ASSEMBLY COMPRISING AT LEAST TWO ELEMENTS IN A MOVABLE ARRANGEMENT RELATIVE TO EACH OTHER AND PREVENTING A BIOLOGICAL FOULING SYSTEM Russian patent published in 2021 - IPC B63B59/04 B08B17/02 

FIELD: filtration.

SUBSTANCE: filter assembly comprising at least two elements in a movable arrangement relative to each other for performing a first function of the assembly and preventing the biological fouling system for exposing at least the area of the assembly to at least partially exposed to water for at least part of its service life, preventing biological fouling as an additional function of the assembly, different from the first function of the assembly, wherein one of the elements is a female element, having inner space, wherein other of elements is male element extending at least partially through inner space of female element, and wherein the area subjected to a biological protection against fouling, comprises at least a portion of the surface of the female member, characterized in that the biological fouling protection system comprises one or more light sources for emitting a biological fouler, wherein the biological fouling protection system is configured to implement coverage of the area with anti-fouling light based on the movable location of said at least two elements relative to each other for performing the first function of the assembly.

EFFECT: technical result is protection of surfaces from biological fouling.
