Exhaust air purification and heat recovery systems are generally not standard applications, even if individual assemblies are now modular. We have made it our goal to offer our customers the best solution for their task. To do this, we take a step back with our customers in order to gain an overview of the whole. Together we look at how the exhaust air is generated and try to start our concepts right at the point of origin. Only then can we decide which exhaust air system is the most economical when considering the total cost of ownership and compliance with the limit values. Should an extended consideration be necessary, we can accompany you from basic to authority to detail engineering. In addition, it is not uncommon for pilot tests to be offered, which lead to the later real scale of the systems by means of scaleup. With these consulting and engineering services, we offer you a manufacturerindependent package with which you can make the right decision for your company.

In many incineration and industrial plants in various industries as well as in the municipal sector, dust emissions are produced during production processes. These emissions must be purified before they are released into the atmosphere. The dusts can be sticky, greasy, wet, dry or combustible and have different particle sizes. In general, they are between 0,1 and 1000 μm in size. Dust collection systems physically filter these dusts out of the exhaust air. WesselUmwelttechnik specialises in various methods of exhaust air cleaning, including industrial dust collector systems, to safely comply with legal requirements, e.g. the German TA Luft. In addition to dry filtering, the product range includes wet separators. This way, even humid and hot exhaust air as well as agglomerating dusts can be treated by the Wessel systems. The various exhaust air purification technologies allow the use of dust collecting systems in a wide variety of industries.

If no procedures for biological or chemical exhaiust air cleaning are to be used efficiently, the thermal treatment is regarded as method of choice. The basic thermal processes are Recuperative thermal oxidation Regenerative thermal oxidation Catalytic oxidation. The focus of our products lies particularly in the periphery of especially challenging special solutions Waste treatment Sewage sludge drying Waste water treatment Landfill aftercare Specialpurpose solutions for the chemical industry Food industry In general at corrosive media, at risk of condensation, and especially high specifications for the pure gas Since 2018 we are working close with our sister company Airprotech Srl. from Magenta/Italy in the field of thermal exhaust air cleaning. Beside our core products our range of products in the field thermal exhaust air cleaning is broadened Airprotech is specialised in the development, the manufacture and the supply of turnkey plants for thermal cleaning

Biological exhaust air cleaning is used whenever exhaust air has to be cleaned from volatile organic compounds (VOCs) and odours. Biofilters play a major role in this process. The polluted exhaust air is passed through a filter medium where the VOCs and odours are separated. Normally, this medium is an organic carrier material where microorganisms are grown on. They convert the VOCs and odours into noncritical components by means of their metabolism. Especially regarding the removal of odorous substances, biofilters are a very efficient and comparatively inexpensive way of biofiltration with an efficiency of up to 99 %. BIOCATbiofilters have a high degree of efficiency in a wide range of applications, even for exhaust air components that are difficult to dissolve in water.

Biological exhaust air cleaning is always required if exhaust air needs to be purified of volatile organic components the socalled VOCs or odorous substances. The demand for biological procedures has increased in recent years. On the one hand, biological exhaust air cleaning does not generate any climaterelevant greenhouse gases. On the other hand, it meets all legal requirements for clean gas values. With over 200 biological exhaust air cleaning processes installed, Wessel has comprehensive practical knowhow and is the technology leader in the field of biological exhaust air cleaning. The biological exhaust air cleaning systems have been continuously optimised and further developed by WesselUmwelttechnik for decades. The modern cleaning systems from WesselUmwelttechnik work efficiently. Thanks to the continuous monitoring of the plant parameters, they require only a minimum of operating effort.
