Industrial Pretreatment

Domestic wastewater is wastewater originating from activities such as restroom usage, washing, bathing, food preparation, and laundry.
Industrial wastewater is process wastewater originating from manufacturing, commercial businesses, mining, agricultural production and processing, and wastewater from cleanup of petroleum and chemical contaminated sites, to name a few. According to the Florida Department of Environmental Protection Agency (http://www.dep.state.fl.us/Water/wastewater/iw/index.htm), all wastewater that is not defined as domestic wastewater is considered industrial wastewater.
All industrial wastewater that discharges to domestic wastewater or reclamation treatment facility, must be regulated under the Industrial Pretreatment Program.
Local limits are developed to meet the pretreatment program objectives and site-specific needs of the POTW. The local limits are threshold values for a specific set of pollutants and are applicable to all industrial facilities that discharge to a POTW.
