17-21 A new membrane softening system is being proposed. The water quality is as shown in the table below. Using RO manufacturer design software (provided by the instructor or obtained from a membrane manufacturer website), develop the process design criteria for the plant. The required water demand is 14,200 m³/d and the finished-water hardness should be between 50 and 75 mg/L as CaCO3.
