The City of Portage la Prairie is required to meet the Province of Manitoba’s new effluent limits of 1 mg/L total phosphorus and 15 mg/L total nitrogen at their Water Pollution Control Facility (WPCF) and will need an upgrade to achieve this. Industrial flows to the system contribute approximately 90% of the N and P loads. To investigate methods to reduce these loads, piloting of the Ostara Pearl® struvite crystallization and Veolia ANITAMox deammonification systems was performed. The objective of this thesis was to pilot the ANITAMox system for seven months and determine the impact of the following process conditions: reduced influent temperature; increased pH; periodic high influent TSS concentrations; and modifications to the ANITAMox process train comprising of elimination of the pretreatment BOD removal reactor. It was found that deammonification could be an option for reducing mainstream ammonia loading from industrial flows at the WPCF.
