Many water quality determinands are monitored continuously in water treatment including: temperature; turbidity; colour; free chlorine; conductivity; pH and metal-icon concentration. The overall capital and revenue cost is substantial and yet may include measurements with relatively or reliability or accuracy.
The objectives of the research undertaken by WRc for a group of 6 Water Utilities were to:
- Identify current monitoring practice in relation to water treatment processes
- Identify, develop and demonstrate optimisation in water treatment monitoring attainable through:
- The application of additional low cost measurements (alone or in combination)
- Better application of existing measurement information.
Reduced cost of monitoring and reduced risk of water quality failures through making best use of measurement technology.
