“Osmoflo will provide a key new element in the company’s integrated water treatment and management system. The new plant will increase the flexibility and capacity to treat contaminated water at the Ranger mine, generating release water quality consistent with the highest standards of environmental protection during rehabilitation activities.” Peter Anderson, Technical Studies Manager at ERA.

Challenge Energy Resources of Australia required further water treatment at the Ranger site  to help maximise the conversion of contaminated waste water to water for environmental release.

In partnership with ERA, Osmoflo conducted extensive pilot studies prior to this contract award to ensure the right solution is delivered to ERA to solve their unique water requirements.

Solution  The project will include a 3,000 m3/day OBS plant in 3 trains, with BWRO polishing of the water to meet stringent environmental discharge standards. Osmoflo is responsible for installation of the complete plant in a shed, including all mechanical and electrical integration to ERA infrastructure

The contract includes operations and maintenance of the plant, which is expected to operate until all processing and major rehabilitation activities cease at the mine.

This is the third major installation by Osmoflo at the Ranger site since 2008, with the continued relationship illustrating ERA’s trust in Osmoflo’s water treatment solutions, and strengthening Osmoflo’s credentials in ‘difficult-to-treat’ water applications.

Result  This will be a significant OBS installation for Osmoflo and ERA, with construction of the plant expected to be completed by the end of 2018.
