A bubble generator for generating gas bubbles for a flotation vessel, the bubble generator including at least one inlet through which a water stream can enter the 5 bubble generator; at least one pair of electrodes capable of electrically decomposing water to create gas bubbles; and at least one outlet through which water entrained with gas bubbles can exit the bubble generator. In use, at least one of the outlets is in fluid communication with a flotation vessel containing waste water including contaminants, the gas bubbles being used to separate at least a portion of the 10 contaminants from the waste water in the flotation vessel.
