Tap water is an essential resource in people's daily lives, and its quality is crucial to our health. As an important place to provide this resource, water plants need to carry out a series of water treatment processes in order to ensure the quality and safety of tap water. As an efficient water treatment technology, granular activated carbon has been widely used in water treatment in water plants. This article will introduce the application of granular activated carbon in water treatment in water plants.

1.Characteristics of granular activated carbon

Granular activated carbon is mainly made from coconut shells, fruit shells, coal and wood, and is processed through a series of production processes. Products are widely used in drinking water, industrial water, brewing, waste gas treatment, decolorization, desiccant, gas purification and other fields.

Granular activated carbon is divided into coconut shell granular activated carbon, coal-based granular activated carbon, fruit shell granular activated carbon, etc., and wood particles according to the production raw materials.

Common granular activated carbon uses high-quality anthracite as raw material and is refined and processed using advanced technology. It appears as black amorphous particles; it has a developed pore structure, good adsorption performance, high mechanical strength, easy repeated regeneration, and low cost; used for Purification of toxic gases, waste gas treatment, purification of industrial and domestic drinking water, solvent recovery, etc

Granular activated carbon is a porous adsorbent with high specific surface area, developed pore structure and good adsorption performance. Due to its excellent physical and chemical stability, granular activated carbon has been widely used in the field of water treatment. It can effectively remove organic matter, chlorine, odor, color and other pollutants in water and improve water quality. By adsorbing and removing various pollutants in the water, it ensures the cleanliness and safety of tap water.

2. Application of granular activated carbon in water treatment in water plants Remove organic matter and disinfection by-products

The water source of waterworks often contains various organic substances. After chlorination disinfection, these organic substances will produce a series of disinfection by-products, such as trihalomethanes, haloacetic acids, etc. These disinfection by-products pose certain hazards to human health. Granular activated carbon can effectively absorb organic matter in water and reduce its concentration, thereby reducing the generation of disinfection by-products. At the same time, granular activated carbon can also absorb residual chlorine in the water, further reducing the generation of chlorine disinfection by-products. Remove odor and color

The water source of tap water plants often contains various odor and color substances, which will affect the sensory effect of tap water. Granular activated carbon has good decolorization and odor removal effects, and can effectively improve the sensory effects of tap water and improve people's water experience.

Remove heavy metal ions

The water source of the water plant may also contain some heavy metal ions, such as lead, mercury, cadmium, etc. These ions have certain hazards to human health. Granular activated carbon also has a good adsorption effect on heavy metal ions, which can effectively remove heavy metal ions in water, reduce its concentration, and reduce the harm to the human body.

biological pretreatment

Granular activated carbon is also commonly used in biological pretreatment processes to improve the biodegradability of water quality through its adsorption effect and provide better conditions for subsequent biological treatment processes. Through the adsorption of granular activated carbon, organic matter and suspended solids in the water can be intercepted, providing a better environment for the growth of microorganisms, thus improving the effect of biological treatment. In tap water treatment, granular activated carbon is often used in filtration systems. When water passes through the granular activated carbon bed, pollutants are adsorbed on the surface of the activated carbon and clean water flows out, thus improving the quality of tap water.

As a water treatment agent, granular activated carbon has the advantages of simple operation and high adsorption efficiency. However, its use requires regular replacement or regeneration to maintain adsorption performance, which is also a cost and operational management challenge.

With the continuous advancement of technology, people have higher and higher requirements for the quality of tap water. The application of granular activated carbon in tap water treatment is expected to see more improvements and innovations to meet growing water quality requirements.

As an important process agent in tap water treatment, granular activated carbon plays an irreplaceable role in ensuring the safety and cleanliness of water quality. Its efficient adsorption capacity makes tap water more transparent, cleaner and odorless after treatment, meeting people's demand for high-quality drinking water.
