Abstract
Already-treated sludge is fed back into incoming sewage, and is effective to supply nutrients needed for the microbiological breakdown of the sludge. The feedback sludge has a solids content of 10% or more, and has been sheared and heated to drive its viscosity down to 10,000 cP or less. In sludge done that way, nutrients are preserved and presented to the sewage to be treated in highly liquidized and solubilized form, whereby the nutrients are very bio-available to the microbes in the sewage. Large improvements in the elimination of biomass can result.
