An Innovative Membrane Based Zero Discharge System for Management of Agricultural Drainage water (ADW) and Salt Recovery

Abstract
Implementing a successful zero discharge system is constrained by numerous technological challenges and economic constrains necessitating development of innovative cost-effective solutions and interventions. This paper introduces an innovative integration of separation technologies using high pressure membrane scheme and electrically assisted adsorption separation units. The agricultural drainage water” ADW” could be treated as well as avail high-quality water and commercial salts using this innovative scheme. Three innovative features have been incorporated within the general arrangement of this innovative zero liquid discharge system. The first intervention is related to the introduced electrically assisted adsorption/ion exchange units for eliminating heavy metal species typically present in ADW. Second, improvement represents a sound solution for improving the quality of the brine generated by RO stage to suit the requirements of the second high pressure RO module. Problems of scaling will be greatly minimized by interposing these adsorption/ion exchange units between the two stage RO units. Dealing with the generated brine from the second membrane unit with a remarkable solar assisted engineered artificial wet-land maintains production of commercial salts with minimal adverse environmental impact. The estimated cost is $0.242/m3 of produced water. Keywords - Adsorption, Electro Assisted, Reverse Osmosis Membrane, Wastewater, ZLD.
