Wastewater is one of the most critical problems of both middle and low income countries is improper management of vast amount of wastes. The research is to determine the physicochemical characteristics of the wastewaters and also to asses the effect of the Electromagnetic field (EMF) on the physicochemical factors of the waste waters Waste water samples were collected from two industries in Akure Metropolis. The waste water samples were subjected to physicochemical analyses before and after exposure to Electromagnetic field (EMF) at 1150nT, 1310nT, 3000nT, 5000nT. The presence of some bacteria in the waste water collected from different companies showed their occurrence at different hours during the treatment of the wastewater sample with different EMF strength. a. From the two industries, before EMF treatment industry A had the highest pH value (7.74), Temperature (27.00oC), Total Solid (277.00mg/l.), Total Disolved Solids (256.00mg/l.) Industry B had Total hardness (994mg/l), Chemical Oxygen Demand (13.20mg/l), Potassium (13.23g/l), Biochemical Oxygen Demand (9.60mg/l) Zinc (1.24ppm) and Copper (0.07ppm). From the two industries, after EMF treatment pH (6.47), Turbidity (0.29NTU), Biochemical Oxygen Demand (4.60), Chemical Oxygen Demand (5.40). Industry B had Chloride (10.47mg/l), (600 mg/l). Sulphate (8.70mg/l), after exposure to EMF, the values above listed shows physicochemical factors reduced significantly. Therefore from the study, it was observed that EMF treatment has a significant effect on the bacteria load and physicochemical condition of the waste water samples.
