Hi there, We have a plant that manufactures iron furniture. The iron bars come from the provider plant with a cover of mineral oil. After cutting, folding and putting together the pieces, there is a rinse process with water and detergent to take out the oil cover. The remaining emulsion of water+detergent+oil is gathered into a recipient, and is reused for 15 days, when the solids are separated and the remaining liquids discarded. I would like to know if there is a substance or a particular chemical that would allow us to break the emulsion physically separating the phases so we can remove the oil through a mecanical method, prolonging the useful life of the water we are using and obtaining a less contaminant residue. Thanks!
