Water intake protection monitoring for wastewater treatment industry - Water and Wastewater - Water Treatment

Intake protection systems have been extensively installed to protect water treatment works, from ingress of polluted water and waste-water plants from toxic chemical loads. A suitable system typically comprises a suit of instrumentation, measuring key chemical, physical and indicator parameters dependant upon the identified risks, associated with the individual site activity or discharges from neighbouring industry.

Surface water or river sources are particularly at risk from a wide range of contaminants. Borehole abstraction may also be affected by surface water recharge, migrating leachate or saline intrusion. The choice of instruments may therefore vary according to the surrounding industry and the identified potential pollutants.

Typical parameters measured are:

  • Oil On Water Alarm (non contact)
  • Total Organic Carbon - TOC
  • Turbidity Ammonia & Nitrate
  • Ammonia & Nitrate
  • pH, Conductivity & Dissolved Oxygen

Many industrial site have installed biological treatment facilities to treat raw effluent to comply with imposed consents or reduce trade discharge costs. It may therefore be necessary to monitor and divert raw effluent and protect biological treatment processes.

Typical parameters measured are:

  • Total Organic Carbon - TOC
  • Toxicity
  • pH & Conductivity

Municipal sewage works located in heavily industrialised areas may also need to monitor the inlet for key parameters that are:

  • pH & Conductivity
  • TOC
  • Toxicity
  • Phosphate
