Ortho-Wash™ Media Retention Troughs

Ortho-Wash™ Troughs

Poseidon Filtration Systems® Ortho-Wash™ process combines air scour and backwash to vigorously clean filtration media while lowering backwash rates and waste volumes.  Ortho-Wash™ baffles, integrally-mounted as part of the backwash trough, prevent media loss by deflecting air and providing an adjacent quiescent volume to settle out lightweight anthracite or GAC.  Negligible media loss occurs when air scouring and backwashing at prescribed rates.  Ortho-Wash™ troughs with baffles are constructed of either 304 or 316 stainless steel to provide durability and maintenance-free service.
