3 Things You Need to Know About Traditional Greensand Media

This versatile media is very user friendly but does require periodic maintenance.

  • Traditional Greensand has a differential pressure limit of 8 psi for pressure filter applications. Exceeding this limit may damage your media. (Note: Greensand-plus, the newer generation is less sensitive to differential pressure).
  • The optimal pH range for traditional Greensand is 6.2 to 8.5. Raw water with a pH lower than 6.2 can remove the greensand coating, damaging your media and its efficiency. A simple pH adjustment could prevent your media from needing to be replaced.
  • Regeneration of traditional Greensand every six to twelve months with permanganate is recommended, even if your system is performing optimally. This will ensure the manganese dioxide coating remains intact for contact oxidation. The process of regeneration will recondition the bed, extending the life of your system.

We recommend recharging your media once or twice a year to maintain the performance of your media. Have additional questions about regeneration of your greensand media? Contact us!
