Environmental and Chemical Processes Questions
What is the term used to describe the process of removing organic matter from water?
-
Ozonation
-
Filtration
-
Disinfection
-
Activated carbon adsorption
D
Correct answer
Explanation
Activated carbon adsorption is a common method for removing organic matter from water. It involves passing water through activated carbon, which is a highly porous material that adsorbs organic compounds onto its surface.
What is the process of converting organic matter into biogas called?
-
Composting
-
Anaerobic digestion
-
Incineration
-
Pyrolysis
B
Correct answer
Explanation
Anaerobic digestion is the process of converting organic matter into biogas in the absence of oxygen. This process is carried out by microorganisms, such as bacteria and archaea, which break down the organic matter into simpler compounds, including methane and carbon dioxide.
