Experimental prototype of Reverse Osmosis desalination system powered by intermittent renewable source without electrochemical storage 《Design and characterization for Energy-Water management》

摘要

This work presents the design and the realization of an autonomous small scale brackish water reverse osmosis desalination unit powered by intermittent renewable energy source. Sizing of motor-pumps, desalination membrane, renewable energy source and measuring instruments is detailed and analyzed. Motor-pumps characterization allowed to study their performances for several operating points according to electrical power supplied and to analyze electrical, mechanical and hydraulic power flux. Realization of this experimental test-bench offers the opportunity to develop solutions for electrical power flux control and management in order to increase desalinated water production and enhance desalination unit efficiency.
