Abstract
A method of removing food soils from a recirculated washing solution includes adding a flocculating agent to the recirculated washing solution and separating the particulates from the recirculated washing solution using a hydrocyclone. The flocculating agent causes a portion of the food soils to combine into particulates having a higher density.
Claims25
A method of removing food soil particles from an aqueous solution in a dishmachine comprising:
- (a) performing a wash cycle with a wash solution comprising a detergent composition;
- (b) forming a used wash solution comprising food soil particles;
- (c) collecting the used wash solution;
- (d) adding a flocculating agent to the used wash solution to agglomerate the food soil particles into agglomerated particles;
- and
- e) separating the agglomerated particles from the used wash solution using a hydrocyclone.

A method of removing food soils from a solution in a dishwashing machine comprising:
- (a) forming agglomerated food soil particles in the solution;
- (b) separating the agglomerated food soil particles from the solution using a mechanical separation into a concentrate stream and a permeate stream, wherein the agglomerated food soil particles are separated based on the density of the agglomerated food soil particles;
- and
- (c) combining the permeate stream with the solution.
