With its unique porosity, Filtralite® Pure filter media offers optimum conditions for water to flow through the filter bed in order to retain and adsorb more contaminants. This feature, main characteristic of the lightweight expanded clay material, allows for larger volumes of water to be filtered through the same volume as contact area is increased.

Water management facilities can thereby increase their output without having to rebuild and expand existing facilities simply by replacing the conventional filtering media with Filtralite products.

 

Filtralite® in mono and dual granular media filters for an improved physical filtration

Filtration of water is the most traditional type of water treatment. Filtralite has the ideal properties to work as a good filter media in both mono and dual media filters for filtration of raw or coagulated water. 

Compared to traditional filter media like sand and anthracite, Filtralite has much higher porosity, which gives

  • lower initial head loss,
  • slower head loss build up,
  • higher storage capacity,
  • and lower backwash rates.

These advantages result in much longer filter runs between backwashes, which means reduced energy and water consumption and higher water production, consequently giving reduced operating costs. 

Filtralite solutions can be implemented in mono media filters, as well as in in dual media solution (Filtralite Mono-Multi and Filtralite Mono-Multi Fine) in which two types of Filtralite Pure filter media with different densities and sizes are combined, improving even more filter runs and production capacity.

Filters with Filtralite can be operated within a large range of filtration rates. The filtration rate will always be dependent of the configuration of the filter and the treatment process. Existing Filtralite filters operate from up to around 20 m/h.

 

Filtralite® as a biofilm carrier in fixed bed water treatment process

Filtralite Pure is also excellent for treating, in fixed bed water treatment process, raw water containing ammonia, manganese, iron etc.

Compared to other media, Filtralite has much higher porosity, which gives

  • great specific area for biofilm growth,
  • high number of macropores,
  • lighter density,
  • and high resistance to abrasion.

Existing biological Filtralite filters operate up to 30 m/h.

With its unique porosity, Filtralite® Clean filter media offers optimum conditions for biofilm growth and for water to flow through the filter bed in order to retain and remove more contaminants. This feature, main characteristic of the lightweight expanded clay material, allows for larger volumes of water to be filtered through the same volume as contact area is increased. Our products also decrease operation costs.

 

Filtralite® as a biofilm carrier in fixed bed water treatment process

In biological filters, biomass is fixed to the Filtralite media, which also works well as a mechanical filter for suspended solids.

Filtralite Clean offers:

  • great specific area for biofilm growth combined to high void ratio,
  • high number of macropores,
  • a very efficient process on volumetric bases,
  • lighter density than traditional media,
  • and high resistance to abrasion.

 

Filtralite® in tertiary granular filters for an improved physical filtration

Filtralite Clean is also excellent for tertiary filtration.

Compared to traditional filter media, Filtralite has much higher porosity, which gives

  • lower initial head loss,
  • slower head loss build up,
  • higher particle storage capacity,
  • lower backwash rates,
  • and lower operational costs.

Existing Filtralite filters operate around 15 m/h - 20 m/h.

Filtralite Air

Pure air is a necessity for comfortable living. Odours from industry, farming, and wastewater treatment can be purified with biofilm in bio filters.

With its unique porosity, Filtralite® Air Filter Material is conducive to biofilm growth and allows air to flow through the filter bed in order to retain and adsorb more odours. This feature allows for larger volumes of air to be filtered through the same volume as contact area is increased. Our products also decrease operation costs due to high storage capacity and low pressure loss over time.

Filtralite® Air filter media is an innovative and premium filtering product tailored to meet tomorrow’s needs.

 

What is the advantage of using Filtralite® Air Filter Material?

  • Stable structure – does not collapse
  • Durable and resistant natural clay mineral material without any hazardous or artificial components.
  • Low weight means reduced construction, filling and removal costs. The horizontal and vertical pressure on walls and structure is 5 times lower than that of ordinary mineral materials.
  • Defined product – Well-defined grading.
  • Good storage capacity for biofilm and excellent permeability results in low pressure loss and long service life.
  • Large surface area results in an efficient carrier for biofilm.
  • Water reservoir – the porous structure absorbs and holds water which improves the efficiency of water trickling.
  • An adsorbent with good properties will help bio-filtration. Filtralite Air Filter Material has sorption capacity towards H2S so the filter will start removing odour even before the biofilm is established.

The simple principle of treating odour is to pump the gas through a filter media upstream or downstream with water sprinkling.

Filtralite® Nature is a fine grained filter material, made of expanded clay, with large surface area and a high capacity for phosphorus removal in water

Phosphorus is removed by both precipitation at high pH and physical-chemical attraction and bindings. Filtralite Nature products are tailored to provide large P-sorption capacity, achieving a high degree of phosphorus removal.

When the removal capacity is exhausted, the filter material can be replaced. The used material can be used as fertilizer or soil conditioner.
