Abstract :

Hospital wastewaters include macro and micro pollutants originated from many source that are laboratories, research units, operating rooms, clinics and drug use. Chemicals used for the treatment and sterilization, pharmaceuticals and personal care products (PPCPs), solvents, radionuclides, endocrine disruptors, disinfectants and heavy metals are discharged to the sewage systems through hospitals. This type of micro pollutants to removal from wastewaters advanced wastewater treatment systems are needed that conventional wastewater treatment systems are inadequate. In addition to chemical procedures such as adsorption and ion exchange, advanced oxidation and membrane filtration processes have great promise for the removal of especially PPCPs. In addition to high removal of organic matter, the possibility of applicability to difficult wastes, low sludge production, high quality disinfection of effluent and less working space requirement are among the advantages of membrane processes. In this study as a priority, in hospitals which have a heavy pollution load, groups of macro and micro pollutants in hospital wastewaters with general characteristics of wastewaters consisting of a variety of sources is discussed in detail. Hospital wastewaters and urban wastewaters were compared in terms of these pollutants. Hospital wastewaters especially in terms of micro pollutants are more complex wastewaters than urban wastewaters. For the removal of macro and micro pollutants in hospital wastewaters treatment options and their implications in the literature are also included in this study.
