The ChemScan 2150/DC chlorination-dechlorination analyzer from ASA Analytics measures total chlorine residual and dechlorination agent residual, automatically providing operators with timely chemistry measurements. This data can be used to assure process conformance, control energy and chemical costs, improve process performance, and avoid taste and order complaints. Two ChemScan mini analyzers provide an add-on solution to existing plant control systems for analysis of key control parameters used in the wastewater effluent chlorination process. The ChemScan mini LowChlor and the mini Sulfite analyzers, used together, create a complete chlorination/dechlorination monitor and control system. 262-717-9500; www.asaanalytics.com
