Abstract:
The invention provides a device to purify waste water by a two-step procedure containing an electroflotation unit and an electrical dis-infection unit integrated into the same overall construction. Characteristic to the construction is that the said two units have a common anode and two individual cathodes which can be in different potentials in respect to the common anode.

Claim (Index 1):
A purification and disinfection device to purify waste water by a two-step procedure, said device having an electroflotation unit, and an electrical disinfection unit integrated into same construction, wherein:\n i) the device contains at least three ohmically isolated electrically conductive tubes, said tubes being a central rod (C), an inner tube (I) and an outer tube (O) organized concentrically so that a space containing the central rod (C) inside the inner tube (I) forms the electroflotation unit and a space between the inner tube (I) and the outer tube (O) forms disinfection unit; ii) lower ends of the tubes are sealed but contain entrance of waste water into the electroflotation unit; iii) lower end of the outer tube (O) contains opening for outlet of purified and disinfected waste water; iv) upper ends of tubes contain outlets for electrolysis gases and froth and overflow of water from the electroflotation unit to the disinfection unit in which flow of water goes from up to down to effect concentrating electrolytically achieved disinfecting gases; v) the outer tube (O), the central rod (C), and the inner tube (I) function as electrodes for effecting electroflotation and electrical disinfection of waste water; vi) the inner tube (I) functions as an anode, and the central rod (C) and the outer tube (O) function as cathodes which are not, however, necessarily in the same electrical potential in the respect to inner tube (I); vii) the electrodes formed of the inner tube (I) and central rod (C), and the electrodes formed of the inner tube (I) and the outer tube (O) are pair-wisely electrically connected to an adjustable DC power supply, or or pair-wisely connected to two separately adjustable DC power supplies; and viii) the construction and materials of the device allow temporary changing of polarity without invalidating of normal function of the device.
