HUBER Disc Filter RoDisc® is a micro screen filtration system designed to remove fine suspended solids from water and wastewater. Uses up to 35 vertical discs with mesh sizes as small as 10µm. Operates as a gravity-flow system with up to 65% of disc surface submerged during use. Mesh is thermally fixed and segments are individually replaceable.

  • Micro screen filtration system for fine solids removal from water and wastewater
  • High hydraulic throughput on a small footprint
  • Gravity system with low headloss, no need to lift wastewater
  • Continuous operation during cleaning cycles
  • No external water supply needed for backwashing, uses filtrate
  • Individual filter segments can be replaced without lifting equipment
  • Reduces filterable solids, COD, BOD, and phosphorus
  • Can be installed in stainless steel or concrete tanks

Applications

  • Filtration of biologically treated wastewater in municipal and industrial plants
  • Pre-filtration for UV disinfection or membrane filtration systems
  • Process and service water treatment in industry
  • Drinking water recovery from surface waters
  • Removal of microplastics and helminth eggs
  • Technical road runoff treatment
