Breweries & Distilleries in Burnaby, British Columbia

Brewery effluent looks harmless and behaves badly. Most of what goes down the drain is water, but the fraction that is not includes spent grain fines, yeast, trub, spilled wort and packaging-line beer, all of which are concentrated food for bacteria. That is why brewery wastewater treatment matters even for a craft operation producing a few thousand hectolitres a year: BOD in raw brewery discharge routinely runs ten to thirty times the strength of domestic sewage, and municipal sewer bylaws price that difference directly.

The pH problem

The second problem is pH. Caustic keg and tank washing pushes discharge alkaline, acid sanitizers push it the other way, and the swings arrive in slugs when a cleaning cycle finishes. Many breweries fail their sewer agreement on pH alone before BOD ever becomes the issue. A small equalization tank with automated pH correction is often the cheapest compliance step a brewery can take, and it is where we usually start.

The train depends on scale

Beyond equalization, the treatment train depends on scale. A regional craft brewery discharging to a tolerant municipal sewer may only need solids screening, pH control and side-streaming of high-strength waste like trub and yeast, which can go to farmers or anaerobic digestion instead of the drain. A production brewery, or one on a small-town sewer system, typically adds dissolved air flotation to strip solids and then biological treatment. Anaerobic wastewater treatment suits the strongest streams because it produces biogas rather than consuming aeration power, while an MBBR handles the polishing stage in a footprint that fits a utility room.

Water on the intake side

Water is also a cost on the intake side. Breweries that treat well enough can reuse effluent for floor wash and cooling, cutting both the water bill and the discharge volume the surcharge is calculated on.

What we need from you

Tell us your annual production, your cleaning chemistry and your sewer agreement limits, and we will size the tanks and equipment to match. For breweries in growth mode we design the first stage so the biological stage can bolt on later without rework. Distilleries follow the same logic with two differences worth naming: stillage is far stronger than any brewery stream and usually justifies dedicated handling, and copper carryover from the stills can matter to a sewer agreement even at low concentrations.
