AV410 Dissolved Organics Monitor

Brand: ABB Group

AV410 single-channel UV254 low-level dissolved organics monitors (0 to 20 mg-1C) are designed for use on potable water treatment plants. In particular, they can be used to monitor the quality of the outlet from sand and carbon filters to provide a THM precursor measurement.

Long term field trials have shown that maintenance demands on these applications are minimal.
Features
  • Dual input gives two measurements in one instrument, each input can be either high range or low range
    • cost-effective
  • Surrogate color measurement
    • significant savings on operational costs through lower maintenance requirements
  • Savings on alum or ferric are achieved on potable water treatment plants
    • coagulation control cost saving
  • Less alum, less sludge
    • reduced sludge disposal costs
  • THM (trihalomethanes) precursor alert
    • provides advanced warning of increased risk of THM development
  • Automatic compensation for turbidity
    • reduces initial capital expenditure, minimizing operational costs
  • Reagentless operation
    • significant savings in operational expenditure
  • On-line diagnostics
    • cleaner failure, loss of signal, out of sample
