Oil Water Separators in Laval, Quebec
Industrial Wastewater Canada sizes and supplies oil water separators for plants in Laval, Quebec. Local demand is driven by pharmaceuticals, food processing, biotech, plastics, discharging under Laval's sewer-use rules toward Rivière des Mille Îles. 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.
Laval's Cité de la Biotech is the reason its wastewater market punches above the weight of a 438,000-resident city. Vaccine manufacturers, pharmaceutical plants and contract research organizations cluster there alongside food processors and plastics plants, all discharging under CMM By-law 2008-47 with the Rivière des Mille Îles as the local receiving water. Biotech effluent plays by batch rules Pharma and biotech streams rarely fail sewer limits on volume; they fail on what a single batch contains. Cité de la Biotech pharma cluster; CMM By-law 2008-47 discharge limits. That is the regulatory backdrop for oil Water Separators in Laval: equipment gets sized against the local limits on the route to Rivière des Mille Îles, not against a national average.

Oil Water Separators on the ground in Laval
In Laval's Cité de la Biotech, industrial wastewater compliance is batch-wise: kill tanks, hold-test-release and pH swings from 2 to 12, documented once for the CMM and once for the GMP auditor. In Laval, the plants asking about oil Water Separators are mostly in pharmaceuticals, food processing, biotech and plastics, and each of those sectors puts a different load on a treatment train. Cité de la Biotech pharma cluster; CMM By-law 2008-47 discharge limits. Direct discharge toward Rivière des Mille Îles instead requires a ministerial authorization under section 22 of Quebec's Environment Quality Act. In a city of Laval'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 Laval tend to be one-of-a-kind rather than repeat configurations, which is exactly the case where sizing from measured effluent data matters most.
FAQ
Frequently Asked Questions
Everything you need to know about our services.
Do you supply oil Water Separators in Laval?
Yes. Industrial Wastewater Canada sizes and supplies oil Water Separators for plants across Laval and the surrounding region. Most local demand comes from pharmaceuticals, food processing, biotech, plastics. Send a quote request with your flow rate and effluent type and a sized proposal follows.
What discharge rules apply to industrial wastewater in Laval?
Cité de la Biotech pharma cluster; CMM By-law 2008-47 discharge limits. Cleaning-in-place cycles swing pH from 2 to 12 within an hour, spent media carries high COD, and certain actives must be deactivated before any drain. The engineering answer is batch-wise: kill tanks, hold-test-release protocols and equalization that flattens the swings before the by-law's sampling point. Plants discharging to the municipal sewer answer to that regime; anything released directly toward Rivière des Mille Îles needs a ministerial authorization under section 22 of Quebec's Environment Quality Act. We size equipment against whichever limit governs your outfall.
How is oil Water Separators sized for a plant in Laval?
From your numbers, not from the city's. We start with measured flow and effluent characterization, then check the result against Laval's local limits. A processor in a city of 438K with pharmaceuticals 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 Laval?
There is no list price; every system is sized and quoted per project. The economics are local, though. Documentation matters double here, once for the CMM inspector and once for GMP auditors who treat the drain as part of the quality system. Food plants on the island still need classic BOD pretreatment, and both worlds fit inside one service territory. Payback in Laval is usually calculated against those surcharge and compliance costs, and the quote spells that comparison out.
