          <p><span style=\"font-weight: 400\">The Flexscour Underdrain was originally developed as a retrofit system that would be sufficiently flexible to accommodate any existing pipework and tank arrangements without compromising efficient flow management. The same qualities have come to be make Flexscour a reliable underdrain for new water treatment plants.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Flexscour underdrains do not require false floors \u2013 they are an anchored system, not a grouted system. This ensures rapid, straightforward installation, ideal for rehabilitating older filters.<\/span><\/p>\n<p><span style=\"font-weight: 400\">The Flexscour Underdrain has the additional features and benefits:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400\">Uniform cleaning achieves peak filter performance<\/span><\/li>\n<li><span style=\"font-weight: 400\">Rapid, straightforward

          <p><span style=\"font-weight: 400\">Most header and lateral underdrains attempt to regulate backwash flow with variably sized orifices. However, traditional hydraulic models have proven inadequate for accurate sizing in areas of higher header flow velocity. The Flexscour Underdrain designers conducted exhaustive tests to gain a better understanding of the relation between crossflow velocity and turning resistance. These tests yielded a superior set of orifice sizing guidelines and an unequaled level of backwash uniformity.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Typically, air is supplied from an overhead steel pipe while filtrate and backwash water flow through a concrete floor channel and primary orifices in lateral baseplates. A variety of feed and drainage arrangements are possible, depending on existing basin layout, with distribution orifices specifically sized for each application to ensure flow equalization. Lateral orifices are covered by stainless steel shields. The entire assembly is fastened to the filter floor with stainless steel anchor bolts.<\/span><\/p>\n<p><span style=\"font-weight: 400\">The Flexscour Underdrain eliminates the surging wave action commonly responsible for media migration in combined air and water backwash systems. By partitioning lateral ducts into separate channels for air and water, the tendency of uneven pneumatic pressures to create reciprocating waves in header\/lateral underdrains has been eliminated. Air distribution is uninterrupted, allowing vigorous, uniform cleaning with no media displacement. Where simultaneous air and water backwashing can be used, effective media cleaning can be accomplished with a fraction of the water required in alternating flow arrangements.<\/span><\/p>\n\n
