Removal of unpleasant odors is especially important when the odor emitter, e.g. in a sewage treatment plant or
processing plant, is close to inhabited areas. The specific smell of pollution and dangerous chemical compounds that are
formed during wastewater treatment or production can significantly affect the comfort, well-being and sometimes health
of people.
The BIOROK® system is not only a biofilter, but also it is combined with the technology of adsorption of pollutants on
active carbon. The biological bed and the sorbent are located in closed chambers, thanks to which the weather conditions
do not affect their function. The BIOROK® system uses the LAVA-ROK type bed, produced utilizing natural volcanic pumice,
or another equally highly effective mineral bed, to which special microorganisms are inoculated in the technological
start-up stage. The fan forces the polluted air through the bed. After leaving the biological chamber, where more than
90% odor reduction is achieved, the air passes to the second stage of purification, which is a sorbent - a bed of
special, high humidity resistant, active carbon. Here the gas is cleaned, achieving an almost 100% reduction of
odor-generating substances. Thanks to this combination of both methods, it is possible to use the carbon bed many times
longer than with standard carbon filters, and at the same time achieve better cleaning efficiency than with standard
biofilters.
The use of this innovative technology, being the BIOROK® system, brings many benefits. As with other biofilters, the
EKOFINN-POL system does not require constant maintenance. Appropriate design makes the biofilter reliable at all times
of the year - regardless of weather conditions, the device not only remains operational, but also does not corrode. The
plant room with the fan is placed in a soundproof casing, which successfully suppresses the noise associated with the
operation of the biofilter. The dimensions of the device allow for installation also in small municipal and industrial
facilities. BIOROK® is almost completely automated - the automation independently controls the parameters of the process
(temperature, humidification, dosing of nutrients) so that they are optimal and adjusted to the demand. In the event of
irregularities, the system will provide information about them to the user, which is an additional convenience during
operation.
The system enables continuous measurement of the main odor-producing gases (hydrogen sulphide, ammonia) at the inlet and
outlet of the device. Each of the plant items can be equipped with the MONITEL® monitoring system, which allows for
remote online readings of odor-producing gases with data archiving.
