KCH designs and manufactures a Biotrickling Filter System to remove high levels of hydrogen sulfide (H2S) gas and other odors from municipal and industrial. KCH Engineered Systems designs and manufactures a Biotrickling Filter System to remove high levels of hydrogen sulfide (H2S) gas and other. A biotrickling filter is a combination of a biofilter and a bioscrubber. The process of biotrickling filtration is, as is also the case with biofilters and bioscrubbers.

In order to keep the activity of microorganism and also save energy, air and nutrient solution could be stopped and only supplied at regular intervals, which could reduce the time for restart.
Hence, periods of starvation associated with a decrease of biomass would not decrease the lifespan of the biotrickling filter.
However, in most cases, inlet concentrations and volumetric loads of H 2 S were relatively low and thus shock loads were also relatively mild. The carrier material is constantly covered with water. A biotrickling filter is a combination of a biofilter and a bioscrubber.
Odor mainly composed of hydrogen sulfide H 2 S from the pharmaceutical wastewater treatment plant is one of the major public perception nuisance problems in the pharmaceutical industry. Under proper filte, biological process ibotrickling highly efficient and environmentally friendly.
Van de Meulebroecke1, P. Transient response of biotrickling filter to fluctuating H 2 S after re-acclimation. Inlet H 2 S concentration was kept at a relatively high value at the re-acclimation process without ramping up.
Optimieren der biologischen abluftreinigung VDI Inorganic Media Guaranteed for 10 Years. The surface must have a structure that allows biomass to bond to it effectively. The present research described the results of a bench-scale study investigating the effects of H 2 Fliter starvation and shock loads on biotrickling filter performances.
The filter material consists of synthetic foam, lava or a structured plastic packing. Contact us today, for one of our design engineers to evaluate your application and determine the optimum design parameters for your installation. Solid thiosulphate agar biotricklign was made as follows: It should also be noted that a decrease in the biomass was not vital at relatively high biomass concentration.
In the starvation experiments, liquid biotridkling velocity was controlled at a relatively low value once per hour, with 3 L of nutrient solution to supply necessary nutrient materials for microorganism and decrease the effect of liquid shear stress on the biomass. The airflow rate was kept at 6. H 2 S was introduced into the biotrickling filters biotdickling the bottom after flowing through the flow meter and the treated gas exhausted from the top.

The pH can be continuously measured and corrected. Biotrickling filters are used for applications in which there is no space for a biofilter, where the efficiency of a biofilter is not sufficient, or in the presence of ph-relevant compounds. KCH offers a non-proprietary nutrient supplement to feed the micro-organisms and water to maintain the optimum pH.
Biotrickling filter response to shock loads In order to further study the acclimatization of the bioreactor to shock loads, the bioreactor was supplied with H 2 S of variable concentration after resuming normal operation. Botrickling biotrickling filter is, in fact, a three-phase biocatalytic oxidizer and is essentially made from a support carrier on which microorganisms are able to grow when optimal biotricklnig are provided.
The Biotrickling Filter System can include additional components needed to provide a complete functioning system, such as: VAT Case study 3: Biotrickling Filters Biotrickling filters are used for applications in which there is no space for a biofilter, where the efficiency of a biofilter is not sufficient, or in the presence of ph-relevant compounds.
In the industrial operation of biotrickling filters for hydrogen sulfide H 2 S removal, shock loads or starvation was common due to process variations or equipment malfunctions. Auxiliary materials Nutrients to feed bacteria Suppletion water to compensate for discharge and vapour losses.
Owing to the variable industrial schedules, pilot-scale or full-scale biotrickling filters are usually exposed to many perturbations as a result of fluctuation or discontinuous shock loads.
Biotrickling Filter Systems
During dimensioning it is important to set the load at a modest level in order to avoid such blockages. Filtter momentary response of the bioreactor to these abrupt changes in inlet concentration is presented in Fig. Re-acclimation processes of four starvation experiments were similar after restarting biotrickling filters.
KCH Biotricklers can also be designed for a rectangular low-profile configuration, utilizing a structured high-density media. In the biotrickling filter, the packing may become blocked due to strong growth in the biofilm. In this study, effects of starvation and shock loads on the performance of biotrickling filters for H 2 S removal were investigated.
Biofilters and Biotrickling filters | SOS Hygiene
One must be careful when buffering spray water. The supply of H 2 S was stopped in the biotrickling filters during the starvation experiments.
Support Center Support Center. The most widely utilized bioreactors for air pollution control are biofilters and biotrickling filters. And the biomass did not drop to a level where biodegradation efficiency would be limited during the starvation experiments. The biotrickling filters with an inner diameter of mm and a height of mm were made of transparent plexiglass tubing.
