The water will be transferred to Panoche and the solid salt will be further processed by WaterFX and industrial partners into various downstream by-products that can be sold into the industrial and chemicals markets. Examples of these by-product materials are building components (gypsum), metals, selenium, and recovered fertilizers.</i><p>I think if they were distilling seawater they would probably end up discharging brine.
