Sample Case Studies
Fortune 100 Headquarters - LEED Gold Building in Houston, Texas
The facilities manager identified the need to improve water conservation in the cooling system to reduce cost, save energy and minimize chemical usage.
Key Success Factors:
- Reduction of scale and biofouling accumulation in the cooling towers and chillers.
- At least 50% conservation of blow-down water.
- Chemical reduction and optimization.
- Increased lifecycle of equipment, fill material and piping.
- Reduction in energy and maintenance costs.
- 85% blow-down water reduction, which greatly exceeded the 50% goal.
- 75% chemical reduction.
- 50% reduction in maintenance frequency.
- 10% reduction in energy consumption by the cooling towers and chillers.
Chemical Plant in Washington
Due to excessive scale accumulation, the plant's diesel steam boilers were on the verge of being decommissioned for a week in order to be acid cleaned; a process that typically costs over $15,000. In addition, there was a strong possibility the steam boilers required replacement ($350,000 each). The head of maintenance decided to evaluate HydroFLOW’s ability to clean the steam boilers and possibly avoid acid cleaning.
- Within a few days, soft chunks of grayish/reddish scale and “putty” began washing out via blow-down.
- The water softener was bypassed less than a month after installation, which led to an acceleration in the removal of scale from the system.
- Within 2.5 months, the stack temperature of each steam boiler reduced from approximately 650 to 400 degrees F, indicating increased efficiency.
- Within 2.5 months, fuel consumption went down from 400 to 275 gallons per day; which translates to roughly $150,000 savings annually.
- Due to the great results, the customer decided to delay the replacement of the steam boilers ($350,000 each).
