Liqson helps ab inbev with recycling of groundwater

Water reuse is an increasingly prominent topic. A growing number of stakeholders are also realising its importance in the brewing world.  AB InBev’s Stella Artois brewery in Leuven is strongly committed to this and is counting on Liqson to help facilitate this process by providing suitable buffer tanks, pumps and instrumentation.

WELL DRAINAGE

On construction sites it is common practice to apply well drainage (or dry suction). The contractor pumps up the groundwater in order to excavate the earth. Both developer AG Real Estate and construction companies MBG and Democo wondered whether the water could be put to good use, instead of simply discharging it into the sewer. In some cases, local residents or farmers like to use this water to water plants and trees. Given the size of a site on Artoisplein, those responsible went in search of a larger customer, which they found on the other side of the square.



AB InBev set up an installation on the site next to their office to pump up the water. The pumped water is transported to the brewery via pipes under the intersection of the Artoisplein. There it undergoes a purification process, so that it can be used in production as process water. The efficient use of water is essential for AB InBev, also for social purposes. For example, the brewery donates the treated waste water to the City of Leuven green service.

Buffer tank

Liqson was asked to provide the temporary buffer tank into which the groundwater enters.

“Using two stainless steel HCP pumps, the water is pumped from the rental tank to the brewery. We designed and developed this set-up and control in collaboration with Pompen Reynaert. (www.pompenreynaert.com) Because the supply of groundwater is not constant, there was an overflow, which drains the water that the brewery does not need into the Dyle river. We tested this set-up thoroughly beforehand to ensure a reliable solution,” says Emiel Sobry of Liqson.

TELEMETRY SYSTEM

These buffer tanks can be equipped with a level measurement or telemetry system. This telemetry system ensures that the volume can be consulted online at all times. In addition to this instrumentation, Liqson also provides the necessary piping, flexible hoses, coupling pieces and other accessories.
