Reverse Osmosis Membrane Fouling Data

The Orange County reverse osmosis (RO) dataset contains data collected daily from 21 units of RO membranes from January, 1, 2019 to January 13, 2020. They are categorized into seven banks (a.k.a., arrays) labeled with a letter A to G, and each one is further split into three stages (1 to 3). The number of membrane elements installed in each stage of the array are 77, 49, and 24, respectively. The purpose of this dataset is to investigate the impact of influent water quality, seasonality, and temperature on membrane fouling in the third stage of each bank.
