Activated Carbon Filter For Water Treatment
Granular activated carbon is made of high quality anthracite as raw material refined and processed by advanced technology and the appearance is black amorphous particles.
Activated carbon filter for water treatment. It may then be exposed to other chemicals such as argon and nitrogen and heated again in the presence. Activated carbon is a favored water treatment technique because of its multifunctional nature and the fact that it adds nothing detrimental to the. Activated carbon can be prepared from many common substances that are high in carbon and bituminous coal is a typical starting point. It protects other water treatment units such as reverse osmosis membranes and ion exchange resins from possible damage due to oxidation or organic fouling.
Carbon filtering is commonly used for water purification air filtering and industrial gas processing for example the removal of siloxanes and hydrogen sulfide from. They can remove impurities from large scale community wide water. Granular activated carbon of different qualities for the removal of dissolved organic pollutions. Water purification water purification is a major use of activated carbon.
Activated carbon is used by water treatment facilities to help improve water quality. This not only improves taste and minimizes health hazards. Activated carbon filters are recommended for water without bacteria present. The advantage of using gac for water treatment is that the spent carbon can normally be regenerated via thermal reactivation.
Activated carbon is typically used in filters as it has been treated to have a much higher surface area than non treated carbon. It has developed pore structure good adsorption performance. Activated carbon filters are used in both large and small scale products. Sewage treatment activated carbon used for sewage treatment can effectively deodorize decolorize and effectively remove harmful substances in water quality.
The efficiency of the unit depends on the type of activated carbon installed the filter bed depth the type and concentration of contaminants in the water and the contact time between the water and the carbon filter. First coal is heated in the absence of oxygen. Activated carbon filters are generally employed in the process of removing organic compounds and or extracting free chlorine from water thereby making the water suitable for discharge or use in manufacturing processes. Eliminating organics in potable water such as humic and fulvic acid prevents chlorine in the water from chemically reacting with the acids and forming trihalomethanes a class of known carcinogens.
Powdered activated carbons pac are used in batch treatment processes whereas granular gac grades are generally used in fixed filter beds with the water passing through the filtration medium. Desotec offers different types of activated carbon for wastewater treatment. Many home water treatment devices also employ activated carbon especially to help reduce water odor and taste. Activated carbon filters out impurities that affect taste color and odor without reducing the alcohol content of the drinks.
Granular activated carbon gac is commonly used for removing organic constituents and residual disinfectants in water supplies. One gram of activated carbon has a surface area in excess of 3 000 m 2 32 000 sq ft.
