The ENVIROS METHANE STRIPPING WEB SITE
For new Methane Stripping Plants (MSPs) which will be located close to property, or where the planning authority or Environment Agency request an odour risk assessment, Enviros offers an odour risk assessment service.
In order to carry out a site specific odour risk assessment it is necessary to mimic as closely as possible the conditions under which the full scale plant will produce a potentially odorous off-gas from the aeration process.

“The offgas vented from a methane stripping plant may give rise to complaints about odours from some leachates unless suitable odour control is provided.”

To do this we use our “wheely bin based” trial plant equipment, as shown elsewhere on this web site, and run the trial MSP for several hours using fresh site leachate, until the off-gas from the plant reaches full strength and steady state conditions. At this time the air being expelled from the trial will contain the odour which will be experienced from the full scale plant.
An air sample is then obtained which is sent to an odour panel. Enviros then incorporates the report on the impact of the odour obtained from the odour panel with information on the test system used, and writes an odour risk assessment based upon the predicted impact of the full scale plant on the sensitive receptors which will have been identified at that site.
An Odour Risk Assessment Report is provided by Enviros. The report will include a conclusion which will either demonstrate that no significant odour impact will occur, or if an impact is identified, it will propose ameliorative measures, such as the provision of a suitable odour removing bio-filter.
Enviros are cost effective in the provision of these tests, as we have the training, and test equipment stored ready for use. The report we produce, being obtained from an independent consultant, is authoritative. The reports we have provided have been accepted by the EA, and/or Planning Authority, on all occasions to date.
Enviros technicians will normally set up, test, and dismantle the test rig in one day.
