Blowdown water is also know as “boiler blowdown.” Boiler blowdown is water that is released from a boiler to remove impurities and sediment. Periodically rinsing out the boilers helps limit the buildup of contaminants in the boiler water that may degrade boiler performance. Blowdown water is an industrial wastewater and usually contains contaminants such as dissolved/suspended minerals, heavy metals (iron, copper), corrosion inhibitors, oil, and/or algaecides.
