1. A turbidity and microorganism sensing system in a water treatment system comprising:

  • a filter filtering water flowing through a water flow path;

    a UV light source irradiating water flowing through the water flow path;

    a first light sensor wherein the first light sensor senses the intensity of UV and visible light emitted from the UV light source that radiates through the water flow path;

    a reference light sensor located proximate to the UV light source wherein the reference light sensor senses the intensity of UV and visible light emitted from the UV light source that has not radiated through the water flow path; and

    a microprocessor in communication with the first light sensor and the reference light sensor, and configured such that the differences in sensed UV light intensities are utilized for evaluating microorganism levels, and the differences in sensed visible light intensities are utilized for evaluating turbidity levels in water flowing through the system.
