Activated carbon filter in water treatment plant.

The following is a review of the fundamental aspects of activated carbon and specifically the use of gac as a filter and adsorbent in potable water treatment. Activated carbon filter process can also be used as a pre treatment in other waste treatment processes. Powdered activated carbon to be dosed in industrial wastewater treatment plants according to the bio pac process. Applications for activated carbon in water purification include the following.

Granular activated carbon gac is commonly employed as an adsorption media in many surface water treatment plants. Granular activated carbon of different qualities for the removal of dissolved organic pollutions. As polluted water or air flows through an activated carbon filter chemicals sorb or stick to the surface and within the pores of the granules. These include ion exchange resins and reverse osmosis process.

It protects other water treatment units such as reverse osmosis membranes and ion exchange resins from possible damage due to oxidation or organic fouling. Chlorine can cause damage to membranes and removal of chlorine is therefore essential to protect the reverse osmosis demineralization plant. Whether free chlorine chloramine or chlorine dioxide is added to the water it can be removed in an activated carbon filter before the water is used for process or drinking water purposes. This not only improves taste and minimizes health hazards.

What is activated carbon treatment. Most plants however also rely on gac to provide effective filtration as turbidity reduction is an essential element in maintaining desired water quality. Activated carbon is a material used to filter harmful chemicals from polluted air and water. Organic materials from decaying plants and other naturally occurring matter which serve as the precursors for dbps.

Granular activated carbon management at a water treatment plant ii abstract abstract the rietvlei water treatment plant was extended with a granular activated carbon gac filtration system after an exhaustive series of tests which were started in 1994. Granular activated carbon gac is commonly used for removing organic constituents and residual disinfectants in water supplies. Activated carbon adsorption is regarded as one of the best and most common treatment methods for removing impurities from drinking water both at municipal treatment works and in home filter systems.
