SUSTAINABLE EFFLUENT DETOXIFICATION OF INDUSTRIAL WASTE WATER BY USING PAPAYA SEEDS

In this study, a natural indigenous coagulant like papaya seed was suggested as a substitute for alum.It is readily available and commonly consumed in most urban and rural communities.The powdered material is obtained from the seed of papaya was used to test coagulant rate and dose.This study mainly focused on the removal of turbidity, total dissolved solids and effect of coagulation on pH of sample etc.The experiments were carried out with coagulant dosage of 0.2, 0.4, 0.6, 0.8, 1.0 and 1.2 g/L in raw water sample.89.14% turbidity removal efficiency was obtained from this study and total dissolved solids removal efficiency of papaya seed obtained from this study was 90.29% at a dosage of 0.6g/L.Papaya seed exhibited high efficiency in removing Total Suspended Solids, Alkalinity, Total Hardness, Dissolved Oxygen etc.The purpose of this work was to evaluate the turbidity removal efficiency of the papaya seeds, extracts as a natural coagulant for synthetic and river water samples.To achieve this objective, several jar tests were executed by applying different bio-coagulant dosages, at three concentration levels of raw water turbidity, according to standardized procedures.
