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.
