A space optimized ultra violet germicidal irradiation system

A UV-germicidal irradiation system for treatment of liquids, wherein the UV-germicidal irradiation system comprises:

• outer flanks comprising a top flank a bottom flank a first side flank, a second side flank, a third side flank, and a fourth side flank;
• a plurality of tubes, each of the plurality of tubes comprising an inlet section, a coil section, and an outlet section, wherein the coil section is a spiral-shaped tube creating a coiled fluidic pathway extending along a longitudinal axis (L) of the coil section in a horizontal plane from the inlet section to the outlet section;
• wherein for each of the plurality of tubes the inlet section comprises a tube inlet through which a liquid enters the tube and the outlet section comprises a tube outlet through which the liquid exits a corresponding one of the plurality of tubes;
• wherein for each of the plurality of tubes, the outlet section extends in parallel with the longitudinal axis (L) of the coil section such that the tube inlet and the tube outlet are positioned on the first side flank of the UV-germicidal irradiation system (10);
• for each coiled fluidic pathway of each spiral-shaped tube, one or more light sources are configured to illuminate the coiled fluidic pathway of the spiral-shaped tube wherein the one or more light sources emit light with at least one wavelength within a wavelength range between 180 nm and 315 nm;
• and
• a mounting frame comprising a plurality of openings including a plurality of light source receiving openings in which the one or more light sources are removable mounted, wherein the plurality of light source receiving openings are accessible on the first side flank of the UV-germicidal irradiation system
