Industrial air scrubbers are pollution filtration systems that use solid or liquids to remove gaseous pollutants from a waste stream. Dangerous and caustic chemicals are filtered out of a gas exhaust stream by using this amazing tool known under the name “scrubber”. There are three basic types of industrial scrubbers:   One of the most...

The Environmental Protection Agency (EPA) is constantly in process of adding more and more chemicals under the “prevention of accidental releases” program dealing with releases of extremely hazardous air pollutants. All companies that produce, use or handle more than the threshold quantities with at least one of these substances will be obliged to have an...

A problem with dust emissions from sugar factories is no longer so acute, as it was even a decade ago. One of the main reasons for such positive changes to occur is the increased use of wet air scrubbers for removing dust from boiler flue gas. There are many advantages of the use of a...

Wet air scrubbing is a simple and effective way of exhaust air or gas cleaning and removal of toxic or smelling compounds. In wet air scrubbers, the exhaust gas gets in close contact with fine water droplets or a water mist in a co-current or countercurrent flow. The wet air scrubbing methods are more effective...

Cyanide naturally occurs in nature and is found throughout nature including in fruits, nuts, plants, and insects. Cyanide is used in multiple industries where it is used safely and without harming the environment despite its toxicity. Cyanide is a useful industrial chemical, over one million tons of which are used annually in such applications as...

Airborne coal dust is a byproduct of coal production, and it presents a danger of spontaneous explosion and a respirable dust health hazard. Coal dust consists of small particles, smaller than 75 µm in size, and can easily deposit throughout mine entries and propagate explosions that had been initially fueled by methane gas. As the...

Intensive livestock production is connected with several environmental effects, including emissions of dust and particulate matter. The particulate matter that is emitted from animal houses consists of feather and hair fragments, skin debris, feed particles, mold spores, bacteria, fungus fragments, litter fragments, etc. The size of particulates varies between 0.005 and 100 μm in diameter....

Grain dust is not a harmonious collection of particles; in fact, it included different types and sizes of particles. The dust components vary depending on the type of grain that is being handled, however, grain dust typically consists of grain particles, soil particles including silica, plant material, fungi, bacteria, fertilizer and agricultural chemical residues, insect...

Over the past several years several sugar dust explosions have happened at sugar producing and storing facilities. One of them is an explosion that happened at the sugar silo at Perfetti Van Melle candy factory in Erlanger, Kentucky. The culprit of the explosion is estimated to be the presence of a critical amount of sugar...

Grain dust is an inevitable part of grain transportation and handling; this problem needs to be addressed with the best management practices in order to prevent safety concerns. The dust that occurs during grain handling operations typically consists of grain particles, soil particles, plant material, fungi, bacteria, fertilizer and agricultural chemical residues, insect waste, small...
