ABSTRACT:
Method and apparatus for controlled growth of precipitates in systems requiring separation of undesirable contaminants from a solution prior to treatment with a coagulant aid. Cane sugar juice, as exemplary, is introduced at an elevated temperature into an apparatus having means for maintaining a mildly reduced pressure. The apparatus has a conical funnel with a downwardly extending tubular outlet. Means are provided for incrementally and continuously introducing a chemical treating agent into the juice, as it flows down the funnel toward the outlet. Juice discharge means allows for control of the retention time in the tower. The method of treating cane sugar juice is as follows. Cane sugar juice, preferably partially limed, is introduced into the top of the funnel at an elevated temperature and allowed to flow by gravity flow through the funnel, while additional milk of lime is incrementally and continuously introduced into the cane sugar. The cane sugar juice flows downwardly through an outlet and then upwardly to allow for controlled formation of insoluble precipitate particles.
