Oil Water Separators in Toronto, Ontario
Industrial Wastewater Canada sizes and supplies oil water separators for plants in Toronto, Ontario. Local demand is driven by food & beverage processing, pharmaceuticals, chemicals, metal finishing, discharging under Toronto'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.
Two designs, one choice
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.
Above-grade, below-grade and API 421
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 from your real flows
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.
Toronto's nearly three million residents share their sewers with the largest concentration of industrial dischargers in Canada: food and beverage plants, pharmaceutical manufacturers, chemical processors and metal finishers, most of them draining to treatment plants that release into Lake Ontario. The city polices what enters those sewers through By-law 681-2010, which caps BOD, TSS and a long list of metals, and bills overstrength discharge by the kilogram. Surcharge math on a Toronto sewer bill For a mid-size food plant, the difference between raw effluent at 3,000 mg/L BOD and pretreated effluent under the 300 mg/L by-law threshold routinely amounts to six figures a year in surcharge fees. Largest industrial base in Canada; City of Toronto Sewers By-law 681-2010 sets strict surcharge limits on BOD, TSS and metals. That is the regulatory backdrop for oil Water Separators in Toronto: equipment gets sized against the local limits on the route to Lake Ontario, not against a national average.

Effluent characterization matched to Toronto's dominant dischargers: food & beverage processing, pharmaceuticals, chemicals, metal finishing
Discharge route review for systems releasing toward Lake Ontario
Oil Water Separators on the ground in Toronto
Toronto's By-law 681-2010 bills overstrength sewer discharge by the kilogram, so a DAF or MBR pretreatment system typically pays for itself faster here than in any other Canadian city. In Toronto, the plants asking about oil Water Separators are mostly in food & beverage processing, pharmaceuticals, chemicals and metal finishing, and each of those sectors puts a different load on a treatment train. Largest industrial base in Canada; City of Toronto Sewers By-law 681-2010 sets strict surcharge limits on BOD, TSS and metals. Direct discharge toward Lake Ontario instead requires an Environmental Compliance Approval from Ontario's Ministry of the Environment, Conservation and Parks. A metro of Toronto's size runs enough industrial flow that the municipal plant polices its intake closely, and surcharge invoices arrive on schedule. We quote oil Water Separators in Toronto often, and the sizing conversation usually starts from a surcharge bill or a compliance letter rather than from a catalogue.
FAQ
Frequently Asked Questions
Everything you need to know about our services.
Do you supply oil Water Separators in Toronto?
Yes. Industrial Wastewater Canada sizes and supplies oil Water Separators for plants across Toronto and the surrounding region. Most local demand comes from food & beverage processing, pharmaceuticals, chemicals, metal finishing. Send a quote request with your flow rate and effluent type and a sized proposal follows.
What discharge rules apply to industrial wastewater in Toronto?
Largest industrial base in Canada; City of Toronto Sewers By-law 681-2010 sets strict surcharge limits on BOD, TSS and metals. Metal finishers face a harder edge: exceed the metals limits and the city can refuse the discharge outright rather than bill for it. A DAF unit, a pH correction stage or a compact MBR sized for a single plant usually pays for itself faster in Toronto than anywhere else in the country, simply because the enforcement is older and more systematic here. 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.
How is oil Water Separators sized for a plant in Toronto?
From your numbers, not from the city's. We start with measured flow and effluent characterization, then check the result against Toronto's local limits. A processor in a city of 2,794K with food & beverage processing as the dominant sector rarely has the same loading profile as its neighbours, so treatability data drives the selection.
What does oil Water Separators cost in Toronto?
There is no list price; every system is sized and quoted per project. The economics are local, though. Payback in Toronto is usually calculated against those surcharge and compliance costs, and the quote spells that comparison out.
