Abstract (en)

A self-cleaning fountain includes: a structure (770) having two ends, defining a first flow way for a first fluid to flow along, wherein the structure (770) defines holes (772) for allowing a second fluid to flow through the holes (772); a pump system (814) configured to pump the first fluid to a first end of the structure (770); a distributer (904) located at the first end of the structure (770) and configured to spray the first fluid received from the pump system (814) onto the structure (770); a catch basin located at a second end of the structure (770) for collecting the first fluid that has moved along the flow way to the catch basin; a photocatalytic coating (900) on the structure (7770); and a light source (890) configured to direct light on the photocatalytic coating (900).
