Withstanding aggressive applications
Published: 28 November 2012 - Michelle Lea
Problem: The expansion of a wastewater treatment plant on the Persian Gulf meant there was a need for mixers that could withstand the aggressive nature of the application.
Solution: The near 100,000m3/day plant (post-expansion) will utilise 11 GT Chemineer mixers that have been specially coated in Derakane. This corrosion-resistant epoxy vinyl ester resin withstands the application which sees wastewater first acidified, alkalised and then dosed with hydrogen peroxide to remove all organic compounds.
The GT mixers were selected for their proven reliability in tough activated sludge and tertiary treatment processes where international environmental standards for disposal and reuse have to be met.
