Activated Carbon Filter For Water Treatment Pdf
Granular activated carbon gac is commonly used for removing organic constituents and residual disinfectants in water supplies.
Activated carbon filter for water treatment pdf. Activated carbon choice firstly it s important to remember that activated carbon can be used in different forms basically as powdered or granular. The activated carbon filter has been performing very well since the past and still going strong in the water treatment industry. Most activated carbons are made from raw materials such as nutshells wood coal and petroleum. Activated carbon is a favored water treatment technique because of its multifunctional nature and the fact that it adds nothing detrimental to the treated water.
Available as a powdered pac or granular gac material toc basics activated carbon basics toc removal testing methods activated carbon performance activated carbon delivery systems cost data. However re activated filters should only be used in waste water treatment applications. So now you know what is activated carbon filter and how activated carbon filter work in removing harmful contaminants in water. Typical surface area for activated carbon is approximately 1 000 square meters per gram m2 gm.
Water is passed through the adsorber containing the activated carbon. Gac granular activated carbon is utilised in drinking water treatment by installing it in a fixed bed adsorber. Granular activated carbon gac particle size. This not only improves taste and minimizes health hazards.
Spent carbon can be re activated. Mobile activated carbon filters. Even contaminated fire water can be treated by us. Granular activated carbon for water wastewater treatment carbtrol corporation september 1992 rev.
Will it be replaced by other better option in the near future. Activated charcoal is used in water gold and gas purification metal extraction medicine sewage treatment filters in compressed air air filters in gas masks and respirators and many other. One advantage to using ac is its low operating cost and virtual fail safe operation once installed. Furthermore desotec has developed a collection of top of the range adsorption products that maximise performance and hence keep costs down to a minimum.
Carbtrol c o r p o r a t i o n introduction carbon has been used as an adsorbent for centuries. It protects other water treatment units such as reverse osmosis membranes and ion exchange resins from possible damage due to oxidation or organic fouling. Simply the activated carbon exerts a magnetic like pull on the specific impurities and attracts and traps them in the pores of its surface area. One disadvantage is that as the chlorine is removed from the topmost layer of the media the ac provides a damp environment ideal for the growth and proliferation of.
Early uses of carbon were reported for water filtration and for sugar solution purification. Larger than 0 1 mm typical range 0 4 to 2 5 mm bulk dry apparent density 0 22 to 0 5 kg l. As the water passes through the activated carbon the carbon acts like a sponge with a large surface area and absorbs the contaminants in the water. To meet all these challenges desotec offers a customised package with immediate availability.
Compounds from air and water. The dissolved impurities.
