Description
The Castaic Lake Water Agency operates two water treatment plants that treat the same surface water supply–California State Water Project water stored in Castaic Lake. The older, 25 million gallon per day (mgd) Earl Schmidt Filtration Plant (ESFP) employs a conventional treatment process with chlorine oxidation. The newer, 30 mgd Rio Vista Water Treatment Plant (RVWTP) uses an innovative high-rate serial filtration treatment process with ozone oxidation. This circumstance provides an opportunity to compare the performance of these two treatment processes treating a similar source water. Castaic Lake water is characterized by low turbidity (typically below 2 NTU) and a trihalomethane (THM) formation potential exceeding the existing total THM MCL of 0.1 mg/L. This paper compares the simultaneous performance of the innovative RVWTP during its first two years of operation with the performance of the ESFP treating the same source water. The paper also includes an evaluation of the performance of the serial filtration process in reducing assimilable organic carbon (AOC) and biodegradable organic carbon (BDOC).
