Abstract
The biological treatment of organic matter and bio-sorption of heavy metals by Genus: Bacillus spp. as bacteria and chlorella vulgaris as algae in sewage water were investigated. Various parameters like Biological oxygen demand (BOD), Chemical oxygen demand (COD), ammonia nitrogen and phosphate were measured after the treatment. Percentage removal rate was found to be 80.49 &83.5% (BOD) and 82.93 & 85.4% (COD) for bacteria and algae, respectively. This is an environmentally safe alternative for treating waste water. The initial time required for maximum bio-sorption and removal of iron ion was estimated to be 48 hrs and 4 days for bacteria and algae, respectively. The bio-sorbent capacity of this biological treatments was investigated. High adsorption to bacteria treated at79 % and algae treated at 87% for iron ion, is achieved in the present study. The value of Freundlich >Temkin equations for bacteria treated and algae, The correlation coefficient (R2) value of bacteria treated at 0.65, whereas for algae treated at 0.97 for iron ion. The order of metal uptake for the dried biomass was found to be Fe removal after 48 hrs 4 days by bacteria and algae treated.
