Waste water is purified by means of the flotation process by using aluminum having on at least one surface thereof an amalgam of aluminum and mercury. The hydrogen gas and aluminum produced during the reaction between the waste water and the aluminum amalgam is used to float the impurities to the surface of the waste water being treated, the impurities then being removed and the purified water recovered. Flotation apparatus for carrying out the process is also described.

A tank, having a height several times its effective diameter, has a plurality of horizontal electrodes disposed throughout its entire height. Conduits and controls are provided for downflow of liquid to be purified in a non-turbulent manner. Electrolysis of the liquid causes gas bubbles to flow upwardly. This apparatus creates a non-turbulent flow of liquid directly counter to the flow of gas bubbles for a substantial vertical distance. In one embodiment the tank is a cylinder, while in another it has downwardly converging sides. A third embodiment shows two compartments arranged for sequential flow of liquid therethrough.

In a flotation method for purification of industrial or municipal waste water, in which the waste water comes in contact with electrodes having an electrical potential capable of electrolytically decomposing a portion of the waste water, thereby creating an ascending stream of gas bubbles, the waste water is mixed before or during the electrolytic decomposition with wettable particles of polymer material which are practically insoluble in water and have an absolute density of 1.3 g/cm3 at the most. Polymeric materials, especially polyalkane fibrids, are suitable for use as particles. This process makes it possible to purify oil-containing waste water by electroflotation without forming an oil film on the electrodes. | ||||||

An electroflotation apparatus for removing impurities from waste water is disclosed. The apparatus comprises an electrolytic cell for treating the waste water and generating a flock containing the impurities as well as an outlet pipe having a linear central axis located co-axially with the electrolytic cell for passing the water and flock from the electrolytic cell to a separation area. The outlet pipe comprises a first end connected to the electrolytic cell and having a first diameter, as well as a second end through which the treated water and flock exit the outlet pipe, the second end having a second diameter. A length extends between the first diameter and the second diameter. The ratio of the second diameter to the first diameter is between 1.5:1 and 6:1. The ratio of the length to the first diameter is between 7:1 and 45:1. The outlet pipe reduces the turbulence of the treated water from the electrolytic cell before the treated water is passed to the separation area such that aggregation of the flock in the separation area is increased. | ||||||

A method and apparatus for separating impurities from a liquid stream includes a feed tank for containing an untreated liquid, a mixer for generating and mixing bubbles throughout the wastewater, and a settling tank for allowing the wastewater to settle for removal of impurities through dissolved gas floatation. The mixer includes a housing and a rotor rotatably mounted within the housing. The rotor is electrically isolated and the peripheral wall of the housing is electrically isolated and the rotor preferably has bores formed in its peripheral surface to produce cavitation to aid in mixing of fluid within the mixer. A power supply is coupled to establish a relatively positive electrical charge on the rotor and a relatively negative electrical charge on the wall of the housing. The charge causes electrolysis to occur within the fluid, which forms small low surface tension gas bubbles on the rotor and housing wall. These bubbles detach and are mixed with the fluid, where they can attach to and separate impurities through dissolved gas floatation. | ||||||
