Salt-water solar-desalination by an innovative HDH

Lake of freshwater forced vulnerable communities to desalination. Also,high energy costs and brines are devastating issues for this approach. Solarhumidification dehumidification (SHDH) systems are low energy and economicalresponse to that problem. In this article with the aim of saltwater solar-desalination,an innovative SHDH design introduced, and in full-scale tested, successfully. In400 m2 full-scale application, 600 m3 saline-water, TDS = 141 g l-1, and 196.2 kWelectrical energy, inputted and 266 m3 freshwater, TDS = 210 mg l-1 with waterrecovery percentage of 44%, resulted. The slat removal efficiency was near 100%,also, surface-time efficiency varied, between 8 to 30 l m-2day-1. In conclusion, itshould be stated, this SHDH would use to produce freshwater of brines.
