Abstract :
This study was aimed at determining the possibilities of utilizing banana and plantain peels as natural coagulants for aquaculture waste water treatment. Banana and Plantain peels were sourced from Kure Ultra-Modern Market, Minna, Niger State. They were air dried, grinded and coagulants active component extracted using methanol. Jar test were carried out using the two bio coagulants, by addition of 0.1ml, 0.2ml, 0.3ml, 0.4ml, 0.5ml and 0.6ml coagulants doses to aquaculture waste water collected from Alrakees Fish Farm, along Shiroro Road, Minna, Niger State. After the jar test, water samples obtained from the optimum doses, untreated water sample were analyzed for their water quality parameters. SPSS 23 was used for the data analysis of water quality parameters obtained, untreated and treated water samples were compared with control sample using Duncan multiple regression test. The turbidity removal effectiveness investigation carried out on bio coagulants, are and found to be 50% and & 73% for banana and plantain peels respectively. While, on data analysis carried out by Duncan method, it shows that there is statistical significance difference between water quality parameters of control, untreated and treated water samples , with exception of temperature that show no significance difference. Conclusively, banana and plantain peels are effective to be used as natural coagulants in aquaculture waste water treatment. It is recommended that for further studies, both bio coagulants should be blended with inorganic coagulants in order to determine their effectiveness.
