HUBER Micro Strainer ROTAMAT® Ro9 Wastewater screen for small to medium flows

  • With integrated screenings washing and compaction
  • For channel installation or supplied in a tank
  • With optional frost protection for outdoor installation

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 HUBER Micro Strainer ROTAMAT® Ro9 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 HUBER Micro Strainer ROTAMAT® Ro9 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.

Design and Function

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 machine starts to operate when a certain upstream water level is exceeded due to screen surface blinding.

A robust stainless steel 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 without any odour annoyance prior to discharging them into the customer‘s container or a subsequent conveying unit.

The HUBER Micro Strainer ROTAMAT® Ro9 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 and also available with optional frost protection for outdoor installation.
