The City of Hannibal, Missouri, sought a cost effective disinfection technology to meet upcoming National Pollutant Discharge Elimination System (NPDES) permit. Read the full case brief to learn how the full-scale test confirmed that VigorOx WWT II is a cost effective solution for this plant to achieve the disinfection goals.
The City of St. Helena, CA, uses a municipal wastewater system with aerated lagoon and an average flow rate of 0.5 million gallons per day. The performance of existing chlorination process becomes less effective during some periods of summer and fall months, and the city sought a cost effective technology that could provide more stable disinfection performance over a broad range of pH conditions and could easily retrofit the existing system.
The Valley East Wastewater Treatment Plant (Sudbury, Ontario, Canada) hired an engineering firm to evaluate three disinfection options including chlorination followed by dechlorination, ultraviolet (UV) light irradiation and VigorOx WWT II. Read the full case study to learn more.
Wastewater treatment plants are required to disinfect effluent prior to discharge in order to destroy any pathogenic organisms present and minimize public health concerns.
