Assessment of Industrial Influent and Effluent Water Quality at a Bottling Company in Aba, Abia State, Nigeria

ABSTRACT

This study assessed water sources (treated water, pond water and harvested rain water) and effluents discharge from a bottling company, Aba, Abia State. A single factor experiment in randomized complete block designs with three replications was used to assess the physicochemical properties of water at various sources. The result shows that pond water and rain water gave significantly the highest and least N and P contents respectively (N: 33.60-5.60 mg/L; P: 12.40-10.30 mg/L). The K contents of the various water point sources were significantly higher as follows: Pond water > Effluent water > Rain water > Treated water (6.50 > 0.30 > 0.20 > 0.20). Pond water was statistically highest in Mg contents when compared to other sources. The Fe contents were significantly higher as follows: Effluent water > Rain water > Treated water > Pond water, while Fe content in pond water wasn’t significantly higher when compared to its content in Rain water. Pond water and treated water were significantly the highest and least (P<0.05) in organic matter (OM) and Organic Carbon (OC) contents respectively. No significant differences existed between color intensity and turbidity values of the various water point sources. Effluent water from the industry and pond water were significantly the least in DO values respectively. Rain water and pond water were significantly the least in BOD concentrations. Effluent water was significantly the highest in TSS values, while the least TSS values were significantly recorded for Treated water and Rain water.
