The present day intense competition, brought with it the demand for optimal cost effective solutions. The chemical Process Industry is no exception to this.

There is ever increasing demand for:

  • Improvement in productivity
  • Reduction in energy consumption
  • Superior product Properties
  • High Yield
  • Avoid emission

Rotofilt with its decade long application engineering competence in solid-liquid separation, ever committed to Research. Innovation is one of the foundation stones on which the Rotofilt’s strength lies. The aim of such activity is to develop most cost effective, new products with improved quality levels, most efficient performance and on line producing around the clock.

To address the needs of Chemical Process Industries Rotofilt developed a simple and a reliable design for its Automatic Vertical Pressure Filter. The end result is the most efficient and economical solution for solid-liquid separation.

Rotofilt’s test facilities are available for Laboratory and pilot scale testing.

The test filtration produces dewatered solids and filtrate samples with slurry obtained directly from the client’s process.

Reliable test result are used for proper dimensioning of the filter as well as projecting all process and cost benefits in the application in question.
Design Features
  • The horizontal plate design results in even distribution of slurry, wash liquid and most effective air penetration with no risk of cake cracking.
  • Fully automatic which results in consistent performance in terms of throughput i.e. higher productivity.
    Once downstream and upstream equipment are integrated with optimized process parameters. It will lead to highest quality products, with lowest moisture and highest yield.
    No operator required, eliminates exposure of operator to chemical and equipment.
  • As the driest cake is produced of all filtration methods, lower energy costs as it eliminates or reduces the requirement of dryers.
  • Ultra filtration wash system eliminates plant effluent system.
  • The machine can be built with features confirming to explosion proof standards.
  • Based on service requirements non-corrosive, corrosive or highly corrosive application, machine can be built with various stainless steels & high strength materials.
Mode Operation
  • Filtration
    With a push of a Button, Filter Plates close, closed chambers are formed. Pressurised pumping of slurry into all chambers simultaneously takes place. As filtrate permeates the filter cloth, cakes are formed.

  • Squeezing
    Water at a high pressure fills all chambers, inflates diaphragms squeezing the already formed cakes with 4 to 5 times higher pressure than feed pressure.

    Tightly woven filter cloth allows for higher pressure and increases filter efficiency.

  • Cake Wash
    As the plates are horizontal, wash liquid is evenly distributed for uniform cake washing.


  • Post Wash Squeezing
    Water at a high pressure is pumped in simultaneously to all chambers, squeezing all the wash liquid through cakes with “total displacement wash” wash, thus achieving very high efficiency.

  • Air- Blowing
    Compressed air is blown through cakes in all chambers simultaneously by adjusting the air pressure and flow further minimizes the moisture the cake moisture can be further minimized.


  • Cake Discharge & Cloth Washing
    All filter plates in the plate pack open simultaneously and with the advancement of filter cloth all filter cakes are discharged automatically. Both sides of the filter cloth is washed with high pressure water to clear the cloth sieves of any binding solids.
