Along with sugar, salt and grain fertilizers pose a threat during transportation and storage. One of the main components of modern-day fertilizers – nitrate – is also used in the manufacture of explosives. This fact should not be overlooked when dealing with fertilizer dust collection. Dust produced during the manufacturing and transportation process of many...

The presence of grain dust in the air poses a significant threat as it can cause damage to equipment, reduce its work time, and injuries to workers. Controlling grain dust is a crucial process and a challenge. The grain dust present in the air can result in an explosion as it is highly combustible; large...

Dust is often a major problem in a lot of different industries: coal dust from the air at loading facilities, asphalt dust during concrete production, heavy iron ore dust at iron mines, sugar dust, etc. The latter is a major nuisance for the sugar industry as it causes a substantial loss in revenue due to...

Acid gases from power plant and boiler combustion, such as sulfur dioxide and hydrogen sulfide, pose a major threat to human health and the environment. The main ways that acid gases deposit themselves is through acid rains and dry deposition. The consequences of acid rains are devastating: the presence of dead or dying plant life...

Venturi wet air scrubber is a pollution control device that utilizes the energy of an incoming gas stream in order to atomize scrubbing liquid. The venturi scrubber is made of 3 parts – a converging section, a throat section, and a diverging section. The gas flow enters the scrubber through the first section, where it gains...

Zinc mining is a process of metal zinc extraction through mining. Zinc metal is produced using the method of extractive metallurgy which consists of the following steps: the metal ore is first finely ground, then it is put through froth flotation to separate minerals from gangue. The last step results in zinc sulfide ore concentrate...

Nitrogen oxides are a group of air-polluting compounds. Only one of these compounds – nitrogen dioxide (NO2) – is monitored as an air pollutant, for the creation of acid rain and its reaction with the ozone.  Nitric acid, which contains NO2, is used in the production of explosives, flour bleaching, and as an oxidizer in...

Concrete is an extremely important part of the infrastructure of modern life and its production is a growing sector of industrial production.Asphalt concrete is used in many different applications, most commonly in the construction of highways and roads. A variety of mixtures can be used to manufacture asphalt concrete, some of which include hot mix,...

The human impact on the environment has been a topic of discussion for the past 50 years. Climatologists predict that as much as two thirds of all Europeans will have their health impacted by extreme changes in weather by 2100. The extreme weather conditions and events are predicted to cause the death of 150000 people...

Of all available air pollution control techniques, wet air scrubbing is considered to be the most cost effective and versatile. Most wet air scrubbing techniques are highly effective and provide 99% treatment quality of both particulate matter and aerosol pollutants. Wet air scrubbers are not only effective but also efficient and often require less energy...
