Powdered activated carbon is typically made from sawdust and coal through processes such as carbonization, activation, and grinding. It is commonly used in static adsorption operations for water deodorization and treatment, as well as in small-scale industrial or municipal sewage treatment.
Granular activated carbon can be categorized into different types based on the raw materials used, such as coconut shell activated carbon, fruit shell activated carbon, and coal activated carbon.
Coconut shell activated carbon is widely regarded as the best type of activated carbon, offering excellent adsorption speed, capacity, and strength. Different types of activated carbon can be selected based on specific water treatment processes.
Decolorization: Activated carbon effectively removes color from water, making it clear and translucent. It is commonly used in drinking water purification, sewage and wastewater decolorization, printing and dyeing wastewater treatment, aquaculture water treatment, and groundwater purification.
Deodorization: Activated carbon can reduce or eliminate various odors. It is primarily used in sewage treatment and wastewater discharge processes.
Absorbing waste: it can effectively remove various impurities in water, such as removing organic matter, reducing COD, removing heavy metals, toxic substances, radioactive elements, etc., such as some chlorides, calcium and magnesium ions, lead, arsenic, detergents, pesticides, and some cyanide. , sulfur, etc.
