Influence of pH variation on Coag-flocculation kinetics of chitin derived coag-flocculant (CDC) in brewery effluent (BRE)

Influence of pH variation on Coag-flocculation kinetics of chitin derived coag-flocculant (CDC)... Chitin Derived Coag-flocculant (CDC), is a cheap, abundant and eco-friendly deacetylated cationic polymer applied in this study at a pilot scale for the treatment of Brewery Effluent (BRE). The study investigates the influence of varying BRE pH on the coag-flocculation kinetics and behavior of the aggregation process at varying CDC dosages. The best coag-flocculation performance is recorded at rate constant, Km, of 0.0003 l/mg·min, half life, τ1/2, of 0.6846 min, pH of 4, dosage of 100 mg/l and efficiency, E (%) of 99.8791. Minimum efficiency (%) > 96 was achieved at 3 minutes of coag-flocculation, establishing CDC as an effective water treatment agent at the conditions of the experiment. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png World Journal of Engineering Emerald Publishing

Abstract

Chitin Derived Coag-flocculant (CDC), is a cheap, abundant and eco-friendly deacetylated cationic polymer applied in this study at a pilot scale for the treatment of Brewery Effluent (BRE). The study investigates the influence of varying BRE pH on the coag-flocculation kinetics and behavior of the aggregation process at varying CDC dosages. The best coag-flocculation performance is recorded at rate constant, Km, of 0.0003 l/mg·min, half life, τ1/2, of 0.6846 min, pH of 4, dosage of 100 mg/l and efficiency, E (%) of 99.8791. Minimum efficiency (%) > 96 was achieved at 3 minutes of coag-flocculation, establishing CDC as an effective water treatment agent at the conditions of the experiment.
