WATER RECLAMATION BY PHYSICOCHEMICAL TREATMENT OF WASTEWATER

Abstract

ABSTRACT. Treatment of a high strength acidic industrial chemical waste, which had a COD of about 3000 mg/1 and a pH of 3, was attempted by activated carbon adsorption to evaluate the feasibility of yielding effluents of reusable qualities. The experimental methods which were employed in this investigation included batch and column studies. The former was used to evaluate the rate and equilibrium of carbon adsorption while the latter was used to determine treatment efficiencies and performance characteristics. Parallel operations of fixed‐bed and expanded‐bed adsorbers were contrasted in the column study. Results of this investication indicate that activated carbon was very efficient in removing the COD of the chemical waste. Initial pH adjustments for the wastewater to 7.0 or 11.4 did not increase the COD removal efficiency. Turbidity and nitrogen (total Kjeldahl‐ and ammonia‐N) were removed to some extents by the carbon bed adsorbers while phosphorus (total‐and ortho‐P) was totally unaffected by the carbon treatment.
