Abstract
Effluent samples from three food processing industries in Anambra State, Nigeria were monitored for levels of physicochemical properties using standard analytical methods. The results obtained were compared with the Nigeria Federal Ministry of Environment (FMENV) effluent limit to ascertain the level of conformity of these industries with the standard. Results showed that the pH levels of the effluents were acidic in the rainy season and lower than the value set by the FMENV for industrial effluent limit. Hardness levels were higher in the rainy season than values obtained in the dry season and were higher than the set standard (except KP, dry season). Other physicochemical properties of the effluents were either within or below the allowable industrial effluent limit. Two sample paired t-test showed that pH, TS, TDS, TSS and sulphate levels were highly significant (p<0.05) between rainy and dry season. Analysis of variance indicated that there were significant difference (P<0.05) in the mean levels of pH, TS, TDS and nitrate among the three samples but TSS was not significant.
