Healthcare - Optimized Cooling Tower Performance

Challenge

The metropolitan hospital was searching for ways to reduce their water footprint while minimizing the risk of legionella growth.

Opportunity

Earthwise's Certified Water Technologists (CWT) surveyed the facility to uncover ways to improve the efficiency of critical equipment, extend asset life, reduce chemical consumption, and provide remote system performance monitoring.

Solution

An Ion-Exchange System and 24-hour monitoring software were installed. The Ion-Exchange System's pretreatment of cooling water allowed the cycles of concentration to increase to 7, resulting in significant savings in utility spend and treatment product consumption. The monitoring software allowed for data driven control. The real-time data gathered within the 24-hour monitoring software improved onsite personnel's reaction to system changes that previously went untreated and decreased system performance.
