I'm curious what the mineral content is of the brine water. There are a few cyanobacteria, like spirulina, which thrive in alkaline water that other algae can't handle. One could likely use the run off to process high nitrogen content sewage water and produce spirulina which could be used for food, oil and ethanol production.
