About This Item


Full Description

This Standard is intended for use with devices intended to disinfect wastewater after secondary treatment and prior to discharge from residential wastewater treatment systems having rated treatment capacities between 757 L/d (200 gal/d) and 5,678 L/d (1,500 gal/d). This Standard also applies to devices intended to be used in water reclamation and reuse. Specific requirements exist for construction and testing of individual disinfection devices based on the technology used by the device. All devices are required to be tested against the influent challenge water as specified in Section 1.4 and to meet the minimum effluent quality requirements in accordance with Section 1.5. Devices shall be tested against the effluent requirements of this Standard unless the manufacturer requests certification under an effluent standard in NSF/ANSI 350, which is more stringent than this Standard.
