Chemical combi air scrubbers
The chemical combi air scrubber is a comprehensive version of the traditional chemical lamella air scrubber. The chemical combi scrubber is designed with an additional biological cleaning filter. The use of a second filter wall greatly reduces both ammonia emissions and odour and fine-particle emissions. In this system the stall air goes first of all through the set of lamellae with acidified washing water, then through a drop collector, then through a second filter stage that uses a plastic filter and biological washing water. The biological operation removes odours and dust particles from the stall air.
The discharge water from the biological stage can possibly be used to supplement the washing water from the chemical stage. The chemical combi air scrubber has an ammonia reduction of 85%, an odour reduction of 70% and a fine-particle reduction of >90%.
According to the European certificate, the dust reduction is even over 95%. The chemical combi scrubber is certified in both The Netherlands, BWL2006.14.V3, and Germany, DLG certificate 5880. Naturally the chemical combi scrubbers are fully fitted with an automatic flushing function and an electronic data logging system with Internet preparation.
