At the Irvine Ranch Water District, two types of secondary treatment are utilized: a sludge and Dual Media Filters (DMF) process and Membrane Bioreactor (MBR) process. This study was proposed to analyze the electrical conductivity (EC) of each secondary effluent and possible reasons for differences. After testing the two effluents using an electrical conductivity probe and ion chromatography, it was discovered that there is no significant difference between the two, though secondary treatment raises the nitrate levels in general.
