Filtration material Filtralite

What is Filtralite

Filtralite is a filter material designed for the treatment of drinking and processed water and for tertiary stages of wastewater treatment plants. It is produced by a patent process from clay by firing and sintering at a temperature of 1200 ° C.

Filtralite is suitable for open, pressure and biological filters. ENVI-PUR is the exclusive supplier for the Czech Republic and Slovakia. 

Filtralite along with a drainage system Leopold and provides the best of what is in the water and sewage filtration currently available in the world.

Advantages of the Filtralite filter

The Filtralite Mono-Multi (FMM) or Filtralite Mono-Multi Fine (FMMF) cartridge allows you to easily convert single-layer filters to double-layer filters without changing the washing intensity.

  • Optional material density

  • Use of lower washing speeds

  • High resistance to grain abrasion

  • Use of lower washing speeds

  • High sludge capacity

  • Lower pressure drops

  • Better quality of treated water

  • Energy saving and washing water

Properties of the Filtralite filter

Optional density

  • Density can be selected in the range of 1050 ~ 1800 kg / m³
  • The grain size can be selected in the range of 0.8 ~ 20 mm
  • Use in single- and double-layer filters
  • Unique double-layer filling Filtralite Mono-Multi and Mono-Multi Fine
  • Lower selectable density of the upper layer compared to conventional materials

Partially porous structure

  • Used in classical and biological filters
  • Used in removing iron and manganese

Other features

  • High sludge capacity (up to 4 times higher than the production of filtrate sand filling)
  • Specific surface properties of grains - improve the capture of suspensions from treated water
  • Higher resistance to grain abrasion compared to anthracite or hydro anthracite

Try Filtralite and compare…

We offer test models to verify the suitability of using Filtralite filter material on raw water.

The results of the comparative studies of other contents and Filtralite were presented at a number of professional conferences.
