Scale and Corrosion Inhibition: HEDP is widely used as a scale and corrosion
inhibitor in cooling water systems, boilers, and heat exchangers. It
effectively prevents the formation of scale deposits and minimizes corrosion on
metal surfaces.

Industrial Cleaning: HEDP is employed in descaling operations to remove scale
deposits from equipment, pipes, and surfaces. It is particularly useful in
removing scales formed by calcium, magnesium, and iron.

Oilfield Operations: HEDP finds applications in the oil and gas industry for
controlling scale deposition and corrosion in drilling fluids, pipelines, and
production equipment.

Reverse Osmosis Systems: HEDP is used in reverse osmosis systems to prevent
scale formation on membranes, ensuring their optimal performance and longevity.

Household and Institutional Cleaning: HEDP is incorporated into household
cleaning products, such as descaling agents and bathroom cleaners, to
effectively remove mineral deposits and stains.

Textile Industry: HEDP is utilized in the textile industry as a chelating agent
to control metal ions and prevent scale formation in various textile processing
operations.

Metalworking: HEDP is employed as a corrosion inhibitor and stabilizer in
metalworking fluids to prevent corrosion and improve the performance of cutting
and cooling fluids.
