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).

In addition to this featured video, an automatic coagulant dose-titration demo of the LCA can be found at https://www.youtube.com/watch?v=CdVVoIOWFUg.
