Retrofits of concrete-tankage, granular media filters are perfect applications for MAXIMUS, though because of its relatively-quick installation, new, “greenfield” applications are certainly deserving of consideration.
After filter leveling, the perimeter frame of MAXIMUS is secured using anchor bolts using HILTI epoxy. A gasket is placed between the perimeter frame, floor, flume support angle, and flume end plug, as necessary, to seal the bottom perimeter of MAXIMUS. Nozzle plates are secured to the filter floor using square anchor tubes with epoxied anchors. Span plates with gaskets are bolted through the nozzle plates and into nuts that are factory-welded to the underside of the nozzle plate. Nozzle plates and span plates extend over the perimeter frame and are connected with bolts and gaskets to further seal the top of MAXIMUS. The thick, 10-gauge stainless steel perimeter frame, nozzle plates with its robust stiffeners, and anchors will withstand a minimum of 1600 lbs/ft2 uplift force.
