Capacity Expansion and Water Quality Improvements at a Co-located Lime Softening and Membrane Facility

This paper will describe the findings of the engineering assessment and resulting recommendations for an optimal expansion plan and operation of a multi-process treatment facility, including NF, RO and lime softening treatment systems. Other co-located lime softening and membrane facilities could take advantage of a similar process and expansion optimization approach and lessons learned, which can benefit both utilities and customers with reduced capital investment.
