Industrial Wastewater Canada sizes and supplies dissolved air flotation (daf) systems for plants in Quebec City, Quebec. Local demand is driven by food processing, pulp & paper, defence, electronics, discharging under Quebec City'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.
Quebec City's industrial base is easy to underestimate from outside: food processors in the Saint-Roch and Lebourgneuf parks, a pulp and paper legacy, defence electronics and a growing optics-photonics cluster, all inside a provincial capital of 549,000 people on the St. Lawrence. What sets the market apart is procurement culture. Provincial capital; MELCCFP oversight, strong FR-language procurement requirement. That is the regulatory backdrop for dissolved Air Flotation (DAF) Systems in Quebec City: equipment gets sized against the local limits on the route to St. Lawrence River, not against a national average.

Quebec City is the MELCCFP's home town, and industrial wastewater projects here move at the speed of your French-language engineering file. In Quebec City, the plants asking about dissolved Air Flotation (DAF) Systems are mostly in food processing, pulp & paper, defence and electronics, and each of those sectors puts a different load on a treatment train. Provincial capital; MELCCFP oversight, strong FR-language procurement requirement. Direct discharge toward St. Lawrence River instead requires a ministerial authorization under section 22 of Quebec's Environment Quality Act. Quebec City is big enough that the sewer utility samples industrial connections routinely, so an out-of-spec effluent gets noticed within a billing cycle. Most Quebec City projects reach us after a sampling result or a bylaw notice, so the first step is matching equipment to the parameter that triggered it.
Everything you need to know about our services.
Yes. Industrial Wastewater Canada sizes and supplies dissolved Air Flotation (DAF) Systems for plants across Quebec City and the surrounding region. Most local demand comes from food processing, pulp & paper, defence, electronics. Send a quote request with your flow rate and effluent type and a sized proposal follows.
Provincial capital; MELCCFP oversight, strong FR-language procurement requirement. This is the seat of the MELCCFP itself, and public and para-public buyers here expect fully French-language engineering deliverables, from P&IDs to operator manuals. Selling treatment systems in the regulator's home town A pretreatment project in Quebec City moves faster when the attestation file, the commissioning report and the operator training all arrive in French the first time, because reviewers here read them closely. 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 Quebec City's local limits. A processor in a city of 549K with food processing 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. Technically the work is familiar: high-strength food effluent in the 2,000 to 5,000 mg/L BOD range, paper-machine whitewater, and institutional labs. Commercially, the differentiator is a supplier who can walk into a MELCCFP meeting and carry the conversation without a translator. Payback in Quebec City 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.
