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, the response of this measurement to process changes is shown in real time. As such, process variables can be adjusted according to this feedback in order to achieve enhanced process control. This can translate to significant cost savings opportunities such as improvement of solids viability (lower solids handling costs) and reduced electricity consumption (optimized dissolved oxygen concentration resulting in reduced blower horsepower).
While the cost savings opportunities in wastewater treatment are numerous, one of the most common goals that wastewater treatment managers have when initiating a routine ATP monitoring program is to maintain process stability and detect changes in influent quality. In many industrial wastewater treatment plants, one or more influent streams that feed the treatment process can become toxic with little or no warning, thereby posing a serious risk to the biomass in the reactor. If severe enough, this influent toxicity can kill a large portion of the biomass, thereby initiating a process upset that often results in discharge violations. The key to overcoming this threat is early detection so that preventative action can be taken to minimize the damage done, and in some cases, prevent the upset from occurring.
