Fruit pit shell activated carbon was used as an adsorbent for dechlorination and iron extraction from drinking water. The adsorber design, allowing increase apparatus efficiency, increase use efficiency of the effective apparatus volume and treatment degree of the adsorbent’s adsorptive capacity in the layer, consistency of performance of the treated flow and apparatus compactness, was developed. The water flow velocity and treatment time influence on the residual chlorine absorbency was studied. Dependence of the chlorine adsorption value on the equilibrium concentration, as well as dependence of the iron adsorption value by the fruit pit shell activated carbon were determined. Adequate adsorption value by the chlorine equal to 0,02 mg/g and by the iron equal to 0,02 mg/g was attained. This method of the drinking water treatment using the activated carbon can be used in the treatment process of natural waters to remove the residual chlorine and formed chlorine compounds, as well as iron. https://www.biotech-asia.org/vol13no4/dechlorination-and-iron-extraction-from-drinking-water-by-fruit-pit-shell-activated-carbon/ Active carbon; apricot shells; dechlorination; adsorption
