Armatec designed and installed a >99% efficient biological scrubbing system for the award-winning Pines II Rolleston wastewater treatment plant.
Packed Bed Scrubber
Smaller scrubber for tannery in Dunedin that was required to reduce their odourous hydrogen sulphide emissions to meet Air Discharge Requirements
Fibreglass Hoods & Covers
Armatec supplies all fibreglass lip extraction hoods for Challenge Cook drums. These provide good capture of odourous hydrogen sulphide, without restricting access to the drums for loading and unloading animal hides.
The Tasman District Council had a small WWTP serving a 7500–10500 population which swelled in Summer.

There are two problems faced by all wastewater pump stations: corrosion and odour. Typical concrete pump stations corrode within 20 years of installation, and do not meet the requirement of a 50 year design life required in municipal applications. Corrosion is worse when there are long residence times in the system, as the wastewater can go anaerobic and produce significant quantities of corrosive hydrogen sulphide.
