Optimizing Carbon-based Advanced Treatment for Potable Reuse
Many utilities are looking towards treatment strategies that do not use reverse osmosis because of the difficulty and cost associated with disposing of the brine concentrate stream. This interest in treatment alternatives can stem from a lack of brine disposal options due to location (e.g., inland facilities), regulatory limits on discharges, better alignment with finished water quality requirements, or a desire for reducing energy needs as well as capital and operating costs.
Carbon-based advanced treatment (CBAT), such as biologically active filters (BAF) is often proposed for utilities looking to implement potable reuse when FAT solutions (Full Advanced Treatment with MF/RO/AOP) cannot be sustainably used. Additionally, while CBAT technologies are key, the feasibility of non-FAT processes also relies heavily on careful consideration of the entire treatment train, including any upstream or downstream processes. There is a need to better optimize current approaches, understand pathogen and chemical removal, develop approaches to address salinity, and develop guidance on how to integrate these systems into a community’s water supply portfolio.
