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.
