Orthos - Header-Lateral Underdrain

Used in pressure vessels and in legacy concrete-tank media filters, the header-lateral underdrain is a manifold system consisting of one or more larger-diameter header pipes, each with numerous smaller-diameter lateral pipes extending typically both horizontally and perpendicularly on both sides of the header pipe.  ORTHOS manufacturers pipe saddles to mount nozzles directly onto the lateral pipes and concrete sleeves for manifold-embedded designs.  Nozzles with tailpipes are offered for header-lateral systems utilizing air scour.
