Two on-site trials were conducted at the City of Yamhill facultative sewerage lagoon system. The first flow-through trial was performed during the winter months, to denote any adverse affects of cold water/weather on the ability to reduce the pollutants. A follow-up trial was then performed during the height of the summer months, when facultative, suspended algae growth would be at its highest.
The winter trials were performed on the first, incoming sewage anaerobic lagoon, with a follow-up on the fourth and final lagoon prior to disinfection and discharge. The summer trial was only performed on the final stage lagoon, as nutrient loads were approximately the same as the winter first stage lagoon. The primary issue was to determine the economics of employing a flow-through electrolytic oxidation system in order to handle higher flow rates, and either remove or reduce the size or operation of the facultative lagoon(s); and due so at a reduced capital and operative cost then conventional brick and mortar wastewater treatment plants.
