Abstract: This research work deals with the treatment of domestic wastewater by using novel Borassus flabellifer fiber and Cocos nucifera fiber. Both fibers act as filter media for the treatment process. It has been gradually the removal efficiency of bio-chemical oxygen demand. Scanning Electron Microscopy, Energy X-ray Dispersive, and Fourier Transform Infrared Spectroscopy analysis were done to characterise the novel fiber. The wastewater sample was analysed for BOD, COD, chloride, oil and grease, sulphate, total nitrogen, phosphate, total dissolved solids, and total suspended solids. The sample was treated with natural fibrous materials as fixed aerated beds. The depth of filter media was 15 cm for Borassus flabellifer fiber and Cocos nucifera fiber. When the process is done, the BOD removal percentage of novel Borassus flabellifer fiber is 90.71% and Cocos nucifera fiber is 66.60%. SPSS carried out has a significance of 0.224 (P < 0.5). The mean BOD values of groups 1 and 2 are 84.75 and 304.87, respectively. Similarly, the standard deviation is 0.35410 and 0.78486, respectively. The novel Borassus flabellifer would perform better BOD removal than Cocos nucifera.
