Dairies effluents
Dairies effluents are the wastewaters discharged by dairy plants, carrying milk solids, whey, fats and cleaning chemicals that impose a heavy oxygen demand on receiving waters. Without treatment they can suffocate rivers and produce foul odours. Plants typically screen out solids, strip fats and then use biological reactors where microbes digest the organic load. Regulators enforce discharge standards, and forward-looking dairies recover water, biogas and nutrients, turning an environmental liability into measurable savings. Sampling programs track biochemical oxygen demand and nutrient levels to prove compliance before any release to the environment.
