Abstract

Natural wastewater treatment systems are constructed for domestic, industrial and agricultural wastewaters in specially design basins filled with graded substrate material and planted with aquatic plants. The treatment processes naturally encountered in natural wetlands are imitated in these systems. Natural treatment systems can be constructed either as surface flow systems or sub-surface flow systems (either horizontal or vertical flow). Each system has special advantages and disadvantages over one another. In Turkey, mostly sub-surface horizontal flow natural treatment systems are preferred. In present study, initially some design criteria for different natural wastewater treatment systems are provided. Then, different systems were compared based on both design criteria, operational and maintenance practices. Finally, a system recommendation was provided for central Anatolia provinces.
