Challenge: Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are traditional parameters analyzed in the laboratory to determine organic matter in water and wastewater. Wastewater facility operators need to have constant data to monitor their discharges and optimize treatment processes (biological treatment, chemical dosing, etc). The requirements of BOD and COD analysis prevent them from being implemented as control parameters, however. The BOD five-day analysis time requirement...

Minimising costs through measurement of CO2 concentration. Both water suppliers and water users need to know the quality of the water they are supplying, using and disposing of so as to minimise their costs. One measure of water quality is the organic carbon content (TOC). TOC is measured by oxidising the organic carbon to produce CO2 which is then measured and the value converted into a TOC measurement. Edinburgh Sensors supply sensors to measure the CO2 concentration produced by oxidising the organic carbon...
