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.
