Abstract |
The effluent dairy industries are among the most organic-rich food waste. With high values of lactose, proteins, vitamins and minerals, it is a favorable medium for the growth of microorganisms such as fecal coliforms and streptococci. In addition, it has high levels of COD, total nitrogen and total phosphorus that indicates a significant pollution of the ecosystems where it is drained. This study focuses on the treatment of dairy effluent by two different methods. The first is a physicochemical treatment by coagulation, flocculation; using aluminum sulphate and sodium alginate. While the second process is a biological treatment using Pseudomonas fluorescens and Bacillus spp. The results show a decrease of about 30% of chemical oxygen demand, 49% of turbidity, 78% of suspended solids and 20% of the total phosphorus. The second process has shown a significant reduction of all parameters better than the physico-chemical treatment, with fluctuations in efficacy between the strains tested. In conclusion, we have developed biotechnological processes, which are simple, economical and environmentally friendly for treating the discharges of the dairy industry and reduce polluting factors |
