The ChemScan Alkalinity Analyzer from ASA Analytics provides consistent chemical analysis for process control and optimization in multiple stream process monitoring of difficult or dirty samples. It requires minimal training and provides continuous real-time online analysis, enabling chemical composition measurement of liquid water or wastewater processes. It can monitor plant samples from raw water after influent screening, settled water after sedimentation basins, filtered water after mixed-media and biological filter cells, as well as finished water. It can also monitor wastewater for alkalinity deficiencies in plant influent or for alkalinity changes related to nutrient removal processes. It has a fully automatic mode for routine monitoring of process streams, filtration system, Modbus communication and digital input control for remote control operation. Internal fast sample loop and rapid reaction electrodes provide fast analyzer response. 262/717-9500; www.asaanalytics.com
