REMOVING PHOSPHORUS TO CONCENTRATIONS BELOW 0.03 mg/l

Clean Water Technology Ltd has developed a novel competitive technology - CWTMedia technology - for the removal of phosphorus (P) from wastewater discharges to concentrations below 0.03 mg P/l, which is the commonly accepted concentration at about which eutrophication can occur. The technology is based on a special synthetic filter media and does not involve the use of iron salts e.g., ferrous sulphate, etc.

The CWTMedia technology was installed in 2007 at a Wexford County Council wastewater treatment plant where tests have been carried out since. A summary of the independent Technology Validation Report that resulted from an intensive testing programme carried out in November 2009 on the CWTMedia technology at the County Wexford plant by Dr. Michael Rodgers, Edmond O’Reilly MEngSc and Salvadore McNamara BE from Civil Engineering, NUI Galway, can be viewed on our services page.

Clean Water Technology Ltd is fully confident that this competitive CWTMedia technology can enable wastewater treatment plant operators meet the most stringent requirements of EPA licenses in relation to phosphorus removal. Further, the limited solid residuals resulting from the innovative technology can be used locally as a fertiliser.
