LEVAPOR carrier are comprising of, porous, flexible, easily fluidisable plastic foam cubes, impregnated with adsorbing pigments. They
  • can adsorb remarkably quantities of organic substances,
  • become colonized very fast by specialized microorganisms and
  • bind up to 300 % water,
  • resulting in bioprocesses with remarkably higher efficiency and stability,
  • regenerating the adsorbing capacity biologically.

Due to the versatility of polymeric foams, carrier dimensions and properties can be varied within wide limits.

Depending on bioprocess and reactor type, LEVAPOR carrier can be applied in fluidised , expanded and fixed bed reactors, respectively in biotrickling filters for following bioprocesses:
-   Biotreatment of  municipal and industrial effluents , especially in
  • nitrification and denitrification
  • anaerobic and aerobic treatment of complex effluents and 
  • removal of persistent and hazardous pollutants and micropollutants.

-   Biological gas treatment in bio-trickling-filters (BTF) including acidifying
    pollutants, like chloroorganics, mercaptans, NH3 and H2S.
-   Processes reusing water, like fish hatcheries and aquacultures.
-   Fermentation of bioproducts.

  • Higher efficiency and stability of bioprocesses  under
  • Lower excess biomass production
  • Lower degree of reactor filling : only 12 to 15 vol.% instead of 30 to 70 % as usually practicized  in reactors with non modified plastic carriers
  • Higher removal of persistent, hazardous pollutants via
  • Buffering of toxic shock loadings
  • Short startup period of bioprocesses
  • Remarkable process economy
  • Simple technology, applicable also during plant operation and
  • Proven technology with several references.

Additionally  to LEVAPOR carrier  we do offer also our services in designing of  taylor made problem solutions, based on  40 years experiences on biofilm technologies both in science and practice :
  • Analysis of the problem
  • Elaboration of alternatives for problem solution , supported by
  • Practice oriented  biotests (optional),
  • Process Design and/or Engineering
  • Production and delivery of the required LEVAPOR type and
  • Plant startup using optimized mixed biomass, enriched with microbes essential for degradation.

LEVAPOR products are surface activated, adsorbant porous foams.

By coating polymeric foams with surface active pigments modified foams with new, variable properties can be obtained.
The modified properties result in :

  • Foams with fine or large pores.
  • Higher , adsorbing surface and water binding capacity
  • Variable density, settling velocity, ionic charge and conductivity.
