California Hospital: 75% Less Biocide, 65% Less Blowdown

Home 9 Case Studies and Results 9 California Hospital: 75% Less Biocide, 65% Less Blowdown
Key results
75% biocide reduction
65% blowdown reduction
<2 year payback period

Case Study from HydroFLOW USA

The Challenges

  • Conductivity kept low to limit fouling
  • High chemical dosing required for control
  • Risk of biofilm and scale formation
  • Cooling efficiency limited by deposits

The Solution

HydroFLOW® Custom units were fitted to condenser return lines and chillers, with side stream and glass bead media filtration, over a 7-month monitoring period. The signal disrupts the conditions that bond scale to surfaces, letting the system run at higher conductivity without fouling.

Key Outcomes

R

Biocide use reduced by 75%, CFU below 1,000

R

Scale chemicals stopped 4 months after install

R

Blowdown water reduced by over 65%

R

Cleanest chiller tubes the team had recorded

Independent Verification

All results in this study were measured and verified by third-party facilities managers and technical staff.
