Switching from a membrane-type dissolved oxygen (DO) probe to new, breakthrough luminescent technology has brought tighter control to the conventional aeration system serving the Holland Area Wastewater Treatment Plant. Plus, a four-month trial demonstrated that the new luminescent DO (LDO) probe performs well monitoring high-DO effluent from the facility's pure oxygen system. Until now, it had been difficult for the plant to find a reliable online measurement instrument for this environment.
