Résumé
Agriculture drainage water management faces great challenges in semi-arid regions with significant irrigated agriculture. Drainage management strategies such as cost-efficient treatment and reuse of drainage water for irrigation are needed to control salinity accumulation in irrigation water and soil, to minimize contamination of natural surface water and potential harm to wildlife, and to alleviate local and regional water stress. We propose to develop a low cost solar desalination method to treat agriculture drainage water for irrigation. The technology will be developed based on the Nanophotonic Enhanced Solar Membrane Distillation (NESMD) process invented at Rice University. Building upon several ongoing research activities, the proposed Phase I study will assess the technical and economic feasibility of using the NESMD process for high TDS agriculture drainage water treatment and reuse. Specifically, we will (1) investigate the impact of water quality of agricultural drainage on system performance, (2) investigate the impact of environmental parameters and the mode of operation, (3) evaluate optimal operating conditions, (4) conduct preliminary cost estimation and pilot NESMD system design. The proposed Phase I study will provide the necessary performance and cost data specific to agriculture water applications. It will allow us to identify any remaining technical barriers, and prepare us for field study and demonstration in Phase II

Objectifs
The over archinggoal of the project is to develop a low-cost, efficient desalination system based on the NESMD technology to treat agriculture drainage for irrigation reuse. Through the proposed Phase I research, we expect to achieve the following objectives:1) assessing the commercialization potential of the NESMD technology specifically for agriculture drainage treatment ; 2) completing the bench-scale research and reactor/system design necessary for a pilot study in Phase II.
