The kinetic studies of the treatment of wastewater from brewery industry using powdered snail shell was carried out. Three kinetic models (Pseudo-first order, pseudo- second order and intraparticle diffusion) models were used to study the kinetics. Results shows that the treatment fit the Pseudo- second order kinetics. Since the r2 values of most of the parameters were ≥ 0.9. The r2 values for pH, temperature, alkalinity, turbidity, electrical conductivity were 0.999, 0.977, 0.989, 0.995, and 0.999 respectively. TS, TSS, TDS, BOD, COD and DO also have r2 values of 0.992, 0.998, 0.992, 0.995, 0.999, and 0.999 respectively. Also NO3-N, Phosphate and Sulphate have values of 0.964, 0.956 and 0.996. However the physicochemical parameters of the untreated and treated wastewater at different time intervals were also carried out and the results presented accordingly. The proximate and mineral composition of the powdered snail shell were also determined. The stability studies of the snail shell were done using different concentrations of CH3COOH and NaOH. It was observed that the powdered snail shell was insoluble in these acidic and alkaline solution.
