Challenge Mt Piper Power Station relies on an evaporative cooling system through twin hyperbolic cooling towers to provide the necessary cooling capacity for steam condensate. Water is drawn from a local river and repositories to replace the amount lost through the cooling process. The challenge was to pre-concentrate the draw-down water prior to treatment by the brine concentrators.

Solution Osmoflo's solution involved pre-treatment through a 200 micron strainer to remove most particulate and fibrous matter and then hollow fibre microfiltration prior to Reverse Osmosis (RO) desalination. Operating at 75% recovery, the RO system reduces the salinity of feed water from upto 3,600mg/L Total Dissolved Salts (TDS) to less than 50mg/L. The process is continuously monitored by Osmoflo's patented PlantConnect remote control and monitoring system, ensuring optimum plant performance and eliminating the need for full time operators on site.

Result Water intake from local sources has been reduced while the need to discharge saline water is zero.
