Odour Monitoring and Measurement

Odour Emissions and Removal

The handling and treatment of waste water and other organic material can very often cause the emission of offensive odours into the environment. The odours are predominantly caused by hydrogen sulphide (H₂S) gas which is detected by the human nose as a strong odour even when levels are only a few parts per million or less.

There are many techniques used within the industry to control or remove this gas but almost all of them require the injection of expensive chemical neutralisers and/or the use of energy to pump the odorous air into a chemical scrubbing system. Whatever the method used, it is critical that the process is run efficiently and economically. This can only be done by making gas measurements both before and after the treatment process.

Monitoring and Anaysis Equipment

Gas Data's GFM130 multi channel gas analyser is available with a very low level Hydrogen Sulphide (H₂S) sensor capable of detecting levels down to 0.02 ppm (parts per million).

This is used to make manual measurements in and around plant where there is thought to be a problem i.e. where a neutralisation process should be operational but is defective or where such a system is needed. With this data trials can be run to determine the best solution. After the solution has been found, its control is critical to avoid unnecessary running costs.

An ideal solution is to install a Gas Data LMSp Hydrogen Sulphide (H₂S) analyser configured to provide signal outputs for the control of the gas only when excessive levels are reached.
