Systemair Ecology Unit & Odor Systems

Ecology Units Why?

Ecology units are ventilation equipments whose use is recommended in kitchen exhaust systems , which serve to clean greasy and dirty exhaust air . With the increase of environmental consequences in the 21st century , severe restriction have been imposed on the release of industrial wastes to the environment , and particularly on the release of flue gas and kitchen exhaust systems to the atmosphere. It is known that the volatile organic compounds ( VOC ) and other particular based substances in the kitchen exhaust systems creates a huge pollution in the air . in many countries , significant restrictions have been imposed on the release of odorous substances to the atmosphere by the regulation issued by the Ministeries of the Environment.

With the introduction of the new residential concept in big cities the rise in so-called “ all-in-one “ projects has led to some problems with air quality . This is because the concentrated kitchen exhausts from the large restaurants and dining areas in these projects have a negative impact on the daily functioning of people occupying the residential , office , and hotel areas that are in close proximity to these areas.

Odor Control units (carbon based systems).

Odor generated from wastewater systems is from hydrogen sulfide (H2S), which is released in the form of a gas.  In addition, hydrogen sulfide can lead to corrosion in collection systems and wastewater plants, leading to dangerous leaks. Several emission sources need odor control equipment, e.g. such as pump stations, wet wells, sludge dewatering, manholes, air valve chambers etc. Sewage and Effluent odor consists of mainly hydrogen sulphide & H2S is dangerous to be released to the environment. Hydrogen sulphide,  the gas,  also contains organic sulphur components  (mercaptans,  hydrocarbons)  and ammonia.

Odorous compounds such as VOCs (Volatile Organic Compounds), H2S and Volatile Fatty Acids (VFAs), can be found in kitchen ventilation and a wide array of different industries. Although the odors do not necessarily impose physical health problems, malodors disturb the surrounding, resulting in complaints towards the source.

Carbon based odor control units are the most basic and commonly used odor control units. In this type carbon medium is utilized for odor and other gaseous removal. These are mostly used in small sized STP, pumping station, wet wells and sludge holding tanks. It occupies less space, easy to operate and maintain. It has 3 stage system pre filtration (demister), ventilation and carbon media. Once the odor /air is passed through the activated carbon medium, allowing the process to occur releasing clean air.

Activated carbon removes unwanted odors by acting as an adsorbent which will trap the odor inside the activated carbon and retain it. Activated carbon is a great adsorbent because of its huge surface area. Virgin activated carbon is excellent at removing unwanted and harmful odors, pollutants and VOCs by both absorbing and adsorbing.
