Key Facts
Tannery in Wiri, Auckland was causing odour problems with neighbours. Gases were extracted from Challenge Cook tanning drums and treated in this crossflow scrubber. Armatec also supplied ducting, fan, stack and chemical dosing equipment. The two stage scrubber was designed to minimise chemical consumption. See paper written.
Formaldehyde Scrubbing at Particle Board Plant
Ammonia Scrubber and Fibreglass Ducting at Wastewater Treatment Plant
Air given off from the biosolids treatment plant at Watercare’s Mangere wastewater treatment plant contains ammonia and odours. This air had to be captured and ducted away for treatment in soil bed filters. However firstly the ammonia had to be removed as it would have had an adverse effect on the soil bed filter biology.
