The objectives of this study were to determine the settling characteristics of solids from sugar beet washing and fluming operations in a clarifier, the filtering characteristics of the underflow slurry from a clarifier and the disposal of the filter cake without subsequent development of objectionable odors. The results of this study were to be used to determine the feasibility of installing full scale filters for filtration of and removal of the suspended solids from the transport water and complete recycling of water. Buildup of organic matter in the water and consequent bacterial growth necessitated the maintenance of high pH by addition of slacked lime. It was necessary also at intervals to add paraformaldehyde to control bacterial growth. Dosages are given. Best conditions for filtration were obtained when, the underflow from the clarifier was heated, the pH was maintained over 10.5 and when the waste lime cake from beet juice purification was added to the feed to the clarifier.
