Successful trial of airstream scrubbing in the food industry

Outside vs inside of a Drupps test rig tested on-site inside an industrial facility ridden with high air particle content for three weeks showing no particles managed to pass through the Drupps system despite thick layer build-up on its outside.

Drupps has concluded a study of its scrubbing capabilities showing strong ability to function as a wet scrubber.

The purpose of this test was to study how well a Drupps system prevents dust and other airborne particles from passing it. The test site was a factory in the food industry, whose operations involve evaporation of large volumes of water. This drying costs a lot of energy, as well as water, both of which the factory is aiming to recycle as efficiently as possible.

However, the exhaust air also carries very high levels of nutrient-rich particles, causing clogging as well as moulding in the current recycling systems. The current systems have reached their end-of-life and are in need of replacement.

The results from the study show zero carry-over of dust through the Drupps system, with a complete removal of airborne particles from the airstream.

The inside of the Drupps test rig was as shiny as on deployment, in contrast to its outside where a thick layer of dust and moulding had formed during the same period. The airborne debris was caught, collected, and removed by Absium and its filtration system as solid waste.

In conclusion, Drupps system's value creation comes not only through enabling recycling water and energy from airborne airstreams, but also through cleaning of the airstream. This creates opportunities for further air treatment downstream with no or limited risk of clogging.
