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 dependent upon the identified risks (associated with the individual site activity or discharges from neighbouring industry).
Surface Water Abstraction
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
- pH, Conductivity & Dissolved Oxygen
- Colour (Hazen)
Waste-water Applications
Many industrial sites 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)
- Ammonia
- pH & Conductivity
Sewage Works Inlet Monitoring
Municipal sewage works located in heavily industrialised areas may also need to monitor the inlet for key parameters that are:
- Total Organic Carbon (TOC)
- Ammonia
- pH, Redox & Conductivity
DO, pH, conductivity & turbidity probes mounted into PVC breaktank
Non-contact oil on water detection
