Abstract
This work investigates the influence of pH variation on coag-flocculation kinetics and performance of Chitin Derived Coag-flocculant (CDC) in removal of Suspended and Dissolved Particles (SDP) from Coal washery effluent (CWE) medium. Key parameters such as rate constant K m , half life t1/2,, and pH etc. were investigated. The best coag-flocculation performance is recorded at K m , of 0.007 l/mg.min, t1/2, of 0.0362min, pH of 8, dosage of 100mg/l and efficiency E(%) of 99.933. Minimum efficiency (%) > 94.00 was achieved at 30 minutes of coagflocculation, establishing CDC as an effective water treatment agent at the conditions of the experiment.
