Chemical Oxygen Demand (COD) measurement

Chemical Oxygen Demand (COD) measurement is an important parameter used to monitor industrial discharges to demonstrate compliance to imposed consents. Whilst COD measurement may be performed on a discrete sample, the ability to monitor effluent discharge on a continuous basis has many advantages. Firstly the continuous data trend may indicate specific events or times during the day when the process becomes non-compliant. Additionally, continuous monitoring is much more representative than spot sampling allowing identification of product loss or processes requiring particular investigation.

The discrete COD measurement typically takes around 30 minutes to perform which limits it's usefulness as a control parameter. Our company manufactures TOC analysers which can continuously perform Total Organic Carbon measurement; a good COD indicator.

The Protoc TOC analyser provides continuous measurement enabling real time reporting, allowing process control and data trending. Engineers and scientist may then simply view this information to appraise site performance and allowing subsequent process optimisation. The analyser should be installed within an existing building or analyser kiosk required to provide frost protection. Our company can also engineer small enclosures complete with lighting and plumbing to allow a fully fabricated solutions.
