Whether it be municipal or industrial wastewater treatment, the Fournier Rotary Press represents an innovative change in sludge dewatering. The benefits derived from using the Fournier Rotary Press have been well documented and are translated into huge savings for the customer by means of performance, operation and maintenance. 

The Fournier Rotary Press is at the heart of the dewatering process, completed by sludge and polymer feed systems. The principle of operation is simple. Sludge is fed into a rectangular channel, and rotated between two parallel revolving stainless steel chrome plated screens. The filtrate passes through the screens as the flocculated sludge advances within the channel. The sludge continues to dewater as it travels around the channel, eventually forming a cake near the outlet side of the press. The frictional force of the slow moving screens, coupled with the controlled outlet restriction, results in the extrusion of a very dry cake.

The benefits include:

  • Continuous operation
  • Totally enclosed
  • Low power usage
  • Low noise level
  • High cake dryness
  • Easy start-stop procedures
  • Small footprint
  • Low wash water requirements

In addition to their rotary press, Fournier also provides:

  • Polymer feed systems
  • Shaftless screw conveyors
  • Sludge blenders
  • Other accessories
