Walkerton - Conventional and Dissolved Air Flotation Jar Testing Services

n 2018, the Walkerton Clean Water Centre (WCWC) completed a project with a First Nation community in Northern Ontario, which has been on a long-term boil water advisory since 2013. The community retained a consulting engineer to complete a feasibility study to recommend treatment solutions. WCWC tested two treatment solutions that were recommended by consultants; conventional treatment and dissolved air flotation. Jar testing was conducted using the community’s source water and different coagulation chemicals in WCWC’s laboratory. The water quality was monitored and results were provided to the community. The project was beneficial for the consultant in designing the drinking water treatment system expansion.
