Study of the Microbiological Parameters of Irradiated Samples at Hovsan Coastal Area of the Caspian SEA

Abstract

Biological organisms can threaten water quality and cause waterborne diseases. Because testing for each pathogenic organism is very expensive and time consuming, coliform bacteria and E. coli from environmental and animal sources serve as good pathogen indicator organisms. This study focused on the evaluation of water quality in microbiologically purified waste from the tap and Hovsan coastal areas of the Caspian Sea via gamma-ray monitoring. Radiation technology allows for the possibility of combined water purification, including chemical and biological treatment; therefore, this technology is more suitable for water disposal. Before irradiation, the concentrations of total microbes (at 22°C and 37°C), E. coli, heterotrophic bacteria and total coliform bacteria were monitored. The samples were then irradiated with different doses of gamma radiation. In this context, the application of gamma radiation for the microbiological treatment of wastewater, domestic tap water and water from the Hovsan coastal area of the Caspian Sea, which can be applied to minimize the effect on the human body, was investigated.
