Industrial Wastewater Canada sizes and supplies oil water separators for plants in Mississauga, Ontario. Local demand is driven by pharmaceuticals, food & beverage, chemicals, logistics, discharging under Mississauga's sewer-use rules toward Lake Ontario. Quote requests with flow rate and effluent type get a sized proposal.

Every vehicle wash bay, machine shop, fuel depot and refinery in Canada faces the same line item in its sewer-use bylaw: oil and grease, typically capped somewhere between 15 and 100 mg/L depending on the municipality. An oil water separator is the standard way to meet that cap. It exploits the density difference between oil and water: flow slows inside the vessel, droplets rise and coalesce into a surface layer that gets skimmed, and cleaned water leaves from below.
The choice that matters is between the two main designs. A gravity API separator is a long rectangular basin sized to Stokes' law, built to let droplets of roughly 150 microns and larger rise out. It is robust, tolerant of solids and easy to maintain, which is why refineries still standardize on it. A coalescing-plate separator adds inclined plate packs or oleophilic media that intercept far smaller droplets, down to about 20 to 60 microns, so it reaches better effluent quality in a fraction of the footprint. Our coalescing configurations hold effluent under 10 ppm oil and grease in free-oil service, and many sites pair an API basin with a coalescing polishing stage.
We quote both, in above-grade and below-grade tanks, with API 421 compliant configurations where the specification calls for it. Options include oil-stop valves that close automatically when the oil layer reaches capacity, high-level alarms, and sludge baffles for streams that carry grit. What a separator will not do is remove chemically emulsified or dissolved oil; if your stream carries surfactants from a wash process, we will tell you plainly that you need chemical treatment or flotation ahead of the separator, because selling you a tank that cannot meet your limit helps neither of us.
Sizing depends on flow rate, droplet size distribution and oil type, which is why the search term oil water separator, at 480 searches a month in Canada, so often ends in a mis-sized purchase from a catalogue. Send us your flow, a recent lab analysis or a description of the process, and your discharge destination. We return a sized configuration, budget price and delivery timeline, reviewed by a process engineer before it reaches you, for any site in Canada. Installation support and commissioning are quoted per project, and replacement plate packs and media remain available for the life of the vessel. Below-grade installations ship with traffic-rated covers where the separator sits in a drive lane, and we keep skimmer parts and alarm components on the shelf so a maintenance call does not become a compliance gap.
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. Peel Region Sewer Use By-law 53-2010; dense pharma and food plant corridor along the 401. That is the regulatory backdrop for oil Water Separators in Mississauga: equipment gets sized against the local limits on the route to Lake Ontario, not against a national average.

On Mississauga's 401 corridor, pharma plants and food processors fail Peel's Sewer Use By-law 53-2010 in opposite ways, and tight lots mean the winning wastewater system is the one that fits inside a loading bay. In Mississauga, the plants asking about oil Water Separators are mostly in pharmaceuticals, food & beverage, chemicals and logistics, and each of those sectors puts a different load on a treatment train. Peel Region Sewer Use By-law 53-2010; dense pharma and food plant corridor along the 401. Direct discharge toward Lake Ontario instead requires an Environmental Compliance Approval from Ontario's Ministry of the Environment, Conservation and Parks. Mississauga is big enough that the sewer utility samples industrial connections routinely, so an out-of-spec effluent gets noticed within a billing cycle. Projects in Mississauga tend to be one-of-a-kind rather than repeat configurations, which is exactly the case where sizing from measured effluent data matters most.
Everything you need to know about our services.
Yes. Industrial Wastewater Canada sizes and supplies oil Water Separators for plants across Mississauga and the surrounding region. Most local demand comes from pharmaceuticals, food & beverage, chemicals, logistics. Send a quote request with your flow rate and effluent type and a sized proposal follows.
Peel Region Sewer Use By-law 53-2010; dense pharma and food plant corridor along the 401. 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. Plants discharging to the municipal sewer answer to that regime; anything released directly toward Lake Ontario needs an Environmental Compliance Approval from Ontario's Ministry of the Environment, Conservation and Parks. We size equipment against whichever limit governs your outfall.
From your numbers, not from the city's. We start with measured flow and effluent characterization, then check the result against Mississauga's local limits. A processor in a city of 718K with pharmaceuticals as the dominant sector rarely has the same loading profile as its neighbours, so treatability data drives the selection.
There is no list price; every system is sized and quoted per project. The economics are local, though. 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. Payback in Mississauga is usually calculated against those surcharge and compliance costs, and the quote spells that comparison out.
Flow, contaminants, discharge limit. An engineer replies with a sized treatment train and a quote — no obligation.
