Industrial wastewater treatment equipment in Richmond

Richmond sits on the Fraser River estuary, where the river's channels braid past Vancouver International Airport and some of Canada's most productive seafood and food processing plants. The city of 210,000 built its industry on that geography: fish processors and cold-storage operators near the river terminals, food manufacturers and aviation-services firms around YVR, all discharging under Metro Vancouver's Bylaw 299 permit system into sewers serving one of the most ecologically sensitive receiving environments in the region.

Processing fish beside an estuary

An estuary is the worst possible place to get seafood effluent wrong: juvenile salmon rear in the same brackish channels that receive the region's treated discharge, and regulators treat the area accordingly. Fish-plant streams here combine high BOD, oils and salt with rapid spoilage that turns a holding-tank problem into an odour complaint overnight. The systems that work pair fine screening and DAF with disciplined housekeeping, prompt offal handling, refrigerated hold tanks where batching is unavoidable. Cold-storage defrost water and aviation de-icing runoff add seasonal streams that need their own routing decisions.
