Activated Carbon Filter In Water Treatment Plant
Chlorine can cause damage to membranes and removal of chlorine is therefore essential to protect the reverse osmosis demineralization plant.
Activated carbon filter in water treatment plant. Activated carbon is a charcoal that has been treated with oxygen to open up millions of tiny pores between the carbon atoms. Municipal drinking water treatment point of use pou and point of entry poe filters industrial process water e g. Often called pressure carbon filter pcf these filtration systems assure optimal carbon utilization widely used in laboratory commercial and industrial water treatment applications where these units play a crucial role in pre treatment for reverse osmosis deionizer and softener plants. Activated carbon is initially treated with oxygen.
Activated carbon filter process basically absorbs unwanted contaminants from waste water. Applications for activated carbon in water purification include the following. Organic materials from decaying plants and other naturally occurring matter which serve as the precursors for dbps. Breweries food power plants chemicals production groundwater and soil remediation industrial wastewater municipal.
Activated carbon can be utilized in a granular gac form placed in filter bed or media through which water passes or can be utilized in a powdered form pac that is fed into the treatment train and removed along with other solids present in the water being treated. The activated carbon has a massive surface area 2000 3000 square metres per gram. Granular activated carbon gac is commonly used for removing organic constituents and residual disinfectants in water supplies. 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.
Carbon several activated carbon filters are connected in series be cause then a maximum load in the first filter can be achieved. Activated carbon filter is used to adsorb chlorine organics tri halo methane thm taste odour and colour from water wastewater. This helps the charcoal open up millions of tiny pores. The use of granular activated carbon in fixed bed filters also gives the.
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. Impuri ties which cannot be adsorbed in the first filter anymore are adsorbed in the next filters and therefore cannot return to the water cycle. 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.
