Optimization of RO desalination systems powered by renewable energies. Part I: Wind energy

Operation of an experimental RO plant connected directly to a wind system without energy storage was studied. The data obtained confirm the wide spectrum of operation of the plant with respect to the power available and the operation of the system.

The development of an RO plant for variable charges is presented. The plant has been working for more than 7000 h, generating a history for analysing the behaviour of the plant. The membranes allow a variable functioning without deteriorating, although additional information is needed for the aging study. The results obtained reveal the optimum control for the reduction of the energy consumption in this type of design that consists of obtaining adequate recovery membranes (40–43%). The control system must take the plant to an adequate recovery for each available power, this being possible by use of a simple programme.
