Water Treatment using Chemically Activated Charcoal

Abstract

Water scarcity is a widely experienced problem in several countries in the world like Qatar, Israel, Lebanon and many others. Critical steps have to be taken before this becomes a worldwide phenomenon. The current study focuses on cleaning the greywater, which is about 65% of total wastewater from households, using activated charcoal powder prepared from coconut husk. The material is chemically activated. The shell based activated carbon is used for decolorization of three solution samples: Potassium Permanganate (Purple), Potassium Dichromate (Orange) and Copper Sulphate (Blue) as well as treating the sullage water. Change in normality of above-mentioned samples is calculated before and after treatment by activated charcoal using maximum absorbance data for before treatment as standard. Also, sullage water is treated with activated charcoal and comparison of physical and chemical properties is done before and after the treatment.
