ROTAMAT® Screens

Screening – Washing – Transport – Dewatering in one unit

Based on the ROTAMAT® principle "screening – washing – transport – dewatering in one unit" a complete ROTAMAT® family was developed and successfully launched onto the worldwide wastewater treatment market.

All ROTAMAT® screens work according to the unique and patented system that has been sold for more than a thousand installations worldwide. Depending on the screen size and bar spacing throughputs of up to approx. 3000 l/s (10,800 m³/h) per unit can be achieved. The screens can be installed into either a channel or tank. They are space-saving as they combine several functions - screenings separation, washing, transport and dewatering - in one system.

The machines are completely made of stainless steel. Their unique principle ensures maximum separation efficiencies and maximum throughput.



Case Studies



All ROTAMAT® Machines offer outstanding advantages

  • The rotating operation principle reduces wear to a minimum.
  • Integrated screenings press, no odour annoyance, low disposal costs
  • Optional integrated screenings washing reduces disposal costs.
  • Installation directly into the channel without a step in the channel bottom possible.
  • Easy retrofitting
  • Insensitive to grit, gravel, stones
  • Completely made of stainless steel
  • Minimum maintenance as the screens do not have reciprocating parts or reversal points
  • High separation efficiency through flow diversion
  • Low hydraulic resistance through the big free passage area
  • Self-cleaning machine and screen basket
