英文摘要	Installing windmills in dispersed communities with scarce water resources and a limited conventional electricity grid, such as the semi-arid regions of northeast Brazil with a low human development index, visibly improves people's quality of life. The situation becomes even more challenging when the artesian wells, from which windmills draw water, contain brackish water, as more energy must be employed for desalination. Reverse osmosis (RO) desalination systems have been employed worldwide and are todays most common. However, RO membrane systems can only withstand mild pressure variations, which can limit their direct use with conven-tional windmills since windmills' reciprocating pumps produce abrupt pressure variations. In this context, the present work aims to experimentally quantify the pressure gradients caused by piston pumps driven by windmills and confirm whether they can be used in conjunction with RO systems. To this end, an experimental apparatus was constructed, comprising a geared motor with a frequency inverter to simulate the windmill, a piston pump, and a conventional RO system. As a potential solution to mitigate abrupt pressure variations, a hydraulic pressure accumulator was utilized. As anticipated, high-pressure gradients were observed that exceeded the limits supported by the membranes during testing of the reference case (without a pressure accumulator). By employing the pressure accumulator, a reduction of 68.1% in pressure gradients was observed for the tested wind speeds, thereby enabling the direct coupling of windmills to RO systems in low wind speed conditions.
