Industrial wastewater treatment equipment in Windsor

Windsor's wastewater market is really two markets an hour apart. In the city of 230,000, auto assembly and parts plants generate oily emulsions, phosphate rinses and paint-shop effluent governed by Sewer Use By-law 168-2005, discharging toward the Detroit River. Down the highway in the Leamington-Kingsville greenhouse belt, North America's densest concentration of vegetable greenhouses produces nutrient-rich process water and irrigation leachate with entirely different rules and receiving waters.

Paint shops and greenhouse leachate

Automotive effluent is a mature discipline: ultrafiltration for oily emulsions, chemical treatment for phosphating lines, careful handling of paint-detackification water. The greenhouse side is younger and moving fast, with provincial scrutiny of nutrient discharges to Lake Erie tributaries pushing growers toward recirculation, denitrification and phosphorus capture. Feedwater at a greenhouse might carry 200 mg/L nitrate where a receiving stream target is a fraction of that. Windsor-area suppliers who can serve a transmission plant on Tuesday and a tomato operation on Wednesday match how this region actually works.
