Sea water de-salination with PROFIBUS (Australia)



The Southern Seawater Desalination Plant (SSDP), located in Binningup, is Western Australia’s second seawater desalination plant. It is owned by the Water Corporation, the main provider of water, wastewater and drainage services in Western Australia. High availability was a key requirement for the Water Corporation, so redundancy throughout the process and mechanical design was a priority when evaluating and planning the SSDP’s network design.


Water Corporation decided to adopt PROFIBUS PA and PROFIBUS DP for all water treatment and desalination plants. While Worley Parsons won the tender to design the Control System, in practice the initial design is usually followed by consultation and design modifications with the System integrators – BlochTech – whose responsibility was to program the design and make it work. The design, construction and operation is the responsibility of the Southern Seawater Alliance (SSWA), comprising Technicas Reunidas, Valoriza Agua, AJ Lucas, WorleyParsons and the Water Corporation. The SSDP is a seawater reverse osmosis based plant. Stage 1 delivers water to over 1.7 million people in Perth. Stage 2 is currently being commissioned.


The Water Corporation’s decision to adopt PROFIBUS for all water treatment and desalination plants is seen as the key to the Water Corporation's big picture vision for the state’s future water supply.
