Biotrickling Filter

Biotrickling filter is a device that converts organic matter into carbon dioxide, water and heat using the principle of adsorption and decomposition of microorganisms.

Exhaust gas treatment technology that deodorizes the molecular structure of odor by using the microbial membrane on the biological filter filler.

Core Parameters

Capacity	0-20000 m3/h
Material	FRP/PPH
Packing Media	Biofiller, Coconut Bark, Pine Bark, Adsorbed Carbon, Lava Rocks

Features

Strong application adaptability: By adding thermal insulation layer and cooling system, biological trickling filtration can be applied to various environments and temperatures.
Application: Suitable for a variety of inorganic and organic odors, including NH3, H2S, mercaptans, thioethers, amines, alcohols, aldehydes, ketones, etc.
Stink gas.
The process is simple and the operating conditions are low: biodegradation can be carried out at room temperature.
Low equipment investment and low operating cost: The biological trickling filtration process only needs a biological box and a circulating pump to start working.
Low investment and almost no additional operating costs.
Secondary pollution, pollutants are degraded by microorganisms into non-toxic and harmless small molecular substances such as CO2, H2O, inorganic salts, etc.
Optimize the growth environment of microorganisms, promote the growth of microorganisms, and improve the efficiency of biodegradation: by adding and replacing nutrient solutions, adjust the
The pH value and temperature of the microbial growth environment can be controlled, so that the metabolism of the microorganism can be kept active, so as to maximize the biological
Filtration efficiency. The tunability of the growth environment of microorganisms is the distinguishing feature of biological trickling filtration from other biological filtration technologies.

Application

The biotrickling filter has a good deodorizing effect for those odors with low concentration of pollutants, large quantities and good biochemical properties. Taking advantage of the low cost and good controllability of biological trickling filtration, it has been successfully applied in many industries:

Feed processing plants (fish meal processing, meat and bone meal processing)
Processing plants (slaughterhouses, intestines)
Fertilizer plant
Brewery/Fermentation Room
Food Processing Plant
Industrial, municipal sewage station/pumping station
Sludge drying
Biopharmaceutical Room

Working Principle

Biotrickling filter for waste gas streams containing VOCs and odorous compounds is more cost effective and environmental-friendly than conventional air pollution control technologies.

In a biofilter, the pollutants are biologically degraded by aerobic microorganisms to stable end products like CO2, H2O, sulfate, microbial biomass, etc.

The simple equation for microbial degradation of odor is as follows:
