Industrial Wastewater Canada sizes and supplies oil & gas / produced water for plants in Trois-Rivieres, Quebec. Local demand is driven by pulp & paper, aluminum, food processing, port industry, discharging under Trois-Rivieres's sewer-use rules toward St. Lawrence River. 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.
Trois-Rivières sits midway between Montreal and Quebec City, where the Rivière Saint-Maurice meets the St. Lawrence, and its industry has always used that water: pulp and paper mills that once made it the newsprint capital of the world, an aluminum smelter, food processors and an active port. The city of 139,000 discharges under Quebec's MELCCFP attestation regime, with the St. Paper and aluminum corridor midway Montreal–Quebec City. That is the regulatory backdrop for oil & Gas / Produced Water in Trois-Rivieres: equipment gets sized against the local limits on the route to St. Lawrence River, not against a national average.

Trois-Rivières' surviving paper mills keep converting to specialty products, and every furnish change hands their decades-old wastewater treatment a chemistry it was never designed for. In Trois-Rivieres, the plants asking about oil & Gas / Produced Water are mostly in pulp & paper, aluminum, food processing and port industry, and each of those sectors puts a different load on a treatment train. Paper and aluminum corridor midway Montreal–Quebec City. Direct discharge toward St. Lawrence River instead requires a ministerial authorization under section 22 of Quebec's Environment Quality Act. Trois-Rivieres's municipal plant has limited spare capacity, so a single overloaded industrial connection shows up quickly in its intake numbers. Projects in Trois-Rivieres 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 Trois-Rivieres and the surrounding region. Most local demand comes from pulp & paper, aluminum, food processing, port industry. Send a quote request with your flow rate and effluent type and a sized proposal follows.
Paper and aluminum corridor midway Montreal–Quebec City. Lawrence as receiving water. An industrial river town reinventing its mills The newsprint era is over, and the surviving mills have diversified into specialty papers, packaging and bioproducts, each conversion changing the effluent as much as the product. Plants discharging to the municipal sewer answer to that regime; anything released directly toward St. Lawrence River needs a ministerial authorization under section 22 of Quebec's Environment Quality Act. 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 Trois-Rivieres's local limits. A processor in a city of 139K with pulp & paper 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. A mill that switches furnish or adds a coating line inherits new wastewater chemistry that its decades-old treatment was never designed for, and updating the attestation is part of every such project. Aluminum and food processing add fluoride-bearing and organic streams respectively. The regional workforce carries generations of process-industry skill, and projects here move on practical trust: references, site visits and French-language documentation count for more than glossy proposals. Payback in Trois-Rivieres 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.
