Abstract
Wastewater from domestic and industries contain contaminants that are harmful for the environment as well as our health. Therefore it should be treated before discharging it out. Activated carbons have the highest degree micro-porosity volume. Activated carbons have the largest surface area. It is important to produce activated carbon from the waste peel by using it in eco-friendly method to decrease the pollution and increase economy. The applications of activated carbon are used to treat the wastewater, drinking water and oil industry. Most of literatures produce activated carbon from different peels and they use the same parameters like pH, contact time, temperature and adsorbent dosage. The results of the activated carbon that produces from the peel can treat and remove the colors from wastewater. Phosphoric acid H3PO4 standard solution is better than zinc chloride ZnCl2 solution for producing activated carbon, but in this study the activated carbon will be taken from orange and lemon peels. Effectiveness of activated carbon made from orange and lemon peel is compared in terms of total suspended solid, total phosphorus, chemical oxygen demand, ammonia and nitrate parameters. The designs of study divided into four main steps, first samples and adsorbent collection, second preparation of adsorbent, third preparation of standard solution and the last one is batch adsorption study. The parameters analyzed in the present study are chemical oxygen demand, total suspended solid, ammonia, nitrate, total phosphorus and fecal Coliform. These parameters are compared between the activated carbon prepared from orange and lemon peel. The experimental and filtration procedure is in college laboratory, but the tests are in the Haya laboratory to check the parameter result. The experimental studies revealed that the best results comparing with SP3 parameter is when doing filtration by using orange peel activated carbon because the Fecal Coliform is <10 cfu/100 ml, total phosphorus is 3 mg/L. With this result it can be confidently concluded that activated carbon from waste orange peels is better than waste lemon peels activated carbon that can be used successfully wastewater treatment of SP3 of Haya Water Company.
