ABSTRACT: This paper
presents the kinetic and functional parametric behavior of cocoyam coagulant
(CYC) in respect of pH and time variation in brewery effluent at room
temperature. The study employed standard nephelometric jar test while CYC
production was based on method reported by Ndabigengesere. Coag-flocculation
parameter such as order of reaction α,
rate constant K, coagulation period, τ1/2 etc. were determined. Maximum parameter values are recorded at K of 6 × 10-1 L/mg·min; dosage of 200 mg/L, pH 8 and τ1/2 of 0.00146 min while the minimum values are recorded at 3 × 10-7 L/mg,
dosage of 100 mg/L, pH
10 and τ1/2 of 20.4 min. The maximum coag-flocculation efficiency E (%)
obtained was 92.28, thus establishing CYC as a potential effective coag-flocculaant.
