Cooling tower for cooling and aeration of wastewater flow
Gramybel, part of the Mydibel Group, was looking for a new cooling tower for a wastewater application. The Mydibel Group is a potato processing family business located in Mouscron.
As a large potato processor, Gramybel has a constant flow of wastewater. They cannot discharge the water without meeting certain conditions. The corrosive character of wastewater can affect the concrete in the sewers.
Gramybel's wastewater flow contained hydrogen sulphide (H₂S). By aerating and cooling the wastewater using a cooling tower, the hydrogen sulphide oxidizes to SO₄⁻²-sulphate. Sulphates are much less corrosive than sulphides and therefore less harmful.
Gramybel decided to use an open counterflow cooling tower type Almeco AIR. The cooling tower made of fibreglass reinforced polyester is made in accordance with the applicable Legionella legislation. Thanks to a large access hatch, inspection and maintenance can be carried out safely and quickly.
