Industrial Wastewater
Industrial wastewater refers to water that has been used from industries and is refused. Industrial wastewater is either biodegradable and can be treated or reused similar to blackwater or greywater; or it contains pollutant that are not biodegradable and require an advanced oxidation process for treatment. Often, industrial wastewater also just contains heat, which can be reused for energy generation or other processes (e.g. aquaculture).
