摘要

The effectiveness of locally available okra pod powder as natural coagulant under varying pH, dosage and settling time in the removal of turbidity from paint waste water at room temperature has been evaluated. The application of single angle Turbidimeter measurement was employed for the experiment. Such kinetic and functional parameter as coagulation rate constant (K), and coagulation period (τ1/2) , were determined. Statistical parameters such as coefficient of determination (R2), sum of squares due to error (SSE), and the root mean square error (RMSE), were used to evaluate the adequacy of the process. The highest value of 1.7×10﹣4L/mg.min for K is recorded at pH 4 and 100 mg/L dosage with?τ1/2 of 14.91 min and the least value of K, 3.6×10﹣5L/mg.min is recorded at pH 8 and 300 mg/L doses with τ1/2 of 70.43 min respectively. The efficiency of turbidity removal of more than 80% and 95% was achieved at the end of 3 mins and 30 mins settling time respectively, indicating a system controlled by perikinetic method of coag-flocculation. The results exhibited the potential of pulverized okra pod for removal of suspended particle from paint wastewater.
