Methods of treating waste streams

A process for treating a lipid stream comprising one or more lipids and water, wherein the process comprises:

• a) heating the lipid stream to a temperature sufficient to release the one or more lipids from the water and forming an aqueous phase comprising water and an oil phase comprising the one or more lipids;
• b) decreasing the pH to a pH sufficient to dissolve at least a portion of one or more metals present;
• c) optionally decanting at least a portion of the one or more lipids;
• d) optionally treating the oil phase, the aqueous phase, or both with aluminum ions released by electromagnetic field reaction of an aluminum rod acting as an electrode operating at greater than 4 volts and less than 20 volts;
• e) treating the oil phase, the aqueous phase, or both with an electrode system wherein the electrode system comprises a titanium and a ruthenium oxide coated titanium electrode system operating at greater than 1 volt up to 50 volts;
• f) attaching hydrogen bubbles to at least a portion of the one or lipids such that the hydrogen attached lipids surface;
• g) generating peroxides, hyperoxides, or a combination thereof to oxidize one or more oxidizable components comprising metal, living organisms, organic materials, BOD, COD, or any combination thereof,
• h) separating the oil phase from the aqueous phase;
• i) increasing the pH to a pH sufficient to precipitate at least a portion of the metals while avoiding substantial mount of emulsion formation;
• and
• j) filtering solids comprising metal precisipiates, organic matter, or any combination thereof.
