Summary:Physico-chemical sewage treatment via coagulation-sedimentation is put in action for suspended solids removal. The effectiveness of this technology concerning the soluble organic content is extremely low. In direct comparison, the use of a biological sand-bed and a high-rate oxidation pond as a tertiary treatment for the chemically treated effluent brought about a substantial increase in efficiency. Experimental investigations performed led to the conclusions that, for the reuse of wastewater for irrigation, chemical treatment is appropriate. For discharge of treated effluents into surface water, combination of the physico-chemical-biological scheme is recommended.
