Task
Molkerei Niesky GmbH, located near the Polish border, specializes in the production of a wide range of high-quality cheeses. The product range includes Edam, Gouda, Emmental, mozzarella, cagliata and a variety of other first-class cheese products.
Due to the naturally high pH value of the whey produced during our production processes, careful neutralization of the waste water is essential.
Design data
The wastewater to be treated consists of rinsing water from cheese production and has a pH value in the alkaline range.
Waste water volume:
- max. 700 m³/d
Target parameters:
- Neutralization of the pH value
- Intermediate storage with biodegradation
Solution & implementation
We have built a 700 m³ mixing and equalization tank (MAB) for efficient intermediate storage of the rinsing water from our production facility. This tank is filled by a powerful double pumping station. The MAB is continuously aerated and is always half-filled with wastewater. This measure promotes the colonization of aerobic microorganisms, which effectively break down a considerable proportion of the organic compounds.
Due to the naturally high pH value of the whey waste water, we have integrated a two-stage CO₂ neutralization system into an ALMA module. In this system, the pH value is automatically and precisely reduced to a neutral level.
