Rental Reverse Osmosis Plant

Water Rentals deployed a rental reverse osmosis plant and mixed bed polishers to meet ultra-high purity water quality requirements of a major power station in New South Wales. The application involves treatment of the filtered water to produce water suitable for steam raising in power station’s high-pressure boilers. Additional processing capacity on rental basis was used to complement the existing site ion exchange facilities that required down time for upgrade works.

The 1.5 MLD water treatment facility includes two trains of rental reverse osmosis systems operating in 2-pass mode with associated chemical dosing systems, chemical cleaning systems and auxiliary facilities such as air compressors. Final polishing is carried out using rental non-regenerable mixed bed ion exchange polishers. The plant was mobilised within 2 weeks and commissioned within 2 weeks following completion of installation.

The plant is setup as a composite facility with an advanced common control system that includes Water Rentals’ remote monitoring system. This allows for regular monitoring of plant operations and plant performance reducing site reliance on specialist operators. Remote support and programmed site visits ensure the equipment is maintained pro-actively and that the plant is available when required.

The rental facility continues to provide a reliable source of ultra pure water an has become an important backup system to critical infrastructure.
