Cooling Tower Water Use Optimization- EPIC/EPRI

Project Number ET17SCE1020 Organization SCE End-use Process Loads Sector Industrial Project Year(s) 2017 - 2020
Description
The use of physical water treatment technologies for water-cooled cooling towers is growing the U.S. and has been more widely used primarily in the EU where restrictions on chemical discharge and environmental policies encouraging lower chemical usage are wide spread. Physical Water Treatment technologies if properly applied can offer advantages in controlling the primary water metrics of scale, corrosion, fouling and bacteria when applied properly for water, energy and chemical usage savings in cooling towers.
Project Results
Physical Water Treatment technologies if properly applied can offer advantages in controlling the primary water metrics of scale, corrosion, fouling and bacteria when applied properly for water, energy and chemical usage savings in cooling towers. The M&V results confirmed substantial water savings and chemical reduction at both host sites: 30% for the hotel site, with typical practices (COC was increased from 2.3 to 5.9) and 15% for the pharmaceutical site with best practices (COC was increased from 3.6 to 7.8). Chemical usage cost reductions ranged from greater than 30% at the hotel site to ~45% at the pharmaceutical site.
