Abstract
A streaming potential apparatus was assembled and tested. Its purpose was to characterize the surface of biological flocs in a wastewater environment. Samples of mixed liquor were obtained from the Passaic Valley Sewerage Commissioners wastewater treatment plant in Newark, New Jersey. Filtered mixed liquor was passed through a bed of the floc particles in the streaming potential cell, and the electric potential across the cell was measured as a function of the differential pressure drop. From these data, the zeta potential was calculated using the Helmholtz equation. Values of -0.88 and -0.44 millivolts were obtained for two mixed liquor samples.
