AB  - This study examined industrial effluent treatment, from the treatment plant installed at a brewery in
Benin city, Edo State, Nigeria. Grab samples were gathered from different phases of the treatment process to
determine the efficiency of each phase and its input to the overall performance of the treatment plant. Chemical
and biological analyses were carried out on samples collected daily during peak periods of production and
analyzed within 24 h. Handling and analysis of samples were done according to standard procedures ISO/IEC
17025. The factors investigated include; Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD),
total phosphate, total nitrogen, Total Suspended Solids (TSS), sulphate, total coliform and Escherichia count
<i>(E. coli)</i>. The results showed that the average waste treatment efficiency is about 82% and that the suspended
solids removal is made more effective by the DAF clarifier while the CIRCOX reactor enhances nutrient removal.
Also, the plant has about 59% Coli form removal and 607% <i>E-coli </i>.degradation capacities. These results
authenticate that the anaerobic technology with an aerobic polishing step is effective for treating High Strength
Effluents (HSE) to meet the discharge requirements of effluent into water ways like river accessible to the public.
A system efficiency model proposed in this study would assist in effective plant operation planning.
