The water used to wash sugar beets contains a significant solids loading. Many factories discharge the water to ponds or lagoons to allow slow settling, digging the settled solids out each year. The beet wash decanters supplied by Broadbent are designed to process the clarifier underflow and remove the majority of the suspended solids. This significantly reduces the solids loading in the ponds and removes the need to dig out the ponds each year.
When combined with other effluent treatment equipment the beet wash decanter can reduce or eliminate the need for ponds to recover the solids from waste streams avoiding environmental issues from odours as well as releasing land for other purposes.
The photograph below shows the discharged solids from the decanter instalation shown above. The solids produced by the decanter are 'truckable'.
