Abstract
- Garbage enzyme is a dark brown, strong sweet sour fermented smell, complex solution, obtained by the fermentation of fruit/vegetable peels, molasses and water, which has got many functions to degrade, modify and speeding up the reactions. This solution is expected to provide a best alternative method to reduce the higher proportions of suspended solids from dairy waste waters. The main aim of this paper is to find out its efficiency as a replacement of conventional biological methods to reduce TSS in dairy waste waters. It was prepared in the laboratory by mixing 1 Kg of jaggery, 3 kg of fruit peels with 10 kg of water, i.e. in the ratio 1:3:10, respectively. The garbage enzyme characteristics were determined, and 10% enzyme was mixed with the synthetic dairy wastewater at different pHs 4.0, 6.5. The values of percentage reduction of TSS were taken until 5 days. After 5 days the reduction % in case of pH 4.0 was found to be 22% and 26% in pH 6.5. Thus the results show that garbage enzyme is effective in reducing TSS. Also further examinations are to be done to find out the optimum dosage of enzyme and also to check its efficiency in reducing BOD, COD, SCOD, TVS.
