Advice on discussions with authorities, development of a solution to reduce unpleasant odors, installation and commissioning the solutio

Renovation of the water system will eliminate the strong and unpleasant odor of the brewery wastewater, which develops in the mixing and equalizing tank. As a result, employees and visitors will be spared embarrassment. In addition to the economical treatment of wastewater, a new discharge permit will be applied for.

Keep wastewater fresh through the introduction of oxygen and avoiding sedimentation. Additional optimization of neutralization.

PWT supported and advised the Ganter brewery in the application for a new discharge permit. Furthermore, a solution was developed to reduce the odor of the wastewater in the mixing and equalizing tank. The installation of frequency-controlled jet aerators keeps the waste water "fresh" and prevents sedimentation. The control is dependent on level and oxygen to achieve an optimal cost-benefit ratio. Furthermore, the pH value is kept within the limit values by pumping cycles adapted to the operation and optimised mixing as well as NaOH dosing.

In addition, the NaOH dosing was optimized to improve neutralization.
