POREX® Underdrain Plates

Porex Underdrain Plates for Municipal & Industrial Water Treatment, Process Water Treatment, and Drinking Water Treatment.

POREX® Underdrain Plates were developed to support sand and multimedia filtration beds in municipal, industrial, and residential water treatment processes. These plates function like a "false floor" allowing for maximum, uniform water flow-through in either direction without loss of filtering media. This enables automatic backwashing of the filtration system for improved bed regeneration and long system life.

Porex Underdrain Plates offer durability, efficiency, and easy installation to water filter treatment systems. Customized plate tooling and fabrication processes are also available.
