Extra high air scrubber exhaust up to 12m
To meet the special conditions of the permit, the combined biological air scrubber was built in on top of the unloading area and fitted with an extra high exhaust to the 12m high ridge. CBgroep built two custom air scrubbing units that were connected to a centralized control room. The barn with 4,950 slaughter pigs also has inlet filters. In order to minimize the operating costs, a drain flow reactor, type Draineater, was installed on the washing water circuit, reducing the discharge volume by 85% on an annual basis. In addition, the residual nitrogen deposit in the drain water will also decrease by 60% compared to biological scrubbers without washing water treatment.
