Pollutant removal from cheese processing effluent using effective indigenous natural scavengers.

The goal of this study was to come up with an efficient method for treating cheese production wastewater. Because the effluent has a higher concentration of organic and inorganic materials, the indigenous microbial treatment process was used to effectively remove total dissolved solids (TDS), chemical oxygen demand (COD), and color without the addition of any nutrients. The indigenous microorganisms were tested for color, TDS, and COD elimination by growing them in "nutrient broth medium" loaded with different amounts of cheese effluent. The isolates were identified by 16S rRNA sequencing, and the results revealed that strain 1 was Enterobacter cloacae, strain 2 was Lactococcus garvieae, and strains 3 and 4 were Bacillus cereus and Bacillus mycoides, respectively. After 36 h of incubation, the data were evaluated. Among all the microbes, E. cloacae reduced TDS and COD from the effluent the most (80 ± 0.2% and 87 ± 0.4% COD, respectively). When compared to individual species, consortia were more efficient (86 ± 0.2% TDS and 90 ± 0.3% COD). On treatment, the correlation coefficient "r" for TDS and COD elimination was found to be 1, resulting in a positive linear connection. The current study suggests that microbial therapies are both effective and environmentally beneficial.

Utilization of natural polysaccharide from Tamarindus indica L. seeds for the effective reduction of pollutants in cheese processed wastewater.

The present study was targeted to treat the cheese factory processed wastewater by using natural coagulants. The results were compared with the CPCB wastewater discharge limit and most of the parameters were exceeded the standard limit. In the present investigation, the processed wastewater was subjected to treatment with Tamarindus indica L. plant seed as a coagulating agent. The processed wastewater was treated with Tamarindus indica L. seed powder which is rich in polysaccharides. The proximate analysis confirmed the presence of higher content of carbohydrates, protein, and fiber. Different dosages were used for the treatment. Accurately 0.4 gm was recorded as optimum dosage for the effective removal of pollutants includes 71% of TDS and 75% of COD from the cheese processed wastewater. The GC-MS analysis of raw and treated cheese processed wastewater was carried out and the results showed the degradation of toxic compounds and reduction of pollutants from the processed wastewater. FTIR analysis of T.indica L. seed powder disclosed various chemical group presence and proved higher efficiency in seed treatment.
