Recent data demonstrated a gigantic role of aquatic organisms in making water clean and clear. It was shown in the long-term international project that was carried out recently. The amazing results were presented in this paper, which is a review of the multi-year studies of aquatic organisms, mainly marine and freshwater invertebrates that are filter-feeders – freshwater mussels, marine mussels, oysters. They play a key role as biological filters – as an important part of the biosphere and hydrosphere. The studies were conducted in laboratories of four countries, including U.K. (England), Russia, Ukraine.
