Antiscalants and dispersants

Formation of mineral scales is a common problem in industrial processes, desalination as well as sewage and waste water treatment facilities. Antiscalants are substances preventing crystallized mineral salts (scale) from forming in e.g. water pipes, anaerobic digesters and dewatering trains. Our broad range of polymeric antiscalants and dispersants prevent inorganic scale and crystalization and help reduce maintenance time.

The Kemira KemGuard® product family is a versatile series of polymeric antiscalant and dispersant chemistries designed to handle the most vexing scale control challenges.

Applications for antiscalants

  • Once-through and recirculating cooling water systems
  • Boiler water treatment and sludge dispersion
  • Membrane and thermal desalination
  • Municipal wastewater treatment
  • Beet and cane sugar processing
  • Industrial water treatment
  • Detergents and cleaner formulations

Municipal wastewater treatment

Kemira KemGuard® offers proprietary sulphonated copolymer chemistry and specialised formulations for the control of struvite, vivianite, calcite, hydroxylapatite and other common scales in sewage and wastewater treatment plants.

Industrial cooling & heating applications

The Kemira KemGuard® product line includes a comprehensive portfolio of low molecular weight homopolymers, copolymers and terpolymers, covering a wide range of molecular weight, pH, chemistry and functionality, that are effectively used in cooling tower and boiler water treatment formulations. Kemira antiscalant technology also includes specialised formulations based on multicomponent blends to combat scaling, corrosion and fouling problems. The result is improved economy, better energy and water efficiency, longer equipment life and stable system operation.

Membrane and thermal desalination

The KemGuard® range includes high performance polymers, phosphonates and specialised blends to tackle multiple scales found in thermal and membrane desalination systems, whereas the KemEguard® range offers phosphorus-free biodegradable scale and deposit control solution for desalination systems.
