Desalination solution for several source water intakes

A newly developed flotation process which forms part of the minerals recovery process at the Mount Weld rare earth mine near Laverton in WA is sensitive to water quality. Overcoming that problem a 2.3 megalitres per day (ML/d) reverse osmosis desalination plant is now supplying the mine with water to the consistent standard required. The plant has been financed, built and is being operated by Osmoflo through a of a 10-year Build Own Operate contract. It has been designed to concurrently treat water from two different sources and of vastly different quality. The primary source is saline bore water (5,600 mg/L Total Dissolved Solids) which also contains high levels of magnesium and silica. Both can be detrimental to the performance of some reverse osmosis membranes so special consideration was given to the selection of the most appropriate membrane type for this project. Following treatment, TDS content is less than 150 mg/L. Some feed water is also sourced from a tailings dam. To cope with the differences in feed water characteristics from each source, the plant consists of two trains each of which has its own multi-media and microfiltration pre-treatment systems prior to desalination. Apart from special membranes, plant design and engineering takes into account the remote location with built in additional redundancy of major systems.

Water for sand mining in remote Eucla Basin

Iluka Resources Jacinth-Ambrosia mineral sands mine currently under development in the Eucla Basin some 200 km north west of Ceduna SA is reputed to be the largest zircon deposit discovered in decades. The only available water comes from highly saline bores - 51,000 mg/L Total Dissolved Solids (TDS) which are located 30km away. Osmoflo was contracted to supply a desalination plant which could provide water of potable grade standard for construction workers and for use in civil works, however the presence of high manganese and iron levels in the feed water, both of which impact negatively on membrane performance, presented a particular challenge. Osmoflo conducted trials with a pilot plant to develop a practical solution before proceeding with a 400kL/d permanent plant which it operates and maintains, The pre-treatment system includes pH adjustment of the feed water from the bores prior to storage in an aeration dam where iron is settled out. The water is then fed through a multimedia filter with special iron removal media before passing through the reverse osmosis membranes. Reject water containing brine is reused in ore slurry processes at the mine.

Recycling mine water for environmental use

Successful underground mining at Xstrata's Ulan Coal Mine, located near Mudgee, NSW requires the extraction of large volumes of water. A reverse osmosis plant and microfiltration pre-treatment system provided by Osmoflo enables the water to be recycled back into the environment along with on-site irrigation. The release of this water in an area that has suffered extensive, prolonged drought is bringing life to streams that have not flowed for many years resulting in the rejuvenation of native flora and fauna and replenishment of fish stocks.

Desalinated reuse water for power generation

Two reverse osmosis plants, with pre-treatment by microfiltration. Both plants utilize the company's proprietry PlantConnect system, providing 24 hour monitoring ensuring optimum plant performance.

Build Own Operate Solution for AGL

Under a Build Own Operate contract Osmoflo has provided AGL's Torrens Island Power Station with a 2ML/d demineralisation plant. Drawing raw water from a local river, the plant provides the high purity water the station requires. The plant is designed for flexible operation that can accommodate the power station's varying demand and source water availability.

Electro-deionisation for Tallawarra Power Station

Alstom Power's gas-fired power station Tallawarra Power Station uses a new fast start 'combined cycles' generation technology which requires high purity water. Osmoflo has designed a technologically advanced 200kL/d two stage reverse osmosis electro-deionisation plant to meet this requirement. A chemical free process provides benefits including much less down time and chemical discharge compared with alternative conventional ion exchange systems.

Wastewater recycling for power plant

A wastewater recycling solution provided by Osmoflo at Origin Energy’s Darling Downs Power Station is enabling the electricity generator to reduce its reliance on bores located some 20km away and is solving a wastewater disposal problem. Prior to the Osmoflo installation, much of the wastewater produced on site needed to be trucked away for disposal, a requirement that is now much reduced. Commissioned in July 2010, the Osmoflo plant includes pre-treatment by multi-media filtration followed by reverse osmosis desalination. Feed water consists of suitable wastewater streams at the site, supplemented by bore water as required. Capacity of the plant is in excess of one megalitre per day (ML/d) with treated water being equivalent to potable standard. To further minimise waste, a microfiltration system treats backwash water enabling its reuse without further treatment. An Osmoflo rental desalination plant was located at the site to deal with immediate water needs prior to the commissioning of the permanent plant.

Treatment of ground water enabling its use in beer production

Water is always a major talking point in Adelaide, capital city of the driest state on the driest continent. Pro-active local industries often lead the way in adopting measures to conserve scarce drinking water supplies. Adelaide's iconic Coopers Brewery is no exception to this cause and when planning its move to a substantially larger site actively sought out water saving measures, including the replacement of mains water with ground water. Osmoflo's solution was to design a plant which could meet growing water useage needs for future expansion. A 3 ML/d reverse osmosis plant was comissioned in March 2007. Coopers are now achieving net savings by using ground water instead of mains water while the use of reject water in irrigation is also reducing effluent discharge costs. This is under a Build Own Operate contract where Osmoflo owns and operates the RO plant and the brewery is billed on consumption.

Unique 'blend control' system for brewery

A unique 'blend control' system provided as part of an Osmoflo reverse osmosis desalination plant at Swan's Canning Vale Brewery in Perth enables automatic adjustment of water quality to meet brew requirements.
