Pretreatment definition

Pretreatment means the reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to or in lieu of discharging or otherwise introducing such pollutants into a POTW.
Pretreatment means the reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to or in lieu of discharging or otherwise introducing such pollutants into a POTW. The reduction or alteration may be obtained by physical, chemical, or biological processes, by process changes, or by other means, except as prohibited in 40 CFR 403.6(d).
Pretreatment means the reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to or in lieu of discharging or otherwise introducing such pollutants into a publicly owned treatment works. The reduction or alteration may be obtained by physical, chemical, or biological processes, process changes or by other means, except as prohibited by 40 CFR 403.6(d). Appropriate pretreatment technology includes control equipment, such as equalization tanks or facilities, for protection against surges or slug loadings that might interfere with or otherwise be incompatible with the publicly owned treatment works. However, where wastewater from a regulated process is mixed in an equalization facility with unregulated wastewater or with wastewater from another regulated process, the effluent from the equalization facility must meet an adjusted pretreatment limit calculated in accordance with 40 CFR 403.6(e).

More Definitions of Pretreatment

Pretreatment means the reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to, or in lieu of, introducing such pollutants into the POTW. This reduction or alteration can be obtained by physical, chemical, or biological processes; by process changes; or by other means, except by diluting the concentration of the pollutants unless allowed by an applicable pretreatment standard.
Pretreatment means the treatment of wastewaters from sources before introduction into the wastewater treatment works.
Pretreatment means application of physical, chemical and/or biological processes to reduce the amount of pollutants in or to alter the nature of the pollutant properties in Wastewater prior to discharging such Wastewater into the Wastewater Treatment System.
Pretreatment means the reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to or in lieu of discharging, or otherwise introducing such pollutants into a POTW. The reduction or alteration may be obtained by physical, chemical, or biological treatment processes, by BMPs, by pollution prevention alternatives including process changes, material substitutions, improved operating practices and recycling, or by other means, except as prohibited by paragraph (F) of rule 3745-36-09 of the Administrative Code.
Pretreatment means the reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater before or instead of discharging or otherwise introducing such pollutants into the POTW. The reduction or alteration may be obtained by physical, chemical, or biological processes; process changes; or other means, except for the use of dilution (unless expressly authorized by any applicable pretreatment standard or requirement and the POTW Manager). Appropriate pretreatment technology includes control equipment, such as equalization tanks or facilities, for protection against surges or slug loadings, subject to applicable requirements of local, state and federal laws and regulations.
Pretreatment means a process that preconditions wastewater to neutralize or remove toxic, priority, or non- conventional pollutants that could ad- versely affect sewers or inhibit a pre- liminary, primary, secondary, ad- vanced, or tertiary treatment oper- ation.
Pretreatment means the reduction of the amount of pollutants, the elimination of
