Abstract:

Advanced wastewater process technologies offer power companies a feasible approach to compliance with national and state regulations. This paper presents two similar installations, where an ultrafiltration process is being applied after a biological treatment process to remove heavy metals such as mercury, along with TSS for final discharge. We present how the ultrafiltration (UF) process enables the power company to meet and exceed the Effluent Limitation Guidelines (ELG) regulations. Additionally, we present how this technology enables the opportunity to reuse the water in a future scenario. From April 2017 through July 2017 a pilot scale UF was installed at a facility where a biological process was currently in operation; this paper compares the hydraulic performance and effluent quality of that pilot with the full scale UF system currently being installed at this facility along with a sister facility which uses the same process. The UF system performed quite well from a hydraulic and filtrate/permeate turbidity perspective as noted in the table. Analysis of the pilot UF filtrate presents data showing greater than 89% removal of mercury, nearly complete removal of total suspended solids (TSS)/turbidity. Other contaminants of concerns such as selenium and nitrogen were removed to the desired level within the biological process. We present a detailed analysis of the UF pilot and the two full scale UF systems which are presently being installed. We will demonstrate in this paper that UF is a viable solution which enables power companies to ensure regulatory compliance for current and proposed regulations but that UF provides an enabling technology for future reuse options to the power companies.
