This paper describes multiple blending schemes employed by the Town of Jupiter water system since the introduction of enhanced lime softening in the late 1980’s to brackish water reverse osmosis in 1989, addition of anion exchange in 1999 through the process currently being implemented of replacing lime softening with nanofiltration and blending with brackish water reverse osmosis. This paper will present the reasons or basis for choosing each of the processes, qualities of the individual and blended waters, and the plant modifications needed to implement the blending processes. Membranes have played a pivotal role in each of these blends of water and those roles will be presented in this paper.
