Wastewater treatment for the dairy industry

Did you know that the dairy industry is the largest producer of wastewater within the food industry? By processing just 1 m3 of milk, up to double the amount of wastewater is generated. Most of this comes from cleaning processes. In addition, dairy wastewater contains raw materials from spills and tank unloading operations.

But what exactly covers the sector? Dairy processing covers the transformation of raw milk into several products such as pasteurized milk, yogurt, cheese, butter, and ice cream. The global consumption of these goods is huge and ever-increasing. And so is the amount of wastewater produced.

Dairy wastewater is characterized by a wide variability in composition and flow, partly due to over production and seasonal spikes. Up to 90% of the organic matter in dairy wastewater comes from the milk components, such as fat, proteins, and lactose. As a result, dairy wastewater is highly biodegradable, with BOD5 and COD ratios up to 0.8. 

In conclusion the dairy industry has a high impact on the environment and thus regulations are leading to high disposal costs. To overcome this there is a real need for more advanced technologies, such as biological treatment with ultrafiltration membranes. There are three main reasons to decide which technologies fits best: The tighter discharge limits and taxes, growing need for water reuse and the water scarcity in some regions. 

Challenges for wastewater treatment in the dairy industry

Variability

High variability in quality and quantity of wastewater.

High levels of BOD and COD

Which need to be reduced before discharged to municipal treatment facilities.

FOG

Presence of FOG and dissolved salts. ​

Toxicity

Presence of cleaning and sanitizing products, with potential toxicity and inhibitory effect.

Hampering

Poor sludge settleability, hampering the conventional activated sludge processed

Tubular membrane solutions for dairy wastewater treatment​

Managing the variability of dairy wastewater, while maintaining the effluent quality required for discharge or reuse can be a real challenge. Thus the implementation of advanced and robust biological treatment technologies with tubular membranes can make a real change. 

Tubular UF membranes are known to provide the reliability and robustness required for treating the high-loaded dairy wastewater. Nowadays, more than 20 million m3 of dairy wastewater are treated every year with external MBRs based on Berghof tubular membranes. Some of these installations are anaerobic MBRs in waste – to – energy systems, promoting a more sustainable dairy activity day after day. 

Worldwide leading OEMs specialized in the dairy industry have put their confidence in Berghof’s technology. Milk, cheese, butter and other dairy factories are using our technology with great success.
