In poultry processing, carcasses are chilled in water that is replenished at 1.9 L/bird. The high costs of water usage, wastewater treatment and refrigeration energy have raised the need for developing means for the safe reuse of processing water. An electroflotation device that concurrently disinfects and removes solids from overflow water was developed. At a charge of 280 C/L, electroflotation reduced aerobic bacteria and coliforms by 6 and 5 log CFU/mL, respectively, 1000‐fold more efficient than dosing with 150 mg/mL chlorine. Electroflotation removed 82% of the suspended solids and 14% of the soluble organic matter without the use of flocculant, indicating its potential for treating overflow water for reuse.
