Ship's sewage consists of "black water" and "greywater" that contain bacteria, viruses, detergents, and microplastic particles. Untreated ship's sewage, which is more concentrated than the land-based wastewater, makes release into the marine environment more alarming. Therefore, sewage disinfection is a crucial challenge for humanity to combat pollution of pathogens and persistent organic pollutants. There is an urgent need for sewage treatment methods that are more efficient and environmentally friendly. Strong oxidizing radicals whose formation is based on photocatalytic technologies are very promising. The paper aims to provide an overview of photocatalytic technologies treating pathogens, including transfer of severe acute receptive syndrome coronavirus 2 (Covid-19) and persistent organic pollutants in ship's greywater.
