The IFF "Water, Sea, Oceans" is a competitive festival of documentary films on this theme. Its aim is to present and reward film works dealing with the world of fresh and salt water, to stimulate their production on an international scale and to broaden people's knowledge and interest in the issues of protection of this area of the environment and the world around them, whether underwater, on the surface, on the banks of watercourses and lakes or in coastal areas around the planet. This year, we have become a general partner of the festival. As part of our company's presentation, we demonstrated a mobile water treatment plant. Guests were able to taste treated water from a nearby pond, which met with a great response.
