ABSTRACT
This study investigated the coag-flocculation performance of Mucuna
sloanei seed powder (MSSP) in its natural form for the treatment of textile
wastewater at room temperature. A laboratory bench-scale jar test was employed
for the experiments. The optimum
condition was observed at pH 2 and 1.6g/L MSSP dosage. The optimum condition
achieved >84% colour/TSS removal. The kinetic study of MSSP
performance using curve fitting tool of MATLAB 2015b gave coagulation rate
constant, K11,, and coag-flocculation half time, ,.
The goodness of the fit and adequacy of the experimental data to the primary
model was indicated by R2 > 0.91 at optimum condition and very
low values of SSE and RMSE. Hence, the use of MSSP exhibited strong potentials
for the treatment of textile wastewater.
