scope:
1.1 This practice covers the calculation and adjustment of calcium, strontium, and barium sulfates for the concentrate stream of a reverse-osmosis system. The calculations are used to determine the need for scale control in the operation and design of reverse-osmosis installations. This practice is applicable for all types of reverse osmosis devices (tubular, spiral wound, and hollow fiber).
1.2 This practice is applicable to both brackish waters and seawaters.
