Food & Beverage Processing in Saint John, New Brunswick

Food and beverage plants produce some of the hardest effluent in Canadian industry. Wash-down water carries fats, oils and grease from fryers and cookers. Blanching and cutting lines add suspended solids. Sugars, starches and proteins push BOD far above what a municipal sewer bylaw allows. A vegetable cannery and a snack-food plant can sit in the same industrial park and send completely different effluent to the same interceptor, which is why food processing wastewater treatment starts with a characterization of your actual discharge, not a catalogue number.

Two directions of regulatory pressure

The regulatory pressure comes from two directions. Municipal sewer-use bylaws in cities like Toronto, Calgary and Montreal set limits on FOG, BOD, TSS and pH, and charge overstrength surcharges when you exceed them. Provincial permits and the federal Fisheries Act apply the moment any effluent reaches a watercourse. For most food processors the surcharge line item is the first thing that gets management's attention: a plant paying tens of thousands of dollars a year in overstrength fees can often recover the cost of a DAF system within a few operating seasons.

A typical treatment train

A typical treatment train for this sector begins with rotary screening to pull out solids and peel fragments, followed by an equalization tank to flatten the swings between production and clean-in-place cycles. Dissolved air flotation with coagulant and flocculant dosing then removes FOG and fine solids. Where a receiving sewer cannot accept the remaining BOD, an MBBR or anaerobic stage polishes the effluent, and the recovered sludge goes to a screw press for dewatering before disposal or land application.

Sized from your flow data

We size each stage from your flow data and a composite sample. Send us your daily volume, your discharge permit or bylaw limits, and a recent lab analysis, and we return a scoped proposal with equipment selections, footprint and budget. Because we supply the equipment rather than operate the plant, the proposal is built around what your effluent needs, whether that is a single screen or a containerized package plant delivered to a plant in rural Ontario or coastal British Columbia. Seasonal packers deserve one extra note: a plant that runs hard for twelve weeks a year should not carry the capital cost of a system sized for year-round flow, and rental or staged equipment often fits that operating pattern better than a permanent build.
