Electroflotation is a promising technology for simultaneous disinfection and removal of floatable constituents of food process water or fluid products. A bench‐scale electroflotation apparatus was constructed. The device demonstrated that disinfection was affected by the presence of chloride and the applied current. It was effective in disinfecting Escherichia coli when chloride was present at levels at least 5.6 mg L 1 at 0.8 A but not at 0.1 A even with 260 mg L −1 chloride. Experiments on salt solutions showed that chlorine generation efficiency increased with chloride up to 260 mg L −1 and also with current, reaching a constant value above 0.4 A. Gas generation efficiency was relatively constant. Appropriate selection of operating conditions may allow optimization of disinfection and separation in electroflotation.
