In recent years, many investigations have been accomplished to improve the efficiency of starchy wastewater treatment systems. In order to achieve stringent discharge standards, several methodologies have been applied that are included from using traditional activated sludge systems to modern membrane technologies. On the other hand, high rate of population growth has created rising rate of consumption, rising rate of pollution generation, and more demands for resources. So, making an assessment on the starchy wastewater treatment processes to select the more efficient one seems to be necessary . Generally, starchy wastewater treatments are divided into three main subsets: (i) biological, (ii) chemical, and (iii) physical methods, and also in some cases a hybrid system has been used . In this work, the methods applied in recent papers and patents for treating starchy wastewater around the world have been reviewed.
