BACKGROUND
SOLUTION
The treatment consisted of a metal precipitation process, followed by a clarification process. BOD5 was removed using an aerobic biological reactor, while ammonia nitrogen was oxydized into nitrate in a nitrification biological reactor. TSS were removed using sand and bag filtrations units. Finally, dissolved and colloidal hydrophobic molecules were removed using ULTRASORPTION™ and activated carbon filtrationé
Analyses of water samples, as well as toxicity testing, were performed regularly to monitor the treatment efficiency and to ensure compliance with the discharge objectives. The discharge was supervised by officials from the City of Iqaluit, the Nunavut Water Board, and Environment and Climate Change Canada.
QE has successfully treated more than 13,000,000 L of heavily contaminated water, which was discharged into Koojesse Inlet.
In addition to having successfully treated heavily contaminated water on Baffin Island (Nunavut), QE also contributed to the local economy by favouring the hire of local labourers and contractors.
Furthermore, the quality and implementation of the health and safety program ensured that the work was completed without incident.
