The Dequest Business is offering unique specialty additives to meet the needs of these industries that deal with water management, industrial processes or applications where water plays a crucial role.

More than 40 years ago, Dequest pioneered the development of phosphonate based antiscalants. Dequest phosphonates have been the product of choice for antiscalants / dispersants / corrosion inhibitors / chelants in various applications for many years.

Today Dequest offers a broad range of water management solutions that go far beyond phosphonates and also include a wide range of polymeric antiscalants and dispersantsbiodegradable polymers and tailor made products for specific applications. For pre-treatment and post treatment Italmatch can also provide a complete solution of coagulants and flocculants.

Italmatch offers Dequest® antiscalant solutions and cleaners for reverse osmosis/nanofiltration and Albrivap® antiscalants and antifoams for thermal desalination.

Our scale inhibitors can save you money by:

  • Preventing premature membrane replacement,
  • Reducing the downtime caused by frequent (membrane) cleanings,
  • Improving plant operations via; - stabilizing high recover rates, - reducing energy costs, - reducing water consumption and concentrate production
  • Reducing overall chemical treatment costs (pretreatment, acid, antiscalants and cleaners).
  • Extending equipment (thermal units) life via reducing acid cleaning frequency
  • Maintaining heat exchangers surfaces clean
  • Allowing units (MED and MSF) runs in more severe conditions (higher Top Brine Temperature);

No matter your individual needs, whether municipal or industrial, Italmatch can provide the right solution which will minimize inorganic scaling of your membranes and thermal desalination units.
