ABSTRACT

The physico-chemical properties of wastewater effluent from the plants of Nigerian Breweries Plc. Lagos, Nigeria, have been analyzed. The capacity of removal of manganese, lead, zinc, cadmium and Vanadium ion by activated carbon from coconut shell, saw dust and groundnut shell was carried out, and their comparison was also made. Coconut shell, saw dust and groundnut shell which were wastes collected from Okada market, in Edo State, Nigeria were used as adsorbents for the removal of manganese, lead, zinc, cadmium and Vanadium ion from Brewery wastewater effluent. The results obtained showed that adsorbents made from groundnut shell were most effective for the removal of manganese ion, zinc ion and lead ion; cadmium was most effectively removed by adsorbents made from groundnut shell.
