, BIOFILMS – MUNICIPAL WASTEWATER TREATMENT
• Municipal Wastewater Treatment:

– Municipal Wastewater Treatment: Treatment systems designed to remove
deleterious constituents of interest from water prior to release to natural
waters.

– Conventionally treated constituents: Carbonaceous material, solids,
pathogens and nutrients.

– Conventional treatment systems in Canada:

» Rural: Lagoon (suspended growth)

» Urban: Activated Sludge (suspended growth)
