Industrial Wastewater Canada sizes and supplies dissolved air flotation (daf) systems for plants in Montreal, Quebec. Local demand is driven by aerospace, food & beverage, pharmaceuticals, petrochemicals, discharging under Montreal's sewer-use rules toward St. Lawrence River. Quote requests with flow rate and effluent type get a sized proposal.

Dissolved air flotation earns its keep in one specific situation: wastewater loaded with fats, oils, grease and suspended solids that settle poorly or not at all. That is the daily reality of food and beverage plants, dairies, meat and poultry processors and rendering operations, which is why the DAF has become the default pre-treatment technology in those sectors across Canada.
The process is the inverse of settling. A portion of clarified effluent is saturated with air under pressure and released at the tank inlet, where it forms clouds of microbubbles. The bubbles attach to solids and grease particles, float them to the surface as a stable sludge blanket, and a skimmer removes the blanket continuously. With the integrated chemical dosing and flocculation tube on our units, coagulant and polymer conditioning happens in-line ahead of the flotation zone, and removal rates run from 90 to 99 percent on TSS and FOG when the chemistry is tuned to the stream.
The economics are usually driven by surcharges rather than fines. A plant discharging over-strength effluent to a Canadian municipality pays for it, either through an industrial waste surcharge agreement in much of Ontario or through permit conditions like Metro Vancouver's Bylaw 299. Those fees scale with production and never stop. A DAF is a one-time capital cost that cuts the surcharged load at the source, and we size every unit with that payback math in view, using your actual surcharge invoice where you have one. For many food processors the system pays for itself against fees alone.
Construction is stainless steel, and the compact skid packages arrive pre-piped and pre-wired, which keeps installation to utility connections and commissioning rather than a fabrication project on your floor. A DAF also protects whatever sits downstream: a biological system runs far more stably when the grease load is removed ahead of it, and a municipality sees a plant that holds its numbers.
Sizing a DAF from a brochure is guesswork. Sizing it from data takes three inputs: your peak flow rate, a lab analysis of the effluent or at minimum a description of the process producing it, and your discharge limits. Send those and we return a sized configuration, budget price and delivery timeline for your plant, anywhere in Canada, with every proposal reviewed by a process engineer first. Commissioning includes jar testing on site to lock in the coagulant and polymer recipe, and operator training is part of the startup scope, because a DAF tuned once and understood by the people running it holds its removal rates for years.
An industrial discharger in Montreal answers to two regulators at once. The metropolitan community's By-law 2008-47 governs what the city's sewers will accept, while Quebec's environment ministry (MELCCFP) issues the industrial attestations that direct dischargers to the St. Lawrence must hold. Quebec MELCCFP industrial discharge attestations; CMM By-law 2008-47 governs sewer discharge across the metro. That is the regulatory backdrop for dissolved Air Flotation (DAF) Systems in Montreal: equipment gets sized against the local limits on the route to St. Lawrence River, not against a national average.

Montreal industrial wastewater lives under a double layer of regulation, CMM By-law 2008-47 for the sewer and MELCCFP attestations for the St. Lawrence, and every compliance file has to stand up in French. In Montreal, the plants asking about dissolved Air Flotation (DAF) Systems are mostly in aerospace, food & beverage, pharmaceuticals and petrochemicals, and each of those sectors puts a different load on a treatment train. Quebec MELCCFP industrial discharge attestations; CMM By-law 2008-47 governs sewer discharge across the metro. Direct discharge toward St. Lawrence River instead requires a ministerial authorization under section 22 of Quebec's Environment Quality Act. A metro of Montreal's size runs enough industrial flow that the municipal plant polices its intake closely, and surcharge invoices arrive on schedule. We quote dissolved Air Flotation (DAF) Systems in Montreal often, and the sizing conversation usually starts from a surcharge bill or a compliance letter rather than from a catalogue.
Everything you need to know about our services.
Yes. Industrial Wastewater Canada sizes and supplies dissolved Air Flotation (DAF) Systems for plants across Montreal and the surrounding region. Most local demand comes from aerospace, food & beverage, pharmaceuticals, petrochemicals. Send a quote request with your flow rate and effluent type and a sized proposal follows.
Quebec MELCCFP industrial discharge attestations; CMM By-law 2008-47 governs sewer discharge across the metro. Aerospace surface-treatment shops, food and beverage plants, pharmaceutical manufacturers and the east-end petrochemical corridor all navigate this double layer. Two regulators, one discharge point The practical consequence is paperwork with teeth: a pretreatment system here has to be documented in French, matched to the attestation's specific parameter list, and able to prove itself with composite sampling rather than grab samples. 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 Montreal's local limits. A processor in a city of 1,763K with aerospace 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. Aerospace platers worry about chromium and cyanide limits measured in the hundreds of micrograms per litre; a brewery worries about BOD surcharges instead. We build the treatment train around the specific attestation or by-law schedule a plant holds, then set up the sampling and reporting so the compliance file writes itself. Payback in Montreal 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.
