HUBER Micro Strainer ROTAMAT Ro9

Waste Water Combined Inlet screen for flows upto 220 l/sec

HUBER Micro Strainer ROTAMAT Ro9

  • Two dimension screening with washing and compaction Single low kW drive
  • Suitable for channel or tank mounting
  • Over 1100 UK installations

The Challenge – Our Solution
Both municipal wastewater treatment plants and industrial applications require mechanical treatment as a first treatment step to remove as much as possible of the floating, settling and suspended material.  
The aim is to achieve the maximum separation efficiency under the prevailing hydraulic conditions.  
Operating reliability, efficiency and hygienic operation are important factors for a mechanical separation plant.  

The ROTAMAT® Ro9 inlet screen operation is based upon a unique system that allows combination of screening, washing, transport, compaction and dewatering in a single unit.  

Depending on the screen bar spacing or perforation and screen size (up to 700 mm screen basket diameter), the throughput can be individually adjusted to specific site requirements.
The ROTAMAT® Ro9 Inlet Screen is completely made of stainless steel and acid treated in a pickling bath.  

The screen can be installed either directly in the channel or in a separate tank.

Key benefits

  • Low Investment Costs
  • Single low kW drive
  • Screening washing and compaction in a single unit Full stainless steel construction
  • Brush wear sensor to indicate brush replacement may be necessary
  • Quick and easy installation even as a retrofit
  • Low washwater consumption
  • Can easily incorporate a bypass screen
  • Control panels designed and built in the UK
  • Frost protected for outdoor installation Intermediate bearing to prevent damage from potential  lack of maintenance

Whilst the wastewater flows in through the open front end of the screen basket and through the screen bars or perforations, solids are retained by the screen basket, whereby the separation of floating, settling and suspended solids is dependent upon the screen bar spacing or perforation size.

Blinding of the screen surface generates an additional filtering effect so that solids can be retained that are smaller than the bar spacing or perforation.  
The screen starts to operate when a preset upstream water level is exceeded due to screen surface blinding.

A robust stainless steel shafted screw removes the screenings from the screen basket surface.  
Additional cleaning is achieved by wear-resistant brushes fitted to the screw flights. The screw conveyor transports the screenings through a closed and inclined pipe.
Whilst the screenings are transported, the screw conveyor dewaters and compacts them prior to discharging them into the skip, wheelie bin or conveyor.
