Abstract

The research aimed at evaluating the potentials of consortium of banana, orange and potato peels as bio-sorbents in the purification of paint industrial wastewater, using column adsorption technique. The experimental conditions observed were pH 4 and 8 and adsorbent doses 1 g and 2 g. Atomic Adsorption Spectrophotometric method was adopted to evaluate the physicochemical properties of the wastewater samples. Results showed that the consortium were effective in the removal of COD, BOD, total solid, colour, turbidity, nitrate, chloride, copper and cadmium while the values of lead, sulphate and phosphate was observed a noticeable increase on the treated wastewater samples. The best experimental conditions according to the adsorption capacity were pH 4 and 1g adsorbent dose. The efficacy of the percentage removal for heavy metal and inorganic anions in the wastewater samples after treatment were in this order: Cl- ˂ Cd˂ NO3– ˂ Cu. It can be deduced that all models can be used reasonably well to describe the behaviour of the adsorption of cadmium, copper, chloride and nitrate. The best model for the column adsorption process was observed to be Yoon – Nelson isotherm model which have the highest correlation coefficient values of the study. The results of this study showed that the agrowastes consortium has the potentials in the treatment of industrial wastewater, which is cost effective, economical and eco-friendly
