Industrial effluents


To take full advantage of his art, and also to continue to consider environmental protection, GEA provides the brewer with powerful centrifugal separating technology systems. For many reasons, centrifugal separating technology has become established in breweries as a forward-looking solution for waste water treatment.


Advantages of separation technology in breweries

Separation technology from GEA has many advantages: decanters and separators operate continuously, are extremely efficient for clarification and separation, and require minimum energy and personnel. Treatment installations for the entire waste water system can operate in extremely restricted spaces and require the minimum of up-front costs.

Reducing costs, boosting the yield

Brewery waste waters mainly consist of two streams: residual substances from production. Yeast, fermentable sugar or kieselguhr, for example, can be recycled as valuable substances into the production process once solid and liquid components have been separated. This reduces costs and boosts the yield.

The second main stream of brewery waste water comes from the cleaning of fermentation and storage tanks as well as vat and bottle rinsing. Decanters have proved to be extremely efficient for removing these residues and cleaning agents thereby making a specific contribution to environmental protection and to reducing disposal costs.

Dewatering environmental Decanter prime

Decanter compared with sedimentation under gravity

It also makes sense to use a decanter after the anaerobic or aerobic treatment of the production waste water in the works’ waste water treatment plant. Compared with sedimentation under gravity, the decanter exerts a force on the solids particle that is four thousand times higher, resulting in much faster separation. The sludge removed by the scroll is dewatered and compacted; the smaller volume of solids makes disposal easier and less expensive.
