Application of Single Angle Turbidimetry on Coag-Flocculation Effect of <i>Detarium microcarpum</i> Seed in Brewery Effluent

Abstract

Coagulation-flocculation is a proven technique for the removal of suspended solids in wastewater, through the application of single angle turbidimetric measurement. Through this measurement, the coag-flocculation kinetics and functional parameters behavior of Detarium microcarpum in brewery effluent with respect to pH, dosage and time were followed at room temperature. Process parameters such as order of reaction α , rate constant (K), coagulation period τ 1/2 etc were determined. Results indicated that reaction order, rate constant, period, pH and dosage recorded optimum values at 2, 1.8 × 10 -2 L/mg.min, 0.152 min, 4 and 100 mg/L, respectively. Maximum efficiency recorded was 96.07% at 30 min. Detarium microcarpum has shown potential as an effective bio-coagulant for the removal of turbidity from brewery effluent.
