Membrane Scale Control

Whether you're from a municipal organization that must produce large volumes of clean water, or from an engineering firm that wants to design reverse osmosis systems to operate at higher recoveries, or from an industrial operation, Nalco can provide the right antiscalant that will be cost effective and will prevent mineral scaling of your membranes.

More Information

Nalco's Membrane Solutions team offers PermaTreat antiscalant products for different types of scale. Our scale inhibitors can save you money by:

  • Preventing the need to replace expensive membranes prematurely 
  • Maintaining efficient plant operation at the highest possible recovery 
  • Eliminating or reducing the use of hazardous acids 
  • Reducing water consumption by safely operating at high recovery rates 
  • Using fewer chemicals 
  • Producing less concentrate, and allowing for better environmental acceptance of that concentrate 
  • Reducing energy costs 
  • Reducing the downtime caused by frequent membrane cleanings

And by using the traced version of our antiscalants you receive the added benefit of online monitoring of antiscalant concentration. This means that an alarm can be triggered if the antiscalant concentration falls below set point, and, if you add the control option, you will be able to maintain an exact level of antiscalant at all times, regardless of variations in feed flow rate and dosing pump variability.
