Ortho-Wash Troughs: Guaranteed Filter Media Retainage

Did you know that Orthos manufactures media retention troughs for low-freeboard granular media filters? In this Orthos Liquid Systems video chat, Stuart Humphries, Director of Filtration Technologies for Orthos, explains how media loss is prevented during combined air-water backwash using Ortho-Wash™ baffled troughs.  Sustained air-water backwash may be run as long as desired regardless of the distance from the media top to the trough bottom. 

Ortho-Wash™ troughs are constructed of 304- or 316 stainless steel to provide long, clear spans, durability, and maintenance-free service.

Remember Orthos’ HUGE life cycle cost benefits– At the end of the filter’s life cycle (~25 years), in contrast to a complete plastic block or folded sheet metal underdrain overhaul, nozzles are simply replaced
potentially saving $Millions.
