Commercial Backwashing Filters

With high efficiency Micro-Z™ filter media.

Outperforms sand & multimedia filters!
Watts® engineered commercial filtration systems for sediment removal incorporate the use of our performance Micro-Z filter media for superior performance. Micro-Z is a granular filter media that outperforms conventional multimedia materials due to its unique Zeolite structure, allowing particulate to penetrate deeply into the filter bed to provide superior filtration at increased flow rates. The increased surface area and deep bed filtration allows Micro-Z to outperform conventional sand filters in every way, including reduced water consumption because the need to backwash is dramatically reduced!

Features & benefits
  • Higher solids loading capability.
  • Designed for higher flow rates.
  • Superior filtration performance.
  • Reduced backwash frequency.
  • Removes finer particulate.
  • Reduced pressure drop.
  • Lightweight for lower shipping costs.
  • Easy to handle.
  • Eliminates need for multimedia
