RFP Title

 

Preventing Hard Water Scaling on Heat Exchangers
RFP Description
NineSigma, representing a Global Appliance Manufacturer, invites proposals describing solutions able to prevent and/or detect scale deposits and fouling on metal surfaces heating potable water.
Background

Hard water, or water carrying a high amount of dissolved minerals, is common across the US and many other countries around the world.  This water is prone to cause precipitation fouling and scale deposits on surfaces it comes in contact with.  These deposits can cause major complications across industrial and residential water handling applications.  Due to the temperature dependence of solubility for many of the dissolved minerals in hard water, this problem is exacerbated when water is heated, such as in industrial cooling water, water heaters and boilers.  The precipitated deposits decrease the efficiency of heat transfer, decrease flow, and lead to increased down time and maintenance.

 

NineSigma’s client is seeking novel mechanisms of preventing and detecting hard water scale deposits that are safe for use with potable water applications.  Solutions may be incorporated as integrated within products and/or offered as add-on devices.

 

Key Success Criteria

The successful technology will:

  • Be safe for potable water applications & compliant with appliance safety standards
  • Prevent scale deposits or suppress rate of fouling on heat exchanging fluid passages and associated metal components
  • Maintenance free or predictable lifetime solution

and/or

  • Be able to measure/monitor/alert the accumulation of scale deposits

 

Possible Approaches

Possible approaches might include, but are not limited to:

  • Coatings or surface modifications for metal heat exchanger surfaces
  • Novel heat exchanging materials
  • Non-depleting devices able to remove minerals from water
  • Depleting devices able to remove minerals from water with long service life ( > 2years)
  • Non chemical water treatment
  • Devices or sensors able to measure, detect, or predict scaling and fouling

 

 

"
Approaches not of Interest

The following approaches are not of interest:

  • Solutions not safe for use with potable water
  • Flow velocity optimization
  • Solutions that interrupt product utility

 

Items to be Submitted

The ideal response will address the following:

  • Non-confidential description of proposed technology including:
    • Mechanism of scaling prevention and/or detection
    • Independently generated or peer-reviewed verification data
    • Duration of protection estimated
    • Description of safety provisions
  • Technical maturity of the approach (concept, prototype, ready to commercialize, commercialized)
  • Team description and related experience
  • Etc.
