Turbidimetric Perikinetics Behaviour of Afzelia Bella Seed Biomass for Coag-Flocculation Treatment of Brewery Effluent

Matthew Chukwudi Menkiti, Gordian Mbah, Okechukwu Onukwuli


This current article investigates at room temperature the coag–flocculation behavior of Afzelia bella seed biomass in pH varying brewery effluent (BRE) with respect to kinetics and efficiency. The study employed standard bench scale jar test while Afzelia bella coag-flocculant (ABC) production was based on procedure reported by Ghebremichael. Kinetics data generated were confronted with specified models for the evaluation of functional parameters such as reaction order, rate constant, period etc. The major kinetic results recorded are 2, 8.0 x 10-5 l/mg.min, and 2.4921 minutes for reaction order, rate constant and period, respectively. Maximum 96.1348% efficiency was recorded at pH 4, 100 mg/l and 30 minutes. The results establish at pilot scale and conditions of the experiment the effectiveness of ABC in the treatment of brewery waste water.
