Industrial wastewater treatment equipment in Mississauga

The stretch of Mississauga along Highway 401 holds one of the densest runs of pharmaceutical and food plants in the country. A city of 718,000 built around logistics, it discharges through Peel Region's sewer system to Lake Ontario under Sewer Use By-law 53-2010, and Peel's enforcement staff know their industrial customers well.

Pharma corridor, food corridor, one by-law

The two dominant industries fail the by-law in different ways. Pharmaceutical sites trip limits on solvents, active ingredients and pH excursions from batch cleaning; their fix is usually equalization, neutralization and sometimes carbon polishing on a 20 to 200 m³/day stream. Food and beverage plants fail on BOD and fats, oils and grease, where a properly sized DAF recovers most of the surcharge. Because plants here sit shoulder to shoulder on small lots, footprint drives many decisions: vertical clarifiers, stacked equalization tanks and systems that fit inside an existing loading bay beat sprawling outdoor lagoons every time.
