Treatment of Synthetic Greywater Using 5% and 10% Garbage Enzyme Solution

Garbage Enzyme is a complex solution produced by the fermentation of fresh kitchen waste (fruit and vegetable peel), sugar (brown sugar, jaggery or molasses) and water. Use of Garbage Enzyme is emerging as an effective method for treating greywater. When the treatment of synthetic greywater was done immediately after filtration of the Garbage Enzyme solution, the effluent standards were met after 27 days. The treatment time reduced to 5 days when it was treated 60 days after filtration of the enzyme solution. The enzyme solution is rich in organic content. The lower concentrations of 5% and 10% Garbage Enzymes were effective to treat synthetic greywater. Results showed that ammonia nitrogen and phosphates could be completely removed by using Garbage Enzyme solution. Further tests are required to study the removal mechanisms.
