Sure, they all sell them, but not as a way to save water. They are sold as a way to increase production and thats it. I am working on two large 7.5 and 6 million gallon per day multiple membrane systems as we speak bu they run 15% recovery just like every manufacturer recommemds. Thats more like 6:1 waste and its actually what Dow, GE and Applied recommend.
