Application of Cryptosporidium Sensor and Bromate Ion Sensor to Optimization of Produced Wastewater Reuse As Drinking Water Source

This study summarizes the effectiveness of online and automation technology to monitor Cryptosporidium and bromate ion. A Bromate Ion Sensor and CrypotSensor developed for online and automation measurement were evaluated for their performance with water samples. The Bromate Ion Sensor: fluorescence measurement of bromate ion concentration showed a strong correlation (r2 =0.92) with the analytical method by IC-PC. The CryptoSensor: OFCM measurement after FITC-staining, was capable of performing enumeration of Cryptosporidium oocysts and Giardia cysts simultaneously. . Online data acquisition by these two sensors will expand the possibility of the reuse of produced wastewater/spent water as drinking water source water.
