Quality Assessment of Waste Waters Generated by some Important Hospitals from Cluj County

Abstract

Hospitals produce large quantities of waste water that may contain various potentially hazardous materials. Moreover, these effluents usually do not undergo any specific treatment before being discharged into the urban sewage networks. As a consequence, a proper management of the hospitals effluents is vital. In the present study, the quality of the effluents, generated by 11 important hospitals from Cluj County was investigated. The analyzed parameters were: pH, chemical and biochemical oxygen demand, total suspended solids, residual free chlorine, and detergents. For all the effluents, the biochemical oxygen demand and the detergents content were within the permissible limits for waste water discharged in the urban sewerage system, while the other parameters exceeded the permissible limits.
