Latest Patents

Masciola holds a patent for a wastewater mercury removal process. This method is designed to effectively eliminate ionic, organic, and elemental mercury from wastewater streams, particularly those generated from hydrocarbon processing. The process involves four primary removal steps. Initially, a mercury precipitant is added to convert dissolved ionic species of mercury into a water-insoluble form. The majority of these precipitated solids, along with other forms of particulate mercury, are then removed through gas flotation. Following this, additional removal of particulate and precipitated ionic mercury is achieved using media filtration. Finally, activated carbon is employed to eliminate any remaining dissolved ionic mercury species, as well as elemental and organic forms of mercury. This innovative method highlights Masciola's expertise in environmental engineering.
