How does activated carbon work for dechlorination？
The source of chlorine in the water is mainly the remaining chlorine after killing microorganisms in the effluent of waterworks or sewage treatment plants. The residual chlorine in the water will cause harm to the taste of drinking water, human health, and food and beverage quality. Activated carbon can effectively remove chlorine in water. Activated carbon has high removal efficiency, does not produce secondary pollution, and can simultaneously remove the characteristics of organic matter in water, so it is often used in large-scale dechlorination process.
Most of clients will choose fruit shell activated carbon, like coconut shell or apricot shell ctivated carbon for dechlorination. There are many capillary pores in the activated carbon interconnected, so the specific surface area is extremely large. According to the test, 1 gram of activated carbon has a surface area of 500-1000m2, and the activated carbon for filtration is granular, and the particle size is generally 1-4mm. These micropores can play an adsorption role.
The dechlorination of activated carbon is not entirely due to physical adsorption, it also has a catalytic effect, which further converts residual chlorine into carbon. The reaction mechanism is
C12 H2O ==== HC1 HOCI
FAQ about activated carbon for dechlorination
Can coal activated carbon dechlorinate?
Coal-activated carbon can be categorized based on various raw materials, including anthracite, bituminous coal, lignite, and more. Specifically, it's only the activated carbon derived from bituminous coal or lignite that has the ability to effectively remove chlorine.
