When Noosa first began making yoghurt, the plant was able to mix dairy wastewater with manure and apply it to land as a fertilizer. As production increased, this method of wastewater disposal became unsustainable, so Noosa made the environmentally-responsible choice of investing in an on-site wastewater treatment solution. A reliable solution that would adapt to varying flows and wastewater characteristics, comply with strict environmental regulations, while generating an effluent suitable for reuse on-site or direct discharge, was a must!


Evoqua's wastewater experts worked with a local engineering firm on the overall design and installation of the wastewater treatment system. An equipment package supplied by Evoqua was integrated into the plant design.

The system was sized and designed with expansion in mind. As demand for Noosa products continued to increase, the company soon realized that wastewater production would quickly exceed original projections. The future design flow would be generated much sooner than expected, and the increase in permitted discharge flow meant that Noosa would need to meet stricter discharge limits on nitrogen and phosphorus. Noosa then contacted Evoqua to supply a second prefabricated membrane tank in order to double the treatment plant capacity, as well as evaluate the overall MBR system process design in order to achieve biological nutrient removal.
