### In this Case Study

Learn how Veolia delivered a solution based around a Memthane® AnMBR system that treats 500 cubic meters per day of wastewater, removing up to 99.4% of chemical oxygen demand (COD). This integrated approach enables our clients to achieve carbon neutrality while maintaining efficient dairy operations.

Read on to find out how we:

- Created the world's first zero carbon fresh milk processing facility
- Achieved 99.4% average total COD removal from wastewater
- Successfully implemented water recycling by treating low-strength wastewater and grey water through reverse osmosis for reuse in dairy operations
- Established energy recovery by using biogas generated from the treatment process to fuel an on-site combined heat and power plant
