Lab and Online Charge Analyzers for Challenging River Water Coagulant Dosing |
The water treatment plant in King, NC has a source water that is quite a challenge to treat. The Yadkin River can experience quick and substantial changes in turbidity (NTU) and organics (TOC). Subsequently the required chemical feed dosages can be significantly impacted in a short period of time.
Looking for the appropriate technology to help optimize their coagulation, settling, and filtration process, allowing them to produce the best water for their customers, they turned to two products from Chemtrac: the Laboratory Charge Analyzer (LCA), and the online Streaming Current Charge Analyzer (HydroACT Analyzer, and the DuraTrac 4 Streaming Current Sensor). |

The Laboratory Charge Analyzer (LCA) is an essential coagulation optimization tool for the water treatment professional. The LCA allows the user to determine the ideal coagulant dosage needed to achieve optimum NTU and TOC reduction in less than 5 minutes typically. The LCA can also be used to determine the dosage rate of additives like lime or caustic when used to raise coagulation pH of low alkalinity waters. The larger sample size capability of the LCA allows the user to accurately titrate samples using undiluted coagulant, which is a very important feature when working with highly reactive coagulants like PACl or ACH. Options for pH measurement and auto-titration are also available.
