Installation of Biolac system is first for Cargill in Australia

The city of Tamworth in New South Wales, Australia, recently imposed new and more stringent limits on nutrient and biological oxygen demand (BOD) discharge levels. To improve environmental performance and wastewater quality in preparedness for the more new regulations, manufacturers such as Cargill are investing in improved water treatment technologies to dramatically improve the quality of effluent water that is discharged following their operations.

Parkson's advanced biological treatment system was selected by Cargill Australia following a competitive bid process that included domestic and international suppliers. Parkson's Biolac system was the winner. This first Australian installation for Cargill follows successful applications of the Biolac system at numerous Cargill locations in the United States.

The installed Biolac provides simultaneous nitrification and denitrification and biological phosphorous removal, saving Cargill on additional capital and creating an easy-to-operate plant for the local operators. The combined processes, coupled with a completely automated design, help Cargill to save dramatically on its operating and maintenance costs and to deliver an improved water quality from its facilities.

Parkson's Biolac can be installed, as it will be for Cargill, in lined earthen basins, eliminating the need for concrete construction. The system's low energy requirements can be traced to its patented moving diffuser system, which requires approximately one-third of the energy needed by fixed diffuser systems. The system's energy efficiency also will deliver benefits to Cargill's energy usage, allowing it to make progress toward corporate energy efficiency goals set at a global level. Additionally, the patented WaveOx denitrification process further lowers energy use by more than 30%.
