ACTOPENTIN® biofiltration
Efficient cleaning of polluted air streams

 

Biofiltration is ideally suited for removal of organic solvents and unwanted odors from polluted air streams. Conventional biomasses are compositions of wooden chips, bark, compost and other fibrous, all natural components. These filter masses have significant disadvantages, compared to the newly developed ACTOPENTIN® biofilter mass, which is also composed from only natural ingredients.

Air cleaning with ACTOPENTIN® biofiltration means:

More than 5 times higher cleaning efficiency

Substantially lower space requirements

Cost savings in both investment and operation

No need for sophisticated system control and instrumentation

No expensive water processing and irrigation subsystems

Modular construction, integrated in standard containers

Low maintenance and high design life span of more than 5 years

Covered by patents worldwide

BIOFILTER COMPARISON

 

Conventional biofilter

ACTOPENTIN® biofilter

Composition

heather, fibrous peat, compost,
bark products, coconut fibers,
wood chips

proprietary and patented mixture
of grape seeds, minerals and
other additives

Internal structure

not homogenous, internal
changes during service life

constant and stable, no changes during service life

Operational safety

depending on many factors

established and fully reproducible

Adaptation time

8 - 25 weeks

2 - 8 weeks

Temperature range

20 - 40 deg C
70 - 100 deg F

10 - 70 deg C
50 - 160 deg F

Filter resistance

800 - 2,000 Pa

100 - 600 Pa (0.4 - 2.5 in/H2O)

Moisture

low moisture
must be kept fairly constant

high moisture
large range variations permissible

pH value

hyperacidity may occur due to internal generation of sulfuric
or organic acids

acids and bases are buffered and balanced within the biomass

Dry out effects

lasting severe damage to biomass

no effects after re-moistening

Condition

added water forms sludge

no sludge formation even after extreme over-moistening

Maintenance

dig up of biomass at least once
per year but always after
dry out or over-moistening

structure maintained internally, no dig up or other rework required
over service life span

Service life

1 - 3 years
material use: rot of biomass

5 years min.
low material use of organic components

Summary

- biomass system with low stability
- ventilation characteristics change
- life time cycle not sufficient
- high maintenance and control

- stable and reproducible system
- optimized and stable ventilation
- high life time cycle
- low maintenance and control

 


ACTOPENTIN® applications

Major applications for biofilters may be found in:

Food processing:

Coffee and cocoa roasting, meat and fish processing, breweries, slaughterhouses.

Agriculture:

Livestock breeding, fodder production.

Manufacturing industry:

Whenever heavy air pollution and/or odors are generated such as in pulp and paper industry, furniture manufacture, plastics production and processing, chemical, petrochemical processing, pharmaceutical, paint, lacquer and varnish industries.

Sewage treatment plants:

Any size and application (industrial and municipal)


Unwanted odor bearing VOC's are removed with the following efficiencies:

Hydrogen sulfide (93 - 95%)

Mercaptans (> 98%)

Ammonia (90 - 97%)

Carboxylic acids (95 - 99%)

Ethers (> 95%)

Amines (> 97%)


Organic solvents within the following groups may be treated with similar high efficiencies:

Alcohols

Aldehydes

Ketones

Carboxylic acids

Aromatic hydrocarbons

Thioethers

Ethers

Mercaptans

Esters

Amines

Above cleaning rates are typical for average concentrations of pollutants, derived from applications or lab tests within the system specifications. These values may vary from site to site and should give an estimate for the high efficiency of the ACTOPENTIN® Biofilters.
