Latest Patents

One of Edward's latest patents is titled "Methods and systems for treating vinasse." This patent discloses methods that treat vinasse to generate usable water. The process involves providing vinasse, reacting it with persulfate to create an oxidized mixture, and further treating this mixture with peroxide. The pH of the resulting mixture is adjusted to above about pH 6, followed by the addition of an inorganic coagulant and a low molecular weight cationic polymer to generate solid particles. Finally, these solid particles are removed to produce a liquid fraction.

Another significant patent is "Methods and systems for reducing biofouling of microfiltration membranes." This invention outlines systems and methods to mitigate biofouling caused by biological substances. The methods include providing impound water containing biomolecule-based exopolymeric substances, reacting it with calcium oxide or calcium hydroxide, and encapsulating the exopolymeric substances into filterable non-tacky particles. These particles are then removed through microfiltration, preventing biofouling of the membranes.
