Abstract

Wastewater from healthcare facilities poses a major threat to the environment. It is important to protect water resources from the polluted water that is generated from the hospitals. There are many technologies for hospital wastewater treatment, however, because of the stricter regulations for the treated water quality and the availability of modern materials on the market, new technologies for wastewater treatment are constantly developed. Some of these new technologies are using the membrane for separating the active sludge from the treated water and are known as membrane separation processes. In this paper modeling of the permeability characteristics of a silicon carbide membrane (SiC) submerged in membrane bioreactor (MBR) and optimization of the operating parameters using the 3D response surface method, were done. For this purpose, Statgraphics Centurion software was used where the permeability characteristics of the membrane are optimized. The temperature, transmembrane pressure (TMP) and chemical oxygen demand (COD) of the effluent are the input parameters that are used for defining the optimal membrane permeability characteristics. Changing the values of the studied operating parameters, optimal response surfaces of the membrane permeability are obtained. From the results it can be seen that the decreasing of the temperature and decreasing of the COD, positively effects the permeability characteristics of the applied ceramic membrane.
