AFOTEK Anlagen für Oberflächentechnik GmbH - Biological Air Purification Systems

THE PROFESSIONAL FOR
BIOLOGICAL AIR PURIFICATION SYSTEMS

To protect the environment, the pollutants from gases and vapours produced during painting must be cleaned before exhaust air is released into the atmosphere. Since thermal cleaning systems are neither emission-free nor energy-saving, biological exhaust air purification using microorganisms is the ideal solution for removing pollutants from high exhaust air flows in a cost-efficient and environmentally friendly manner.

Advantages of AFOTEK's biological exhaust air purification systems

Environmentally friendly process to minimise pollutants (biofilter)
Low space requirement (optimal use of operating space)
The system can also be placed outside the production hall
Individually configurable (modular principle)
Alignment with customer needs (flexible adjustment of system capacity, system size and volume flows)
Low energy costs (required solely for controlling the system and preheating the aqueous solution)
Low maintenance effort thanks to fully automated control technology (control cycles and maintenance times are significantly reduced)

Operating principle of biological exhaust air purification

An essential component of biological exhaust air purification systems are two cylindrical silo containers filled with a moist carrier material, which act like a
biofilter. The mechanism of action is based on the use of aerobic microorganisms that biochemically convert the gaseous, organic pollutants into harmless and odourless compounds (biological oxidation). In contrast to conventional, thermal solutions, this purely biological-chemical process for exhaust air purification requires hardly any external energy, is therefore both cost- and resource-saving and does not pollute the environment.

1. Supply of contaminated exhaust air to the exhaust air purification system

2. Enrichment of atmospheric oxygen in a first cascade.

3. Absorption of the exhaust air ingredients in an aqueous phase through chemical-physical processes or direct adsorption on the biofilm.

4. Biological oxidation of the exhaust air contents largely to water, carbon dioxide and biomass by microorganisms.

5. Leakage of clean air from the exhaust air purification system.
