ROTAMAT® Complete Plant Ro 5HD

Complete Plant with Hydro Duct

  • Well-proven mechanical preliminary treatment equipment
  • High grit separation efficiency
  • Optional separate grease chamber with grease removal
  • Compact, space-saving unit

The Ro 5HD Complete Plant combines the benefits of both aerated and unaerated grit traps by using a high-performance grit trap with a small overall plan area. The wastewater flows firstly through an inlet screen that retains, washes, compacts and dewaters the solids contained within the flow.


The screened wastewater passes into an aerated grit trap that reduces the settlement of organics within the flow by the action of an aeration system within the grit trap. Grease along with other greasy material is collected in a separate integrated grease trap chamber from where the grease is automatically discharged by a well-proven paddle system.

The flow then enters a second unaerated upflow grit trap chamber which contains an integral hydro duct that ensures a directed flow approach from the bottom of the chamber with positive and uniform upflow distribution.

The flow velocity in the unaerated grit trap chamber is reduced to such an extent that very fine grit is easily and reliably separated. Whilst the separated particles are removed from the grit trap by classifying screws, they are simultaneously being statically dewatered prior to being discharged into a container.
