Advanced wastewater treatment and biogas energy for Arla Dairy


In response to Arla Dairy's ambitious goal of establishing the world's first zero-carbon fresh milk processing facility, our team implemented an innovative solution combining advanced wastewater treatment and biogas energy.

At the heart of this project lies the Memthane® AnMBR, a technology developed by our subsidiary, Biothane®. This Anaerobic Membrane Bioreactor not only effectively removes up to 99% of chemical oxygen demand (COD) but also maximizes energy and water recovery, contributing to Arla's carbon-neutral objectives.

By treating 500 cubic meters of wastewater daily and utilizing a patented mixing system reactor, our solution has not only achieved an average total COD removal of 99.4% but also generated biogas for an on-site combined heat and power (CHP) plant, ensuring sustainable and environmentally responsible dairy operations.
