Abstract

Two pilot projects were dedicated to wind-powered RO desalination. Project #1 had a wind turbine connected to a battery bank, while Project #2 had a wind turbine connected directly to a crank mechanism, a compressor, and a water pump. The target of both projects was to produce potable water from sea water with satisfactory pressure and flow rate of RO permeate. Both projects showed that a combination of RO desalination and wind power is technological feasible when the RO system is operated with fluctuating and intermittent loads following the energy supply characteristic of the wind turbine. Depending on the technical design, the systems provide 1.4 and 7.5 m3/24 h potable water, which satisfy basic needs for small populations in coastal regions.
