Industrial Wastewater Canada sizes and supplies dissolved air flotation (daf) systems for plants in Lethbridge, Alberta. Local demand is driven by food processing, agri-food, irrigation agriculture, breweries, discharging under Lethbridge's sewer-use rules toward Oldman 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.
Lethbridge is the food-processing capital of southern Alberta. Potato plants, pork processing, canola crushing and a brewing tradition dating to 1901 cluster in and around this city of 98,000, fed by the largest irrigation district network in Canada and discharging toward the Oldman River. The concentration of high-strength food effluent relative to city size is among the highest in the country. Southern Alberta food-processing capital (potato, pork, canola). That is the regulatory backdrop for dissolved Air Flotation (DAF) Systems in Lethbridge: equipment gets sized against the local limits on the route to Oldman River, not against a national average.

Lethbridge packs potato, pork and canola effluent above 5,000 mg/L BOD into a small-city sewer system, giving it Canada's clearest per-plant economics for food wastewater pretreatment. In Lethbridge, the plants asking about dissolved Air Flotation (DAF) Systems are mostly in food processing, agri-food, irrigation agriculture and breweries, and each of those sectors puts a different load on a treatment train. Southern Alberta food-processing capital (potato, pork, canola). Direct discharge toward Oldman River instead requires an approval under Alberta's Environmental Protection and Enhancement Act. Lethbridge's municipal plant has limited spare capacity, so a single overloaded industrial connection shows up quickly in its intake numbers. Projects in Lethbridge 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 Lethbridge and the surrounding region. Most local demand comes from food processing, agri-food, irrigation agriculture, breweries. Send a quote request with your flow rate and effluent type and a sized proposal follows.
Southern Alberta food-processing capital (potato, pork, canola). A small city carrying big organic loads Potato processing alone can generate effluent above 5,000 mg/L BOD loaded with starch and solids; pork processing adds blood and fat; canola crushing contributes oily washwater. Lethbridge's municipal system has grown up handling this mix, and its surcharge framework gives every processor a clear economic case for pretreatment. Plants discharging to the municipal sewer answer to that regime; anything released directly toward Oldman River needs an approval under Alberta's Environmental Protection and Enhancement 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 Lethbridge's local limits. A processor in a city of 98K 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. The technical playbook is mature, screening, DAF, starch recovery where the solids have feed value, with anaerobic treatment increasingly attractive at the largest sites. Water in an irrigation economy is never free, so reuse of treated process water carries real value here, and the prairie winter adds its standard demand: everything must run through −30 °C cold snaps without drama. Payback in Lethbridge 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.
