Potential Application of Orange Peel as an Adsorbent for the Polluted Pond Water

Organic filtration is a practice to eliminate the colour, chemical oxygen demand (COD) and some heavy metals. In this thesis, orange peel was taken as natural adsorbent for the reduction of COD is river water, nearest to the soap factory. An orange peel, carbon powder, fine and coarse aggregate were taken as a filter media. An influent was allowed to pass through the filter media with a contact period of 45 days. Aggregate were used to remove the suspended particles and carbon powder was used to remove contaminates and impurities using chemical adsorption. An orange peel could be removed the colour and COD in the waste water. The physical and chemical characterisation were analysed for influent effluent. An effluent has achieved in the reduction of COD and other parameter like pH, total solids, turbidity etc. It could be compared with IS standards for waste water. Finally concluded, the effluent can be used for non- portable domestically uses, and also for cooling and washing purposes in industries.
