| dc.description | Processing of sugar beets requires large amounts of water for transporting and washing
beets, for cooling and other uses. In addition, the beets themselves yield some 80 % of their weight in water. All of these waters become polluted
in the manufacturing process and represent a disposal problem. This is particularly true in a
cold -climate in which biological activity, necessary to reduce the pollution levels, is low for much of the year. In 1970, the commont practice in the Red River Valley
area of North Dakota and Minnesota was to pond these wastes in large lagoons and to release them at the time of the spring flush of the fivers. Under
then new proposals, federal and state pollution standards, the then current method of disposal would not be possible. The industry was testing ways to minimize the water requirements
in their plants, and other processing modifications, but a disposal problem would still exist. One method of disposing of sugar processing wastes was by spray application over soil. This method was reviewed in this paper. The study concluded that It should be possible to dispose of appreciable volumes of sugar refining wastes by spray application to cropped Fargo silty clay. No short term, one season, deleterious effects were noted on either the soil or on the plants cropped. | |
