Comparison of biological and algal treatment of acidic wastewater of steel industry
Author(s): Sharad Khawal, Sanjay Verma
Abstract: Steel industries have a common process of finishing metals to improve and strengthen steel, known as pickling process. The nature of effluent discharged by this process is ultra acidic and it also contains heavy metals and toxic gases. If this effluent is not treated properly and adequately, it can cause severe damage to flora and fauna and to other water bodies like ponds, river, lakes etc. This effluent cannot be successfully and economically treated using conventional physico-chemical methods. Two distinct secondary treatment methods viz.; biological using different biomass and algal treatment are found to be the best alternative methods for treating the steel industry effluent. In present paper, both methods are compared in terms of effectiveness and economy through comparison of experimental data. Algal treatment method was found more suitable to treat such effluent.
