The gas hydrogen sulfide (H2S) is poisonous, combustible, and colorless. It smells like rotten eggs. It is created organically, by humans, and from natural sources: H2S is frequently found in natural gas and petroleum deposits and is created when organic matter decomposes. Filtration systems are intended to eliminate impurities or undesirable elements from a fluid or gas by passing it through a media that allows the desired components to pass while trapping the undesirable ones. Water treatment, air purification, oil and gas processing, medicines, food and beverage production, and other sectors and applications make use of these systems.
