An apparatus introduces partially-purified, softened makeup water into an open recirculating cooling system by injecting proportionated softened makeup water into a secondary side system (such as for filtering the system water) and connected to its primary recirculating system. Proportional unsoftened makeup water is introduced through the secondary side system lines. In particular, the present apparatus and method includes controlling proportional additions (via batch or continuously) of softened and unsoftened makeup water based on cycles of concentration of the system water, and based on characteristics (e.g. conductivity) of the unsoftened makeup water. For example, the present innovation allows the water softener equipment to be placed inside the building where components are easier to install, service, and maintain, while still resulting in optimal control for purposes of minimizing total makeup water required. This results in a more environmentally friendly system with less water usage and installation/maintenance savings.
