Hager+Elsaesser GmbH (H+E) has been awarded three contracts totaling €6.4 million to provide wastewater treatment plants for sugar refining plants in the MENA region.
The sugar industry uses flume water circuits for the cleaning of processed crops.
Abundant lime is added to the flume water prior washing the sugar beets, which reduces odors and results in a better settling of soil.
In addition, the lime reduces corrosion in the pipework and therefore keeps maintenance and service costs down.
However, it also results in wastewaters with high calcium content and a tendency for mineral precipitation, which can rapidly clog the equipment and degrade performance of the overall treatment process.
H+E will supply a two-stage process known as ANAFIT.CS, based on the anaerobic contact sludge process.
An Aquarion Group, H+E said this overcomes the limits of conventional wastewatertreatment systems in dealing with these very large amounts of calcium carbonate precipitates.
These contracts follow the earlier award of a €3.3 million contract by a leading beet sugar production plant in Poland. Now in operation, that plant has completed successful operations in both campaigns, or production cycles, since its commissioning.
Thomas Will, CEO of H+E, said: “The rising demand for sugar around the world, coupled with growth in the number of projects that we have recently won, is certainly sweet news for our company.”
