CCRO will be utilized to concentrate the Yuma feed water up to at least 16x supersaturation in gypsum, which corresponds to a 95% water recovery. A compact seeded plate-settler with sufficient residence time to allow crystals to form and settle will be used. The suspended crystals in the supernatant of the settler will be separated with a hydrocyclone and recycled to the feed of the settler as crystal seeds accelerating crystal growth. Some of the liquid fraction from the hydrocyclone could be recycled to the feed of CCRO. This will allow to increase water recovery past 95%.
