Osorno is dedicated to wastewater treatment and is an owner of one of the oldest packaged sewage treatmentsystems in the world called BioCompact®. The wastewater treatment design used by Osorno has not previouslybeen applied to a sequencing batch reactor (SBR) process. The goal of this project is to investigate thechemical and biological process kinetics in activated sludge wastewater treatment systems, with the help ofcombined pH-ORP-T sensors. By employing the Intelligent combined pH/ORP/T sensors made by Osornounder the SBR treatment technology, Osorno will have the opportunity to expand their client base regionallyand their presence across Canada by co-publishing a peer reviewed research paper.The scope of this project is to perform a bench-scale baseline comparison of the existing SBR treatmentprocesse with enhanced nutrient removal by implementing mixing, aeration, and fixed film processmodifications together with advanced on-line measurements, and associated control system, using thecombined pH-ORP-T sensors made by Osorno. We will investigate: 1) operating conditions and wastewatercharacter at HWWTF; 2) the operational enhancements for nitrogen, phosphorus removal; the aerationprogramming under the different SBR processes 4) the chemical dosing to maintain optimum pH-ORP in theprocess; 5) Investigate the automation and controls needed to achieve nutrient removal.Findings from this research project will provide a much-needed SBR treatment performance baseline withrespect to the process enhancements that are currently only found in the laboratories of research universities inCanada. With an improved understanding of what specific aspects of SBR chemical and biological treatmentkinetics are deficient, appropriate process enhancements may result in SBR design upgrades that will allowsmaller population centres to retrofit and operate their existing facilities in a more cost effective manner, whilesatisfying their environmental license effluent limits.
