Dewatering and
Water Clarification Expertise
Effective handling of the solids generated by clarifier or thickening operations has been an ongoing problem waiting for a good solution. Centrifuges, belt presses, screw presses, plate compression devices and other techniques have all been less than stellar in their ability to cost-effectively produce a high solids product that is easily handled.

The Fournier Rotary Press is an evolutionary step in the dewatering of slurries and sludge to form cake material.

Many of the practical applications include:

  • Primary Sludge
  • Mixed Primary/WAS (digested and biological sludge)
  • Biological sludge for composting (amendment added)
  • Septage sludge
  • Primary (digested)
  • Pulp and paper clarifier sludge
  • Brewery
  • Agricultural
  • - Pig manure
    - Cow manure
  • Organic solids recovery
  • Food process
  • - Milk transformation
    - Bagasse
  • Plastic recycling
  • Rolling Mill
The Rotary Press uses very little energy – a single press unit has a 5 HP (3.7 kW) motor while a 6 press unit has just a 20 HP (15.0 kW) motor.

The Rotary Press requires very little maintenance –few moving parts and slow rotating speed.

The Rotary Press has an automated self-cleaning cycle – it uses very little water during a 5 minutes/day purge.

Consistently High Cake Solids – High Capture Rates – Robust Construction
