The study presents information about the measurement techniques used for the assessment of air quality in terms of the olfactory intensity resulting from the operation of municipal sewage treatment plants. Advantages and disadvantages of the measurement techniques used are presented.

In the modern world of wastewater treatment , control of odors has moved from an afterthought to a primary design consideration for most collection and treatment facilities. As development encroaches on our facilities and our new neighbors become less tolerant of nuisance odors, wastewater professionals have found the need to address odor as a primary concern in the design and operation of collection and treatment facilities. As the attention paid to controlling odor has increased, so has the number of odor control technologies that are available in the marketplace. This paper consists of an evaluation of the qualitative characteristics and the economic properties of the various technologies available for wastewater odor control.

The key to understanding the odour control principle of Statutory Nuisance is that the presence of an odour itself does not constitute a nuisance. The characteristics of an odour which are taken into account when assessing nuisance are odour type pleasantness , odour strength, frequency and duration of release, persistence in the environment and the extent of interference with enjoyment of the amenity of a neighbourhood. There are also cases when although odours are present, the controls measures put in place by the operator fulfil the test of best practicable means bpm or are present due to circumstances beyond the control of the operator such as unforeseen breakdown, adverse weather conditions.

Assessment of hydrogen sulfide emission from a sewage treatment plant using AERMOD

Humans perceive odors by chemical stimulation of the chemoreceptors in the olfactory epitheliurn located in the nose. Odorants are the chemicals that stimulate the olfactory sense. This interaction between sensory cells and volatile molecules, which produces a nerve impulse, enables humans to detect and differentiate between different odors and to detect odor intensity.

Air quality modeling plays an important role in prediction of air pollutants in urban areas. Moreover, it is also an essential component to make crucial decisions in environmental management. Dispersion modeling was employed for the prediction of hydrogen sulfide H 2 S emissions, a neighborhood claimed issue, from Al-Ansab sewage treatment plant STP. Meteorological, elevation data, and H 2 S survey results were implemented into the model. From the site survey study, four different H 2 S emission sources were identified as sewage tanker connection points, biofilter, old odor control unit OCU , and open channels of raw sewage.

Assessment and control of odour nuisance from waste water treatment: code of practice

Wastewater treatment works have the potential to generate unpleasant odours, which can results in annoyance and consequently have a detrimental effect on a local population. Odours in Wastewater Treatment provides readers with a detailed discussion on the basic principles involved in the formation of volatile compounds in wastewater treatment. Accounts are given of recent developments in the sampling and measurement of odours, practical examples in the prediction and dispersion of odorous emissions are offered and an overview of the technologies currently used to contain and treat odorous compounds presented.

The study presents information about the measurement techniques used for the assessment of air quality in terms of the olfactory intensity resulting from the operation of municipal sewage treatment plants. Advantages and disadvantages of the measurement techniques used are presented. Sources of malodourous substance emission from sewage treatment plants were described, and the malodourous substances emitted were characterised. Trends in development of analysis and monitoring of the malodourous substances in the air were also presented. More and more attention is devoted to environmental protection issues, including atmospheric air quality, as a result of the introduction of the principles of green chemistry into the technological practice and other types of human activity, which result from the sustainable development concept. Dynamic economic development contributes to an increased amount of pollutants emitted into the environment, which can have a negative effect on the abiotic part of the environment as well as on living organisms, human health and life. Municipal sewage treatment plants belong to the symptoms of human pressure, which can be particularly onerous Gostelow et al.

 Может.  - Сьюзан пожала плечами, демонстрируя равнодушие. - Мы с ним какое-то время переписывались, - как бы невзначай сказал Хейл.  - С Танкадо. Ты знала об. Сьюзан посмотрела на него, стараясь не показать свое изумление. - Неужели.

Что ж, пожалуйста. Хватит путаться у нас под ногами, вот моя рекомендация. - Спокойно, Джабба, - предупредил директор. - Директор, - сказал Джабба, - Энсей Танкадо владеет нашим банком данных. Дайте ему то, чего он требует.

Сьюзан едва дышала. Отчаянно вырываясь из его рук, Сьюзан локтем с силой ударила Хейла. Он отпустил ее и прижал ладони к лицу. Из носа у него пошла кровь. Хейл упал на колени, не опуская рук. - Ах ты, мерзавка! - крикнул он, скорчившись от боли.
