Cocopeat is the dust obtained from grounded coconut shells, once the fibers have been removed. It can be incorporated into biofilter for the treatment of wastewater. The performance evaluation of cocopeat prepared from coconut shells in treating sewage wastewater, textile wastewater and dairy wastewater was studied. cocopeat biofilter was constructed using cocopeat, pebble and coco coir and wastewater samples were filtered through biofilter. Parameters like BOD, COD, Ammonia, Nitrate, TSS, Sulphate, phosphorus, chromium, TDS and TS were determined before and after treatment of wastewater samples. Analysis of sewage effluent showed that reduction in BOD, COD, Ammonia, Nitrate, TSS, and Phosphorous was 90% ,85%, 92.86% ,81.82%, 77.78% and 70.10% respectively at 22 days HRT. Similarly, in Textile wastewater BOD, COD, TS, Chromium and TDS were reduced up to 92% ,81%, 64.75, 95% and 62.5% respectively whereas in dairy waste water BOD was reduced upto 95.09 %, COD was reduced upto 94.9%, Oil and grease was reduced upto 75%, TDS was reduced upto 66%, TS was reduced upto 69.9%, TSS was reduced upto 76% and sulphate was reduced upto 53%. During the period of investigation, it was observed that cocopeat filtration system was efficient to treat dairy, textile and sewage wastewater also it occupied less space, had low construction cost and was easy to install.
