Industrial Wastewater Treatment ? out with the old and in with the new!

The Malteurop group is a world leader in the malt industry and is positioning itself as the first market integrator of the barley-malt-beer value chain. At it?s Geelong, VIC processing plant, the existing wastewater treatment facility was in need of an upgrade. With decades old biological treatment consisting of batch reactors, it was identified the most important issue to address was the aeration system.

Waterform Technologies collaborated with Malteurop to develop a solution with the leading OTT Fine Bubble Air Diffusers to replace the existing disc aeration grids.

Malting wastewater is a challenging wastewater to treat, with very high BOD, COD and organic loading. It particularly poses a challenge for submerged aeration systems. Waterform was able to successfully install the leading OTT Fine Bubble Silicone Air Diffuser system which exhibit excellent anti fouling properties and a long life-span, and are designed for wastewater.
