Treatment of Wastewater Using Orange Peel Powder as Coagulant

Abstract

In recent days identifying natural and unconventional coagulant supplies for the treatment of wastewater is concentrated very high. In the current experimental investigation, the efficiency of orange peel in the treatment of lake wastewater is carried out. The sample was collected from a lake across the industrial belt in GUEST LINE. Krishna Sagara lake is encircled in a larger zone, and it is a natural lake situated in Anekal taluk, Bangalore. It is also one of the well-retained lakes of Bengaluru and wastewater categorization was made with traditional approaches. Orange peels were added in various dosages (10g, 20g,30g, 40g,50g, & 60g) as coagulants to evaluate the efficiency and dosing intensity. Earlier outcomes using several natural products as coagulants revealed a significant rise in the quality of wastewater with initial and final findings. Current work aims to get the highest effectiveness of selected natural coagulant orange peel powder and proves natural coagulants have a high level of adsorption and elimination of greater concentration of chemical components from wastewater. An investigational study was conducted for the treatment of wastewater from the lake using low-cost adsorbents. In this study, the peels of orange were used as adsorbents and the effect of adsorbent with variant dosages were carried out and evaluated for wastewater. The study shows orange peel was more effective in the removal of pollutants like chlorides 50%, residual chlorine 70%, total hardness 100%, magnesium hardness 100%, and calcium hardness up to 47%. The optimum contact time for orange peel powder of 120min was maintained. The optimum dosage of orange powder is found to 30gm/L.
