•Case Study: Multi-Barrier Treatment Plant Improves Performance On Variable Water Source
By Siemens Water Technologies
Challenge
The City of Versailles, IN operates a surface water treatment plant for their drinking water supply. The water source is a reservoir that has variable organics and solids loads depending on weather conditions. The turbidity is typically between 25 to 100 NTU, but due to rain events, can increase to over 400 NTU and remain there for more than one day. Prior to 2007 they used two conventional packaged treatment units consisting of two-stage flocculation, tube settling and granular media filtration.
During normal turbidity conditions, the units performed to acceptable levels. However, during spiking conditions, performance deteriorated and the filter run times were reduced to unacceptable levels. In addition, the existing package treatment units were showing signs of corrosion, requiring repair or replacement. The City hired the consulting engineering firm of R.E. Curry, Inc. to investigate new treatment options to address these concerns as well as increase treatment capacity.
