The wastes from beet sugar manufacture include (1) beet washing water, (2) diffusion water, (3) lime sludge, (4) Steffens waste. The extracted beet pulp which might be considered a waste is dried and fed to cattle. The beet wash water can be recirculated and the sand, mud, etc., removed. The diffusion water may be treated with lime and disposed of on sand filters. The lime sludge may be settled and the precipitate used as anti-acid on land. The Steffens waste which amounts to approximately 2l0,000 gallons for 1,000 tons of beets is the most concentrated and most difficult to handle.
