ABSTRACT:
In spite of the considerable development registered in microbiology, humankind remains incapable to dominate scientifically and technologically the large microbial world. This is well established and illustrated, unfortunately, in the present Coronavirus disease (COVID-19) pandemic. This work aims to contribute to highlighting the world of pathogenic microorganisms, especially viruses, and their removal from potable water. Identical to the manner by which chemical contaminants are handled in the environment, the particular properties that control transport and demobilization of enveloped viruses in solutions, on surfaces, and in the air must be understood. Besides, the fashion by which ecological parameters form likely virus transmission and mutation mechanisms should be comprehended. Since water treatment constitutes a secure barrier against drinking water infection, the main stages in the water treatment plant dealing with pathogens removal such as disinfection have to be enhanced with more efficient techniques such as advanced oxidations processes. In the field of eliminating pathogens, some research trends are suggested especially those founded on thermal destruction and solar irradiation due to their high performance and low costs.
