Noggerath® Rotary Drum Screen RSH-M / RSH-MG

The separation of very fine solid particles from water and wastewater using state-of-the-art micro screening technology.

The Aqseptence Group offers you versatile micro screening drum systems with proven results as being both effective and economical in a wide range of applications.

Unique Selling Point

  • High flow rate and low headloss due to optimal hydraulic characteristics using curved screen panels
  • Integrated emergency overflow
  • Blades installed in the screen baskets prevent screenings from falling back into the raw water
  • Direct drive by means of a gear wheel

Insights

The heart of the Noggerath® Rotary Drum Screens RSH-M / RSH-MG is a rotary drum consisting of sieve baskets which are connected with each other. The system can be installed either in a concrete chamber, a stainless steel or plastic tank. With our RSH-MG-D design we integrate additional key features as they relate to the growing demand for water and wastewater treatment and also the increasing application of membrane technology like screenings pressing and drum sealing to avoid solid.

The micro screening drum system offers an effective and very economical alternative to conventional screening technologies in municipal wastewater applications.

Technical data

The raw water passes through the screen drum cage from the inside to the outside, leaving solid particles on theinner surface of the screen. The resulting buildup on the screen surface blinds the mesh openings causing a pressure loss across the screen. When a defined difference is detected between the upstream and downstream water the drum begins to rotate. During the rotating movement, the screen mesh is backwashed with an external sprayingdevice. This spraying device is located in the apex of the micro screening machine. The cleaning of the screen panels improves the filtration performance and reduces the water level differential, resulting in the drum stopping its rotation.
The cleaning water and screenings are directed out of the drum via the internal launder channel, a screenings press or a spiral conveyor.
