Air scrubbers are often part of the fixed/mandatory equipment in agricultural (such as lifestock farming) and agro-industrial companies. However, these air scrubbers often show unsufficient performance, resulting in numerous complaints about odor nuisance. Usually, these problems can be solved quite easily, at an acceptable cost.
We are specialized in the optimization of air scrubbers or other installations with insufficient separation efficiency. Is goes without saying that completely new installations are possible as well. This both in the field of odor nuisance and in the field of separating harmful components out of gazeous emissions (biogas installations, sludge digesters, manure processing, intensive livestock farming).
Our working method
After thorough sampling and analysis, we proceed, in consultation with the customer, to the necessary interventions to limit the odor nuisance for the neighbourhood as much as possible. We assess which optimizations are needed on a case-by-case basis. This is where our many years of expertise and know-how in air purification and odor control are of great value.
Of course, it is also possible to consult us for advice. Subsequently, you can carry out the necessary interventions yourself, with our help if needed.
How does an air scrubber work?
Air scrubbers are one of the most frequently used equipment for air pollution control and odor control. In an air scrubber, the unwanted components are separated from the gas and absorbed into the liquid. Inside the column there are filler bodies or packing to maximize the efficiency of the scrubber. The washing liquid consists of water with added chemicals. The composition of the scrubbing liquid depends on the nature, initial concentration, composition of the components to be separated and the predetermined efficiency of the air scrubber. Air scrubbers are available for small as well as for large flow rates.
Air scrubbers consist mainly of the following components: washing tower (packed column), filling bodies (structured or random packing), drip tray, nozzle(s) or liquid distributor, pump, chemical dosing, measuring and control equipment (pH, redox) and a water replenishment system.
Custom made gas scrubbers
Our air scrubbers are always custom made and specifically designed for the specific emission flow. For each application, the design is adaptable regarding capacity and changing production process circumstances, within certain limits. Of course, all air scrubbers are designed to fit seamlessly into the existing situation.
The advantages of a gas scrubber
- relatively simple and well controllable
- low energy consumption
- compact and space-saving
- predictable and guaranteed efficiency
- high separation efficiency
- versatile, for many agricultural and agro-industrial applications
Maintenance of existing gas scrubbers
Task is also your partner for the maintenance of gas scrubbers. In case you are not sure anymore about the efficiency and/or functioning of your air scrubber, please contact us. Together we will discuss the possibilities and if necessary we plan a site visit.
Replacement of packing and internals
The correct selection of the packing and other internals of a gas scrubber is specialist work. This selection will determine whether or not your gas scrubber system will function properly. Clogged, compressed packing will increase the pressure drop over the gas scrubber and decrease the efficiency of the system. We take care of the replacement of the packing and/or other internals. We always look for the best type with optimal efficiency for each specific application.
Also the various measurements of pH, redox, conductivity are taken into account and adjusted if necessary. We have already optimized several air scrubbing installations, to meet the standards for odor removal efficiency and separation of harmful substances from the emission flows.
Heat recovery from gas scrubbers
Most types of gas scrubbers can be optionally equipped with a heat recovery system. As a result, green energy from your exhaust air can be recovered, allowing you to save on your company’s energy costs.
