2 Scope
2.1 This standard covers reference standards, definitions, general requirements, testing requirements, installation instructions, and marking and identification for nitrogen reducing technology. Technology covered by this standard includes aeration systems designed to initiate the oxidation of ammonia to nitrite or nitrate, anaerobic components designed to denitrify nitrite or nitrate, special bacterial blends to achieve enhanced conversion of nitrite or nitrate to nitrogen gas, either aerobically or anaerobically so that the concentration of total nitrogen in the effluent leaving the tank will be reduced by at least one-half of that of the raw influent introduced into the tank. The technology shall be designed to fit in standard septic tanks, either new or previously installed, such that no structural change to the septic tank shall occur.
