Abstract


Sewage or waste water treatment and its possible recycling is the need of the hour in view of heavy demand on natural water resources. Indiscriminate disposal of sewage deteriorates the quality of available water. The present study focuses on studying the sewage treatment options for possible reuse for gardening purposes in an academic Institute. Three options are considered (i) conventional secondary treatment without recycle (ii) conventional treatment with recycle (iii) only primary treatment. Bench top model of sewage treatment plant is set up and experiments are conducted for the above options. pH, TS, TSS, BOD and COD values are determined in the laboratory to determine the efficiency of the treatment plant. Cow dung and urea are added as seed and nutrient for the bacterial growth in the treatment plant. It is noticed that the sewage requires only primary treatment and a detention time of above 2 hours is sufficient to reduce TSS by 58% to be safely used for gardening.
