Evaluation of Full-Scale Sugar Beet Transport Water Solids Dewatering System

摘要

The objectives of this study were to evaluate a full-scale vacuum filtration system for dewatering solids removed from the transport water in an operating beet sugar plant in terms of operational reliability and efficiency, economics, and ultimate disposal of the dewatered solids. At the plant study site the solids in the beet transport water are removed in a clarifier and piped to the Mud House. Waste lime mud from the sugar processing is added to the clarifier underflow to serve as a filter aid. The combined sludge is dewatered on two vacuum filters. The filter cake is pumped to a storage lagoon adjacent to the Mud House.
