  • Application Focus: Biological Wastewater Treatment

    In knowing the size and health of the active biomass population in a wastewater treatment process, cause-and-effect relationships can then be established with process variables. If a change in the process is beneficial or detrimental to the population, ATP results will indicate to what degree the population is helped or harmed by the change. Since ATP measurements isolate the living population, ...
