Press Filters

Filtros de Prensa PKF 250 NG2 Putsch Nerva

The Putsch® press filter systems are part of the standard equipment used for decades by the sugar and sweetener industries. 

Over 1,000 press filters have been successfully installed and commissioned throughout the world. Putsch® products are known worldwide in filtration and environmental technology industries, and in all plants dedicated to the production of glass and sugar, thanks to their quality and reliability. 

The high degree of diversification achieved by Putsch® is the result of constant innovation.


Manufacture of Pigments and Dyes

Many applications in this industry require a reliable service 24/7. A corrosive environment, high temperatures and an often unstable atmosphere require a suitable design. The Putsch® filtration systems were created to meet these requirements. Conventional systems such as drum filters and centrifuges have been satisfactorily replaced by press filters. 

   Typical applications:

  • Titanium dioxide (TiO2) (finish/desalination and waste/neutralization)
  • Caustic soda
  • Acids
  • Coatings

Food and Agriculture Industry

Putsch® press filters and juice purification systems are standard applications for the sugar industry. A high performance design and a high level of automation make these filters the ideal choice for many applications in this market.  

   Typical applications:

  • Wine and juices
  • Beer
  • Edible oils
  • “Green Energies” (Bioethanol)
  • Animal waste
  • Sugar and sweetening processes

Chemical and Petrochemical Industry

Putsch® press filter systems offer extensive capabilities with fully automated process for the industry. Corrosion and abrasion-resistant materials and a solid design for 24/7 operation make these filtration systems the ideal choice for this market. 

   Typical applications:

  • Calcium carbonate (CaCO3)
  • Barium sulphide (fluid finish)
  • Silicates (product and waste)
  • Polymers (fibres)
  • Brine solution (recovery cooling)

Mining and Minerals

The demand for large capacity press filters for harsh environments makes Putsch® press filter systems, with their innovative cake unloading system, an economical option for this industry. 

   Typical applications:

  • Mineral concentrate
  • Flotation sludge
  • Coal
  • Clay (kaolin, bentonite, ceramics)

Recycling and Environment

For this type of industry, Putsch® offers various press filter designs, in addition to assistance in development in our test laboratory.

   Typical applications:

  • Stone processing(cutting, gravel polishing and washing applications)
  • Plastic fibres(carpet recycling)
  • Power plants (flue gas desulphurization, REA)
  • Industrial waste
  • Chemical waste 

Pharmaceutical Industry and Biotechnology

The demand for carefully controlled processes and clean environments can be met with Putsch® press filter systems. Our software and enclosures meet this challenge. 

   Typical applications:

  • Yeast
  • Biosolids
  • Algae
  • Blood plasma
  • Enzymes

Pulp and Paper

Although centrifuges are the preferred option as dehydration equipment in this industry, press filter systems have achieved better results with regard to the rate of capture of solids, final moisture content and salt removal (cake washing).

   Typical applications:

  • Green liquor (soda recovery)
  • Coating waste treatment
