Walker Station case study
Colloid-a-tron eliminated scale, reduced chemical use, and restored long-term HVAC performance.
Client: Walker Station District Authority
Region: USA
Application: Cooling tower and chiller installation
Sector: Commercial
Product: Colloid-a-tron water conditioner
Walker Station is part of the Fort Bend Independent School District in Texas, operating HVAC cooling systems serving a large public facility.
The challenge
Walker Station faced severe scale formation and corrosion within its HVAC cooling tower and chiller system, despite the use of scale-prevention chemicals
A system assessment showed the damage was extensive enough that full replacement was more economical than repair. Chemical dosing had failed to protect the equipment, increasing maintenance costs and risk to the new installation
The solution
Following a water assessment using the Fluid Dynamics Expert 5 simulator, two 3” Colloid-a-tron units were specified and installed downstream of the circulating pumps as part of the new system installation in February 2013.
Operating cycles of concentration were set in line with the simulator’s recommendations.
Results
Cooling tower and chiller system remained scale-free
No ongoing use of scale-prevention chemicals
Algaecide and biocide consumption reduced by 50%
Lower operating and maintenance costs
Reduced environmental impact
