Wastewater treatment in the Mediterranean countries

Abstract

This paper describes a new wastewater treatment concept which was assessed to be technically and economically feasible for Suburban and rural areas in Mediterranean Countries. The treatment consists of a two-step anaerobic high-rate reactor like upflow anaerobic sludge blanket (UASB) reactor followed by vertical flow constructed wetland (CW) and UV radiation. It fulfills the defined criteria, as meeting the standards for water reuse, costs especially for energy are low, sewage sludge production is limited, and operation and maintenance are simple.
