Woodman Point, Western Australia
Clean TeQ Water worked with Worley Parsons in Perth, Australia to install and test a 42 m3/h pilot plant at the Woodman Point Wastewater Treatment Plant (WWTP). The plant’s purpose was to compare ion exchange technology to a combination of multimedia filtration and reverse osmosis in municipal reuse applications. The plant used a two stage CIF® process to remove cations and then anions (including nitrate) from the feedwater, producing product water with very low TDS for industrial applications.
CIF® was chosen as the solution as direct softening can only reduce hardness a limited amount at a high chemical cost, and fixed bed ion exchanged required more expensive chemicals. Testing successfully validated the CIF® technology has the ability to consistently satisfactorily treat secondary treatment wastewater and produce industrial quality water. Furthermore, it has demonstrated its capability of doing so with similar operating cost, lower power requirements and higher recoveries than MF/RO technology.
