ASTM D5120-90-Reapproved2004<\/h3>\n

Historical Standard: Standard Test Method for Inhibition of Respiration in Microbial Cultures in the Activated Sludge Process<\/h4>\n
\n

ASTM D5120<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers a batch procedure that evaluates the impact of selected wastewaters, materials, or specific compounds on the respiration rate of an aqueous microbial culture, such as activated sludge.<\/p>\n

1.2 Alternative procedures for measurement of microbial activity, such as adenosine 5` triphosphate (ATP), specific substrate utilization, etc. are not within the scope of this test method.<\/p>\n

1.3 The results obtained are based on comparisons in a specific test series that examines a range of concentrations of the potentially inhibitory test candidate using batch methods in a laboratory. Results are completed in a short time frame (a few hours).<\/p>\n

1.4 The test results are specific to the microbial culture used. Microbial culture from different wastewater treatment plants will differ in kinds and numbers of organisms, and performance capability. Thus, there is no basis for comparing results for microbial cultures from different treatment facilities.<\/p>\n

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/i><\/p>\n
