Welcome to the ABC of water treatment

Each week, we spotlight an essential chemical used in water treatment. In this episode, we focus on antiscalants, a group of chemicals that keep your water treatment system operating efficiently. Learn how antiscalants can improve your operations. 

What are antiscalants?

Antiscalants are specialty chemicals used in water treatment to prevent scale deposits on surfaces. Scale, consisting of minerals such as calcium carbonate and magnesium hydroxide, significantly reduces the efficiency and lifespan of water treatment systems.

Read on to learn more about its applications, benefits and other key insights.  

Applications in water treatment 

  • reverse osmosis systems: Prevent scale formation on membranes, maintaining efficiency and extending membrane life
  • boiler water treatment: Avoid scale buildup, ensuring efficient heat transfer and reducing maintenance costs 
  • cooling water treatment: Prevent scale deposits in cooling towers and heat exchangers, improving heat exchange and reducing corrosion risks
  • desalination plants: Crucial in preventing scale formation in thermal and membrane-based desalination processes
