The technology of biological exhaust air

of water-soluble, microbiologically degradable
contents of the air.

The contaminated air flows through a matrix
colonised by micro-organisms which absorbs
hazardous contents and subsequently oxidises
them through metabolic processes.
An intelligent spraying system keeps the
micro-organisms wet and also supplies them
with nutrients and minerals according to

industrial scale and to further develop this
technology to its current state through
continued research and development.

be further optimised with regard to structure
and coating for your individual application. Apart
from dwell periods of less than 20 seconds and
a considerable increase in process reliability
(shock-loading conditions resistance), these
bio-filters guarantee a service life of up to
10 years at a constant pressure loss without
any signs of subsidence or compression.
Furthermore, they reduce the required space by
up to 50% compared with similar filters that make
use of organic carrier materials.

SeRVice & oPeRATion
As with other technical systems, the efficient
functioning and efficiency of a biological
exhaust air cleaning system depends
decisively on the method of operation and the
system maintenance. We therefore offer you a
comprehensive range of services covering all
aspects of optimal operation of your plant.
Our employees will offer you friendly, reliable
and competent support in the optimisation and
adaptation of technical processes to changing
production conditions as well as providing
current information about changing legal
situations.
We examine the microbiological and
physical-chemical state of your carrier material
and monitor the temperature and humidity of
your plant using the state-of-the-art
measurement and control technology
connected to our 24-hour service centre. In this
way, we can identify problems at a very early
stage and ensure safe and cost-effective
operation throughout the entire plant life cycle.
We are at home anywhere that exhaust air
cleaning problems must be solved. We build
and support systems for the widest range of
industrial and municipal applications.
