Bench‐Scale Evaluation of Innovative Arsenic‐Removal Processes
Microsand‐ballasted coagulation provided promising arsenic (As) removal in bench‐scale tests of simulated drinking waters; however, no synergistic benefits were observed when microsand‐ballasted coagulation was used as a pretreatment to microfiltration. Polymer was critically important to the performance of the microsand‐ballasted coagulation process. Although coagulation/microfiltration typically provided the best As removal at a given iron dose, microsand‐ballasted coagulation processes are likely to be a promising alternative method of As treatment for many utilities if expectations of lower projected capital and operating costs for microsand are proven valid.
