Abstract: A fluid treatment module includes a pipe providing a flow channel in which fluid flows, the pipe having an inlet and an outlet, a light source module including a substrate and at least one light emitting diode disposed on an upper surface of the substrate and emitting light into the pipe to treat the fluid, a reflector disposed inside the pipe to reflect the light emitted from the light source module and having higher reflectivity with respect to the light than the pipe, and a heat dissipation plate contacting a rear surface of the substrate to dissipate heat from the light source module. The inlet, the outlet, or both are provided in plural to allow a flow speed and a flow direction of the fluid flowing into the pipe to be controlled, and the heat dissipation plate has higher thermal conductivity than the substrate.
