| Abstract |
Treatment of leachate is crucial as it is an aqueous effluent generated through
precipitation and degradation of the organic fraction which may infuse into
groundwater which may pollute water sources. This invention presents the
pretreatment of leachate at different dosage using newly plant based Tacca
leontopetaloides coagulant to achieve high turbidity and chemical oxygen
demand (COD) removal. The coagulation was performed using a jar test
experiment at pH 5 and different dosage. The optimum dosage of Tacca
leontopetaloides to achieve highest turbidity and COD removal on leachate
was found at 25 ml/L where the removal were found at 20 and 93%
respectively. The analysis also showed the plant has coagulant properties.
The newly formulated polynession arrowroot, Tacca coagulant can reduce the
chemical coagulant usage due to it abundantly available biomass for leachate
pretreatment.
