Alternative formulations for the reuse of treated wastewater in Menemen plain irrigation scheme

In this study, it is intended to investigate the possibility and technical viability of using the effluents of Izmir Wastewater Treatment Plant in Menemen plain irrigation. The research verified the fact that the influent of the plant generally demonstrates typical characteristics of domestic wastewater with the exception of elevated values of electrical conductivity and salinity. These high values are mainly attributed not only to salt water intrusion due to failing pipes and improper pipe connections of the interceptor canal but also to highly-concentrated pre-treated discharges of various industries within the city. It has also been observed that these high values are as well reflected in the plant effluent hindering its use in irrigation. Considering the strong demand for the treatment plant effluent by the farmers and irrigation unions, this study intends to find out possible solutions for high conductivity and salinity. The research involves the formulation of alternative techniques and methodologies such that the quality of treated effluents would satisfy the irrigation water quality criteria currently effective in Turkish legislation.
