Industrial Wastewater Canada sizes and supplies dissolved air flotation (daf) systems for plants in Sherbrooke, Quebec. Local demand is driven by machinery, rubber & plastics, food processing, textiles, discharging under Sherbrooke's sewer-use rules toward Rivière Saint-François. 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.
Sherbrooke anchors the Estrie manufacturing economy: machinery builders, rubber and plastics processors, food plants and a surviving textile sector spread through a city of 173,000 on the Rivière Saint-François. Discharges follow Quebec's MELCCFP framework, and the city's own sewer rules govern connections to the municipal plant. What colours the market is the university presence, Université de Sherbrooke's engineering faculty feeds the region a steady supply of talent and a taste for trying newer treatment approaches. Estrie manufacturing base with university-driven cleantech adoption. That is the regulatory backdrop for dissolved Air Flotation (DAF) Systems in Sherbrooke: equipment gets sized against the local limits on the route to Rivière Saint-François, not against a national average.

Sherbrooke's university-fed manufacturing base pilots newer industrial wastewater technologies, electrocoagulation, MBRs, earlier than comparable cities, with the trial often co-supervised from a campus lab. In Sherbrooke, the plants asking about dissolved Air Flotation (DAF) Systems are mostly in machinery, rubber & plastics, food processing and textiles, and each of those sectors puts a different load on a treatment train. Estrie manufacturing base with university-driven cleantech adoption. Direct discharge toward Rivière Saint-François instead requires a ministerial authorization under section 22 of Quebec's Environment Quality Act. In a city of Sherbrooke'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 Sherbrooke 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 dissolved Air Flotation (DAF) Systems for plants across Sherbrooke and the surrounding region. Most local demand comes from machinery, rubber & plastics, food processing, textiles. Send a quote request with your flow rate and effluent type and a sized proposal follows.
Estrie manufacturing base with university-driven cleantech adoption. A mid-size market that adopts early Sherbrooke plants punch above their size in cleantech adoption. A rubber processor here is more likely than its Ontario counterpart to pilot electrocoagulation or a membrane bioreactor, partly because a professor's lab will co-supervise the trial. Plants discharging to the municipal sewer answer to that regime; anything released directly toward Rivière Saint-François 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 Sherbrooke's local limits. A processor in a city of 173K with machinery 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. The industrial streams themselves are varied: latex and additive-laden rinses from rubber lines, oily machinery wastewater, food-plant BOD in the 1,500 to 3,000 mg/L range. All of it lands in a francophone regulatory process where the attestation file, the pilot report and the operator training work best written in French from the start. Payback in Sherbrooke 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.
