Description

Gravisand®​ filtration system technology incorporates the principles and advantages of conventional traveling bridge designs but uses improved methods of accomplishing and maintaining filtration and regeneration. Gravisand Systems are a favorite among wastewater treatment plant operators because of their exceptionally low life-cycle costs and their legendary effectiveness in wastewater applications.

Gravisand® filtration systems are ideal for use after suspended growth systems, for tertiary polishing and water reclamation, and algae removal with appropriate configuration.
