Liquid filtration/separation

Versis (Niagara) filters

Filtration Group's Versis filters are the further development of the traditional Niagara filters - pressure filters for cake filtration with a large filtration area. The filters have double sided, stainless filter leaves installed on which the filter cake is built up. The solid filter leaves have five layers of wire mesh consisting of three coarse support meshes and two fine filter meshes in stainless steel. 

The filters are supplied in either carbon steel or in a range of stainless materials.

Typical applications:

Animal fat, bleaching earth filtration, gelatine, glucose, nickel catalyst, pectin, process water, rapeseed oil, water glass etc. ​

Cricket filters

Ama/Filtration Group's Cricket filters are pressure filters with stainless filter elements, which look like cricket bats (hence the name), on which a filter cloth is mounted. The filter cloths are available in several materials which make the Cricket filter suitable for basically all types of liquid filtration applications.

Typical applications:

​Animal fat, gelatine, glucose, nickel catalyst, pectin, process water, water glass, vegetable oil etc.


  • ​Cricket®filters for dry filter cake (filtration area up to 100 m2)
  • Cricket®filters for wet filter cake (filtration area up to 250 m2)
  • Complete fully automatic filtration systems

Cartridge filters

Filtration Group's cartridge filters are most often used for verification filtration or for polishing of prefiltered liquids. But are also suitable as main filters for certain applications. As our filter cartridge product portfolio consists of approx. 4,000 types it is almost always possible to find an optimum solution for a given application. 

The cartridge filter housings are available in carbon steel, stainless steel or plastic.

Bag filters

Filtration Group's bag filters are most often used for verification filtration or for polishing of prefiltered liquids. As the filter bags can be delivered in many different dimensions and materials, they are suitable for various applications.  

The applications are numerous, e.g ink/varnish/paint, chemicals, process water and vegetable oils.

The bag filter housings are available in carbon steel, stainless steel or plastic.

The filter bags can be delivered in many different dimensions and materials. Nominal selectivity between 0.5 - 800 micron.

The bag filters (without filter bags) can also be an economical alternative to large basket strainers.

Liquid solid separators

The Russell Liquid Solid Separator is suitable for removal of fine particles from liquids. The centrifugal force of the impeller provides the machine with the ability to achieve high capacities even on fine meshes. It is possible to separate down to 5-10 microns depending on the liquid type.

Examples of applications:

  • Dairy products - recovery of curd
  • Cider drinks - removal of solids from apple juice
  • Wool scouring - removal of fibres from wash water
  • Vegetables - removal of peels from the waste water

Examples of capacities

Wash water:      100,000 l/h at 100 micron 

Starch liquid:     15,000 l/h at 100 micron 

Whey:               42,000 l/h at 40 micron

Self-cleaning filters

Russell's self-cleaning filters are designed to remove small amounts of particles from all liquid types while the unique SpiroKlene™ wiper device keeps the surface of the filter element clean. The self-cleaning filters are available in both vertical and horizontal versions with either the traditional wedge wire element or filter element with defined holes down to 10 microns. These self-cleaning filters are also a good and user-friendly alternative to the traditional bag/cartridge filters. Furthermore the filters are very easy to clean as most of the types can be disassembled or assembled in less than two minutes (see video below) thus also reducing downtime. 

See interactive video of self-cleaning filters from Russell

The self-cleaning filters are available in 3 versions:

Horizontal online filter design:

Disassembly and cleaning time are further reduced. Ideal for installation in plants with limited height available. 

Vertical online filter design:

The flow principle operation eliminates dead points and provides high capacity.

In-line filter design:

This type is easily installed in existing piping.

​Furthermore the filters are available in many different sizes and in different versions - e.g. jacket for temperature-sensitive products, incl. control systems, high-temperature filters, mobile systems etc.

FLSmidth Krebs hydrocyclones are used in many industries for separation, concentration and dewatering of particles and liquid or liquid-liquid separation.

In principle hydrocyclones work with all non-emulsions, where there is a difference in density between the liquid and what needs to be removed. Hydrocyclones can be used as an independent separation unit or in front of other separation units such as centrifuges or filters, where the hydrocyclone thus reduces the size of the following equipment. 

The hydrocyclone can be constructed in many different materials such as different types of metal, ceramics and plastic depending on the process and the surroundings. 

Guideline for particle/liquid separation:

  • Separation from approx. 5 µm
  • ​Minimum flow approx. 150 l/h
  • Natural separation in a beaker at max. 10 minutes
  • No flocculation agent added

Guideline for liquid/liquid separation:

  • Natural separation in a beaker at max. 5 minutes
  • No chemical emulsion
