Abstract:
1. A wastewater disinfection apparatus comprising: a source of ozone; an ozone pressurization system configured to pressurize said ozone; and an ozone permeable diaphragm established in a lower one-third of a wastewater treatment tank and configured to entrain said ozone in wastewater in said wastewater treatment tank, wherein said diaphragm has a substantially planar gas ejection surface characterized by a diaphragm normal vector having a normal vector terminus at said substantially planar gas ejection surface and a linear projection therefrom, wherein said wastewater treatment tank has a vertical centerline, wherein said diaphragm is established such that said diaphragm normal vector has a horizontal component that is not in alignment with a wastewater treatment tank radius that emanates from said vertical centerline and passes through said normal vector terminus, and wherein said horizontal component of said diaphragm normal vector forms an angle of from 20 to 24 degrees with said wastewater treatment tank radius.
