Benzene Monitoring

Environmental concerns continue to exert downward pressure on the detection limits of monitoring systems. Benzene, along with other aromatics, is coming under increasing scrutiny in the European Union, and the United States is also re-examining current permissible levels.

Continuous Odour Monitoring

Composting sites generate odour nuisances along the site boundaries. The setting up of a continuous odour monitoring system based on eNose technology means operators can get a better understanding of the way unpleasant odour incidents occur and do something about their process to reduce emissions.

Environmental Odour Monitoring

A real-time odour impact monitoring system was installed at the Sivos des 60 Bornes waste water treatment plant (WWTP), which treats the waste water of two towns, St-Hilaire-de-Riez and St-Jean-de-Monts, on the French coast in the region of Vendée. The users’ objective was to minimise odour nuisances generated by pumping stations of the waste-water system and by various components of the WWTP.

Chromatography in Environmental Analysis

Gas chromatography (GC) is a technique used to separate the individual components of a complex mixture. A very small quantity of sample is needed (less than 1/1000th of a gram). The sample is injected onto one end of a chromatography column, down which gas (the carrier gas) is passing (usually helium or hydrogen). The column is situated in an oven. When the oven is cool (room temperature) only volatile compounds that boil at low temperature will evaporate from the sample and travel down the column to be detected at the far end by a detector. As the oven is heated, components of the mixture that boil at a higher temperature evaporate and are transported down the column by the flowing gas. In this way the components in the mixture are separated according to the temperatures at which they boil.

Dry Chemical Odour Scrubbers

Dry chemical scrubbers are uniquely suited for use in collection system pump stations and in waste water treatment plants for the control of odours. They are inherently simple in their operation and function continuously without operator attention for extended periods of time. This type of scrubber, through the use of specialised gas-phase or dry-scrubbing air filtration media types(medias), is essentially able to achieve the complete removal of odours without the need for additional dilution air.

Real Time Odour Monitoring

Odour abatement monitoring using electronic noses The equipment implemented to reduce odour emissions is designed with effectiveness in mind. However, some operating conditions may reduce that effectiveness without an industrial site being able to detect this quickly. Processes that most of the time have low odour emissions may become, under certain weather conditions, a major nuisance source.

Principles of Landfill Odour Emission and Control

Throughout most countries in Europe by far the greatest proportion of waste is disposed of to landfill. In the UK this represents approximately 83% of all waste disposed. Odours from landfill represent the single highest cause of complaint from waste management processes in the UK. These concerns also represent one of the most commonly cited reasons for refusal of extensions and applications for landfill operations. So is this a problem that we should be concerned with or an issue that will fade away as our dependency on landfill reduces and new technologies contribute to managing waste.
