ASSESSMENT OF OPERATION AND MAINTENANCE COSTS FOR ULTRAVIOLET DISINFECTION SYSTEMS
Abstract
Ultraviolet (UV) disinfection is increasingly replacing chlorine-based disinfection systems in wastewater treatment to avoid the environmental and safety hazardsassociated with the use of chlorine. In the process of deciding whether to replacechlorine-based disinfection systems with UV systems (and which UV system to choose as the most appropriate and cost-effective), the wastewater treatment plant designer must evaluate the different types of manufactured UV equipment. Though actual capital costs can easily be obtained from manufacturers, operation and maintenance (O&M) costs aremore difficult to accurately quantify. Little current objective information is available toadequately assess operation and maintenance costs.For this project, UV equipment O&M costs were assessed at five operating wastewater treatment plants in the State of Washington. O&M costs for UV equipment power, labor, parts, and chemicals were estimated at each plant through power consumption monitoring, interviews with plant operations staff, review of plant operating records, and on-site equipment observations. Four different types of UV equipment were investigated at the treatment plants. Actual power consumption (kW/MG and kW/lamp)was measured by connection of power monitoring instrumentation to each UV system power source. The information collected in the study provided actual O&M costs foreach system, allowing comparison of disinfection expenses in terms of /MG for each O&M cost source (power, labor, parts, and chemicals) and for total O&M /MG. Analysis of this information provides insight into factors that affect the operation and maintenance of UV disinfection systems.
