Longview Pipe Loops

Confluence has been involved in a variety of projects related to the treatment and optimization of groundwater supplies. Projects have ranged from research-based collaborations teaming multiple utilities and university research teams, to municipal water systems with one well as a source of supply. Work on these projects has involved a host of sub-specialties, such as:

  • Fe/Mn oxidation/filtration
  • Fe/Mn sequestration
  • Arsenic removal
  • Chromium removal
  • Sulfide destruction
  • VOC removal (stripping, adsorption)
  • Ammonia adsorption/breakpoint removal
  • Chlorine demand/decay studies
  • Booster chloramination and breakpoint free chlorination
  • CO2 removal (pH adjustment) using membrane contactor and diffused aeration
  • Pipe loop pilot design & implementation
  • Blending analyses
  • Dissolved Oxygen injection
