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
