Description
Summary: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 (...), were determined. The highest value of 1.7x10 super( -4) L mg.min for K is recorded at pH 4 and 100 mg/L dosage with ... of 14.91 min and the least value of K, 3.6x10 super( -5) L mg.min is recorded at pH 8 mg/L and 300 mg/L doses with ... 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.
