Carlsberg, Falkenberg - Sweden

Falkenberg's breweries, located alongside the River Ätran produce almost 300 million litres of beer, soft drinks and mineral water per year.

Carlsberg's primary focus is the production, sale and marketing of beer, with secondary activities in soft drinks and water production. Carlsberg has a major stake in several large European breweries, such as Carlsberg UK, Carlsberg Sweden, Ringnes (Norway), Feldschlösschen (Switzerland), Sinebrychoff (Finland) and Carlsberg Polska (Poland).

In 2004 Carlsberg closed its brewery in Stockholm and moved the production to Falkenberg. The capacity in Falkenberg was thus doubled and produced larger quantities of highly COD loaded effluents. The municipal wastewater treatment plant couldn't cope with the increased load.
A new pretreatment line to reduce load to acceptable level was necessary, and had to be in operation by the beginning of 2005, when the new part of the production facility was to be put into operation.

Veolia Water Solutions & Technologies' Swedish subsidiary Krüger Akvapur built a new pre-treatment line based on anaerobic technologies. The project covered : design, equipment supply, supervisory assistance during installation and commissioning.

Veolia Water Solutions & Technologies' offer included the Biopaq™-IC anaerobic reactor, one of the best available anaerobic technologies. Veolia Water Solutions & Technologies Poland and Krüger's experience and knowledge of anaerobic technologies were key factors in Carlsberg's decision to choose Veolia Water Solutions & Technologies.

The Biopaq™ IC anaerobic technology produces biogas for reuse as an energy source in the production facility. Sludge production is minimised and any sludges produced may be sold to other treatment plants requiring this specific type of biological sludge.

The compact installations fit into to the limited space available and meet the client's requirements.

The project management resulted in a short installation time. The plant was commissioned in January 2005, meeting the project's time frame.
