variety of pollutants from water due to its rich pore structure and large specific surface area. Here are some of the main contaminants that water purification activated carbon can remove:
1.Organics:Activated carbon can adsorb a variety of organic matter in water, including pesticides, petrochemicals, dyes, disinfection by-products, etc. These organics can come from industrial wastewater, agricultural discharges, and municipal sewage, among others. Activated carbon removes these organics from the water by physical adsorption.
2.Inorganics:Activated carbon can remove some inorganic substances in water, such as heavy metal ions (such as lead, mercury, cadmium, etc.), fluoride, sulfide and nitrate. The pore size and surface properties of activated carbon make it have a high adsorption capacity and selectivity, which can effectively remove these harmful inorganic substances.
3.Chlorine disinfection by-products:Chlorine disinfection is a commonly used disinfection method in the treatment of tap water, but it will produce some harmful by-products, such as trihalomethanes, haloacetic acids, etc. Activated carbon adsorbs these chlorine by-products and reduces their concentration in water.
4.Odor and color:Activated carbon has good adsorption properties and can remove odor and color in water. These odors and colors can come from industrial wastewater, algae blooms, humus, etc. Through the adsorption effect of activated carbon, the clarity and taste of water can be improved.
It is important to note that activated carbon, while capable of removing the above contaminants, has a limited lifespan and needs to be replaced or regenerated regularly. At the same time, in the process of using activated carbon to treat water, it is also necessary to pay attention to the combination with other water treatment technologies to achieve better treatment results.
