摘要： A beet juice treatment method in which reaction products are recycled. Beet juice is first prelimed with lime and CaCO.sub.3 to produce first and second juice fractions. The second fraction contains flocculated materials, and is combined with CO.sub.2. Solid flocs and calcium carbonate reaction products are removed from the second fraction. The second fraction and first fraction are then recombined to produce a third juice fraction which is combined with lime in a main liming stage for additional purification. The third fraction is then supplied with additional CO.sub.2 to generate a CaCO.sub.3 sludge product. The sludge product is divided into first and second portions. The first portion is reused in the preliming stage. The second portion is converted to regenerated lime for reuse in the main liming stage and possibly the preliming stage. These steps reduce waste production and provide economic benefits.
