In this study the treatment of simulated hexamine wastewater in a lab-scale, subsurface up-ward flow root zone system was investigated.

In this study, the anaerobic digestion of different types of organic wastes including swept flour from the floor of flourmills, leftover food and vegetable waste is investigated. The performance of an anaerobic digester is dependent on the type and composition of the materials to be digested as well as the environmental factors such as pH and temperature.
