Sugar beet washings

The use of polymer combinations for the improvement of flocculation efficiency is not new and was described earlier [1-24]. Two or even more components, added in sequence as flocculant systems, produce synergistic effects on the flocculation. Many different systems have been applied in the paper industry, and also in other fields like peat dewatering [1], flocculation of harbor sediments [2], wastewater [3], or sugar beet washings [4]. 

Excess soil from samples such as a root crop should be removed with light brushing but never washed prior to placing the samples into collection bags. In the case of mature root crops, e.g., sugar beet, the roots and leaves should be processed separately, and the weights of leaves and roots should be determined separately in the field. 

Sugar (sucrose) is obtained from either sugar beets or sugarcane. Sugar beets are traditionally diffused with water to extract the sugar from the pulp. The sugar is then crystallized, mechanically separated, and washed to produce white sugar. 

Extraction and purification. An alcohol-insoluble residue was prepared from sugar-beet pulp. Products successively extracted from this material were water-soluble pectin (WSP), oxalate-soluble pectin (OXP), acid-soluble pectin (HP) and alkali-soluble pectin (OHP). Extractions were done according to the procedure described by Barbier and Thibault (7). The pectins were purified by chromatography at pH 4.8 on Whatman DEAE-cellulose DE 52 under the conditions described by Barbier and Thibault (7). As the alkali-soluble pectin binds irreversibly to this column, this fraction was purified by precipitation with CuSO and extensive washing of the precipitate. Cupric ions were subsequently removed by dialysis against Na2EDTA at pH 4.8. 

Sugar beets are harvested in the fields, washed, and cut into small pieces. The beet chips are then soaked in water and pressed to extract the sweet juice in them. The juice is boiled and the liquid evaporated to obtain crystalline sucrose. The solid material remaining from this process can be used as animal feed. 

The sugar beet on arrival at the factory is washed, sliced and soaked in water, which removes most of the sugars. After extraction of the sugar, the residue is called sugar beet pulp. The water content of this product is 800-850 g/kg the pulp may be sold in the fresh state for feeding farm animals, but because of transport difficulties it is frequently dried to a moisture content of 100 g/kg.
