HUBER ROTAMAT® Vortex Grit Chamber VORMAX - brochure ...

➤➤➤ Design and functionGrit separation from wastewater helps preventoperational problems such as grit sedimentation,increased wear and blockages. The screenedwastewater enters the VORMAX at the bottom of thegrit chamber where a tangential rotational movement isgenerated due to the curved vortex chamber. Aconstantly rotating stirrer helps support the wastewatercirculation within the grit chamber ensuring a constantvelocity of rotation within the complete grit trap system.Additionally, a baffle plate installed radially around thestirrer induces an axial flow towards the centre of thegrit chamber. Due to the constant radial rotation andaxial flow the solids are very quickly collected within thecentre of the grit chamber from where they then passinto the bottom of the grit collection tank. The grit-freewastewater then flows over a weir onto the nexttreatment step.Centrifugal or airlift pumps can then deliver thecollected solids from the grit collection tank into a gritclassifier or grit washer where the solids can then besubsequently separated and dewatered and organicparticles removed.➤➤➤ The user's benefits➤ Compact, space-saving design➤ High grit separation efficiency➤ Low energy demand➤ Throughput capacity up to 3000 l/s➤ Low pressure loss➤ Optional concrete tank design➤ Minimum wear, reduced maintenance➤ Optional subsequent grit washing➤➤➤ Installation exampleFlow diagramwashed gritscreeningsCOANDA Grit Washerwastewater fine screengrit trapHans Huber AGMaschinen- und AnlagenbauPostfach 63 · D-92332 BerchingTelephone: + 49 - 84 62 - 201 - 0Telefax: + 49 - 84 62 - 201 - 810e-mail: info@huber.deInternet: www.huber.deSubject to technical modificationHUBER ROTAMAT ®Vortex Grit ChamberVORMAX1,2 / 1 – 8.2005 – 8.2005
