Venturi wet air scrubber is a pollution control device that utilizes the energy of an incoming gas stream 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 velocity; the...

Zinc Production and Sulfuric Acid: Risks and Management
Zinc mining involves the extraction of the metal zinc through mining activities. 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...
Wet Scrubbing Solutions for Nitrogen Oxide Reduction
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...
Wet Air Scrubbers for Sustainable Asphalt Concrete Production
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...
Wet Air Scrubbers: A Key Solution for Air Pollution Control
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 150.000 people annually....
Wet Air Scrubbing: The Most Cost-Effective and Versatile Solution
Among all existing air pollution control methods, wet air scrubbing is viewed as the most economical and adaptable. 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 than other...
Effective Dust Control with Wet Air Scrubbers
Wet air scrubbing is often overlooked as a method of air pollution control. The wet air scrubbing technology is not prioritized by engineers for emission control equipment because of their hesitance to switch from the familiar dry dust collectors. However, wet air scrubbers are successfully installed downstream of furnaces, dryers, mixers, bucket elevators, and other...
The Efficiency and Reliability of Wet Air Scrubber Treatment
The treatment quality of an air scrubber refers to the general percentage of a pollutant that the scrubber can remove. In simpler terms, this metric indicates the efficiency of the scrubber operation. The treatment quality of a scrubber is often measured by interference with particle and gas pollutants, as some air scrubbers may be far...
Efficient Sulfuric Acid Vapor Absorption with Wet Air Scrubbers
Sulfuric acid vapor is one of the main pollutants that occur during zinc production. Sulfuric acid vapors do not exist as vapors; instead, they manifest as a fine mist or aerosol in the workplace atmosphere due to their low vapor pressure and hygroscopic characteristics. The mist mainly originates from the electrolyte that consists of a...
Effective Iron Ore Dust Control with Wet Air Scrubbers
Heavy iron ore dust is a result of iron ore mining. Iron ore contains high quantities of hematite or magnetite, but also other elements that are often present in trace amounts. Such elements include silicon, phosphorus, aluminum, and sulfur. The iron ore itself is not harmful, however, the dust that is produced during transportation of...
