this chapter, as well as relative energy consumption and costs. It should be noted that both energy consumption and treatment costs are highly site-specific; nonetheless, these broad ranges are presented for general guidance and comparative purposes. In selecting potential concentrate minimization technologies, the end user must select based on water quality characteristics, concentrate water recovery goals, disposal options available, permitting requirements, and site-specific characteristics such as available infrastructure, space, and skilled workforce.
