Tagged High-Performance Cooling System Scale Inhibitor

CalciTect is a non-phosphorus scale inhibitor developed to help industrial facilities maintain heat transfer efficiency, reduce chemical and energy usage, and preserve system reliability while meeting their environmental goals.

This technology complements ChemTreat’s FlexPro® and FlexCorr™ non- and low-phosphate corrosion inhibitors, providing another opportunity for facilities looking to reduce or eliminate phosphate discharge from their cooling systems.

How Does CalciTect Work?

CalciTect uses a proprietary polymer formulation to replace phosphate-based inhibitors typically used in industrial water systems to treat calcium carbonate and sulfate scale.

The polymer is tagged with a fluorescent monomer attached to its backbone, allowing for on-line measurement and control of scale inhibitor levels, chemical feed automation, and a reduction in laboratory sampling and analysis needs. The tag helps optimize product feed rate, which may reduce treatment costs.

CalciTect’s fluorescent tag tracks polymer demand: as the tag reading drops, the pump increases product feed to maintain the target dosage.

Benefits of CalciTect

This technology offers multiple advantages over industry-standard scale inhibitors:

  • >95% scale inhibition at a low dosage of 2.5, compared to an average of 78% scale inhibition with phosphonate and acrylic/maleic homopolymer treatment under high LSI conditions
  • Improved cost performance based on ratio of dosage to scale inhibition rate
  • Enhanced metal and clay dispersion properties to reduce deposition on cooling and heat exchanger surfaces
  • Stable performance when used in combination with oxidizing biocides
  • Consistent efficacy across a wide range of cooling tower pH and return temperatures
  • Compatibility with commonly used cooling tower materials

CalciTect can also be used as a scale cleaner and applied in pretreatment systems to help manage RO membrane scaling.

CalciTect polymer tag provides better residual control than PTSA for early detection of scaling stress in cooling systems.

CalciTect exhibits a high percentage of clay dispersancy with respect to dosage, indicating its efficacy in reducing the potential of suspended solid and foulant deposition on cooling and heat exchanger surfaces.
