Meeting the Water Treatment Needs of a Remote Mining Site in Western Australia
Sino Iron is one of the world’s largest iron ore mining projects, located at Cape Preston, in the Pilbara region of Western Australia (approx 1,500 km north on Perth). The mine is being developed by one of China’s biggest steel producers, in order to meet the growing needs of the global steel industry.
The project includes construction of a dedicated gas-fired combined-cycle 450MW power station (being constructed by Austrian Energy & Environment) and will be supplied with water from a large regional seawater desalination plant (constructed by IDE Technologies).
Nirosoft Industries Ltd. has been awarded the order for the design, manufacture, supply, construction and commissioning of a Water Treatment Plant for the new power station, which will supply its various water requirements.
The system will be fed by desalinated seawater from the IDE plant, and further treat the water to meet the stringent quality requirements of the power station, using the following processes & equipment:
Ø First-pass RO membranes for supply of permeate for cooling & other uses.
Capacity: 1000 m3/day.
Ø Second-pass RO + EDI demineralization for supply of Ultra-Pure water for high-pressure steam boilers.
Capacity: 450 m3/day.
Ø Conditioning of RO permeate for potable use according to Australian Standards, including remineralisation by calcite filters & disinfection.
Capacity: 120 m3/day.
All the systems are supplied as containerized units, and will operate fully automatically, with 100% duty/ stand-by redundancy and remote monitoring & control.
The complete containerized units are designed, built & tested by Nirosoft according to strict client requirements, and delivered to site for installation & commissioning.
In addition, the scope of supply for the project includes large water tanks, full assembly and project management.
The system is scheduled to be operative by April 2009.
