Waste gas treatment for a recycling tetra pak plant
We installed a biofilter and wet scrubber to eliminate VOCs and odour that are emitted from the waste warehouse and the treatment process. The system has a capacity of 18 000 m3/h
Client: an international corporation
Location: Poland
Project duration: 8 months
Completion date: April 2023
More about the project
Client asked to eliminate waste gas and odour emitted from their brand-new recycling line in a proven and sustainable way. Therefore, a biofilter with a wet scrubber was the solution that fits the scope, while activated carbon and plasma based solutions were not chosen.
Fan and air ducts
Our team of specialist carried out the installation of a fan and air ducts according to the volume of waste gas to be treated (18 000 m3/h)
Packed bed wet scrubber
We manufactured and installed a packed bed wet scrubber with a capacity of 18 000 m3/h. The scrubber regulate the moisture balance of the biofilter bed and remove or decrease the non-biodegradable or semi-biodegradable compounds and eliminate any particulates (PM) from the polluted gas stream. Our scrubber has a body made of UV-resistant HDPE (high density polyethylene), the surface is smooth, UV‑radiation, weather and corrosion resistant. It is automatically controlled and it is equipped with a heating system for preventing freeze damage during the cold season.
Biofilter
The biofilter includes a biological active bed or filling (mixture of crushed husk, peat or similar materials and specific micro-organism) under which several grids are installed to equally distribute the polluted waste gas across it. The pollutants are adsorbed and metabolized by specific micro-organisms’ enzymes into carbon dioxide, water, inorganic salts, biomass and energy.
As the contaminants are decomposed and not just absorbed, the biofilter bed retains no residues from the original organic compounds present in the contaminated air stream. To improve the performance of biofilters, Dekonta provides the DEKONTAM-3© a biopreparation that includes bacterial cells, residual nutrients after fermentation, and a mineral fertilizer.
