Course objectives:

The course is structured in two sections. The first discusses the decentralized wastewater treatment and the second the water reuse. More detailed, treatment processes, design aspects, and practical issues for pond systems, free-water surface constructed wetlands, subsurface and vertical flow constructed wetlands, land treatment, and onsite treatment systems will be discussed. In the second section issues and applications of effluent reuse will be presented with emphasis on agricultural reuse, groundwater recharge, and indirect potable use.
