Chemineer’s mixers get their coats on for Saudi desal

Posted: Friday 18th January 2013

Specially-coated mixers from Chemineer are set to play a key role in the major expansion of a wastewater treatment plant on the Persian Gulf.

The near 100,000m3/day plant (post-expansion) will utilise 11 GT Chemineer mixers that have been coated in Derakane. This corrosion-resistant epoxy vinyl ester resin withstands the aggressive nature of the application which sees wastewater first acidified, alkalised and then dosed with hydrogen peroxide to remove all organic compounds

Featuring a new, high-efficiency gearbox designed specifically for agitator service, Chemineer’s GT mixers were selected for their proven reliability in tough activated sludge and tertiary treatment processes where the highest international environmental standards for disposal and reuse have to be met.

Made for ultra-reliable performance and long lifespan due to cast gearboxes with heavy duty output shaft and bearings, the GT mixers from Chemineer include a fully comprehensive Derakane coating for the shafts of the agitators, which were wrapped with a glass fibre blanket, then sealed with the high quality resin. The choice of material also allowed for any potential damage during transit or installation as Derakane is readily fill-patchable.
