Abstract: “Conventional septic tank is the main on-site treatment system used in remote unsewered areas of Kuwait. Reclamation and reuse of septic tank effluents have a potential of being a substantial new source of water. However, the effluents of such conventional septic tanks usually do not satisfy the requirements for reuse. The Kuwait Institute for Scientific Research (KISR) has recently conducted a study that aimed at selecting the best add-on treatment system that can treat septic tank effluents to a level satisfying Kuwait’s national guidelines for reuse in restricted irrigation. This paper reports the performance of one of the studied add-on treatment trains, System 1.”
