Why is The field of Microbiology important? Microbiology is the scientific study of microorganisms, those being unicellular, multicellular, or cellular. Water microbiology is the scientific discipline that is concerned with the study of all biological aspects of the microorganisms (bacteria, archaea, viruses, fungi, parasites, and protozoa) that exist in water. This is also known as marine microbiology, which is a sub-discipline of environmental microbiology. Wastewater Microbiology focuses on microbial contaminants found in wastewater, methods of detection for these contaminants, and methods of the cleansing water of microbial contamination. Water can support the growth of many types of microorganisms. This can be advantageous. The growth of some bacteria in contaminated water can help digest the poisons from the water. The goal of biological wastewater treatment is to produce an environment in which microorganisms consume the maximum amount of organic substrate and produce clear effluent water. To do this microorganism must convert soluble organic pollutants (BOD) into insoluble biomass (microorganisms) which can be separated.
