ABSTRACT

Treated wastewater has been increasingly used around the world for irrigation, environmental applications, industrial use, groundwater recharge, urban use, indirect potable use and in some rare cases, direct potable use [1,2]. The principal causes preventing the expansion of effluent reuse worldwide are public health and environmental concerns [2]. To reduce the potential risks to acceptable levels, many countries have set regulations or guidelines governing effluent reuse [3,4].
