Abstract:This paper describes an innovative technology to pre-treat feed water for desalination. An inline coagulation-flocculation-separation (CFS) system is detailed that does not require filtration or sedimentation. Advantages include: scalability, modularity, rapid processing, low energy, and low maintenance. In comparison with conventional and membrane pre-treatments, this technology may allow reductions in capital cost by 30-70%, operations and maintenance cost by 30-40% and land use by 58-77%.
