Tobacco produces a strong, characteristic smell. The process airflow from the tobacco industry mainly comes from drying the tobacco leaves. Through central air exhaust systems, all air submitted from the drying process is blown outside. Because this is a very large waste airflow, odour nuisance in the neighbourhood is likely.
Th turn key plant is composed by three different wet stages.
The first stage is a venturi jet scrubber to collect dust and particles, then the second and third stages are deputed to absorb bad smells, such as H2S, Ammonia and Ammines. The absorption takes place thanks to the injection of chemicals (such as Sulphuric Acid, Sodium Hypochlorite and Sodium hydroxide.
We can treat the air streams from waste management plants, MBT (Mechanical Biological Treatment) reception and composting areas, Waste Water Treatment Plants (WWTP), Refuse Derived Fuel (RDF) Plants, gasification of waste, syngas, torrefaction, gas engines and biogas upgrading.
In waste management plants and WWTP, we remove the odors that may be causing a nuisance to neighbors, with bioreactors using Biomass to degrade odorous components and where odors are particularly intractable or VOC emissions higher,...
Citto Activated Carbon 'Air Series' offers a range of standard, impregnated, and specialized activated carbon products for a wide spectrum of air purification applications. The dynamic product array of the Citto Activated Carbon 'Air Series' is developed to meet stringent emission control regulations as well as safety standards for emerging respiratory technologies effectively removing nuisance odors, volatile organics, and hazardous chemicals from air and gas streams.
Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. At the entrance of the waste water plants, where the waste water arrives, strongly smelling...

The real-time monitoring of odorous gases or more classical pollutants emitted by industrial sites (wastewater treatment plants, refineries, landfills, etc.) appears nowadays as a requirement, in order to optimize the site process and operations, or communicate towards the neighborhoods and local public bodies.
While emissions can be measured directly at the source (in the stack, exhaust, etc.), ambient air measurement all around the sites provides a better accuracy and anticipate pollution episodes. This is why...
