Alternative procedures for the disposal of waste calcium bisulfite cherry processing brine were investigated. SO 2 concentrations in waste brine can be reduced to several hundred ppm by neutralization with lime and filtration or sedimentation to separate precipitated CaSO 3 . Lower SO 2 concentrations can be achieved by oxidation with H 2 O 2 . Anaerobic storage of sludge and supernatant from neutralized brine may produce objectionable odors. Brine to be disposed in deep wells should be pretreated by neutralization and sedimentation. Substitution of Ca(H 2 PO 4 ) 2 · H 2 O for CaCl 2 in brine formulations to eliminate chloride from processing waste was not feasible.
