Industrial Wastewater Canada sizes and supplies oil & gas / produced water for plants in Oshawa, Ontario. Local demand is driven by automotive, food processing, fabrication, logistics, discharging under Oshawa's sewer-use rules toward Lake Ontario. Quote requests with flow rate and effluent type get a sized proposal.

Oil and water separate on their own, given time. The entire discipline of oil and gas wastewater treatment exists because nobody in the industry has that time, and because the last few percent of oil refuses to leave without help. Free oil rises and skims easily. Dispersed droplets need coalescing plates or gas flotation. Emulsified oil, stabilized by production chemicals and shear from pumps, needs chemistry to break before any mechanical device can touch it. Knowing which fraction dominates your stream decides the equipment, which is why we ask for an oil-in-water analysis before we quote anything.
The applications span the value chain. Upstream, produced water from Alberta and Saskatchewan wells carries oil, solids and dissolved salts, and is treated for reinjection, disposal, or reuse in waterfloods, where oil carryover fouls injection formations. Midstream terminals and truck washouts generate slop oil and tank bottoms. Downstream, refineries run API separators as the first line, followed by dissolved gas or air flotation ahead of biological treatment. Gas plants add their own stream: amine and glycol wastes that behave nothing like produced water and should never be mixed with it.
Our equipment for this sector includes API oil water separator packages built to the API 421 gravity-separation design method, corrugated and inclined plate coalescing separators for tighter footprints, induced and dissolved gas flotation units, skimmer systems, and coalescing filter vessels for final polishing where discharge or reinjection specs demand single-digit oil concentrations. For remote batteries and early-production facilities the package arrives skid-mounted and winterized.
Alberta Energy Regulator directives, Saskatchewan disposal rules and federal offshore regulations each define oil-in-water limits differently, so we design against your specific approval rather than a generic number.
Send us the analysis, the flow range and the destination of the water, whether that is disposal well, waterflood or surface discharge. The proposal that comes back will name the separation stages, the expected outlet quality at each, and the turndown behaviour, because oilfield flows never stay at design point for long. A practical note on solids: produced sand and fines shorten the life of every separation stage, so where the well history shows sand production we put hydrocyclones or filtration ahead of the separator rather than letting the API vessel become a settling basin.
Oshawa's industrial identity still runs through the GM assembly complex and the parts, fabrication and logistics operations that grew around it. The city of 175,000 discharges through Durham Region's sewer system to Lake Ontario under Sewer Use By-law 55-2011, and the region's industrial-waste staff administer a market where automotive chemistry dominates: machining coolants, oily wash waters, phosphate and paint-line streams. Coolant management is half the battle In an auto-parts plant the wastewater problem often starts as a fluids problem. Durham Region Sewer Use By-law 55-2011; GM-anchored auto supply chain. That is the regulatory backdrop for oil & Gas / Produced Water in Oshawa: equipment gets sized against the local limits on the route to Lake Ontario, not against a national average.

In Oshawa's GM-anchored parts corridor, the industrial wastewater win is usually ultrafiltration of machining coolant, turning a forever tanker-disposal cost into a Durham By-law 55-2011 compliant discharge. In Oshawa, the plants asking about oil & Gas / Produced Water are mostly in automotive, food processing, fabrication and logistics, and each of those sectors puts a different load on a treatment train. Durham Region Sewer Use By-law 55-2011; GM-anchored auto supply chain. Direct discharge toward Lake Ontario instead requires an Environmental Compliance Approval from Ontario's Ministry of the Environment, Conservation and Parks. In a city of Oshawa's size the industrial dischargers are few enough that the utility knows each one by name, which cuts both ways at permit renewal. Projects in Oshawa 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 & Gas / Produced Water for plants across Oshawa and the surrounding region. Most local demand comes from automotive, food processing, fabrication, logistics. Send a quote request with your flow rate and effluent type and a sized proposal follows.
Durham Region Sewer Use By-law 55-2011; GM-anchored auto supply chain. Spent machining coolant is a stable oil-in-water emulsion that resists gravity separation entirely; sent untreated to sewer it fails the by-law, and hauled away by tanker it costs by the litre forever. Ultrafiltration changes that arithmetic, splitting the emulsion into a small concentrate for disposal and a permeate the sewer will take, and typically recovering its capital within a couple of years at moderate volumes. 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 Oshawa's local limits. A processor in a city of 175K with automotive 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. Around the automotive core, Oshawa's food processors and fabricators bring conventional BOD and metals work, and Durham's surcharge framework gives every plant a number to beat. Payback in Oshawa 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.
