    Abstract: A water purification system including a constant current electrical control system for providing a constant electric current between an anode and cathode in contaminated variable resistance water flowing between the anode and cathode, and a filtering system to remove the clustered particles after the water passes between the cathode and anode. The anode is encircled by a cathode screen with a fluid flow pattern between the anode and cathode to aid the function of the constant current system. In the preferred embodiment, the constant electric current between the anode and cathode is provided by an electrical circuit having an adjustable voltage regulator with the output of the regulator connected to the drain of a Field Effect Transistor, F.E.T., and with the control terminal of the voltage regulator connected to the source of the F.E.T. In addition, the source of the F.E.T. is connected to the anode of the device and the gate of the F.E.T. is electrically biased by a resistor bridge between the drain and the source of the F.E.T. so that the F.E.T. is "on" in a saturated mode.

    Abstract: A waste metal extraction apparatus is disclosed which includes a tank (1) having a plurality of oppositely disposed arcuate baffles (14) disposed on the sidewalls. The baffles are placed in an offsetting relation in order to direct the flow of a fluid through the cell in essentially a serpentine fashion. The arcuate baffles facilitate maintaining a maximum velocity through the turning radius of the fluid passing therethrough to prevent a solids buildup. In addition, the tank is placed at an angle of at least 6 degrees downwardly sloped in the direction of flow. The tank bottom (6) includes a plurality of sockets (20) sized to engage a plurality of cathode supports (21) placed therein, with each support including a mating end (22) for mating with the socket. Each post includes a slot (23) extending substantially therethrough for accepting a cathode (13) therein. A conductive metal fork (31) is disposed over the post having legs (32) which extend the length of the cathode, providing uniform electrical properties across the surface of the cathode thereby providing for optimum, uniform metal removal. The tank further includes a sludge gate (36) at the outlet end thereof with the sludge gate provided for removing any solids which settle as the waste stream follows the serpentine path provided by the arcuate baffles, the sludge gate removing a concentrated solids-containing stream which may be filtered and recycled to the tank inlet. In another embodiment, the waste stream flows through flow control baffles, which provide individual flow control by each cathode, to maximize contact and metal removal. Utilizing the combination of flow modifying baffles, a sloped bottom and enhanced electrical contacting means provides for use of electrolytic cells for removing heavy metals from streams containing about 1-15% solids without requiring frequent down time for tank cleaning.

    Abstract: An electrochemical cell has an annular flow passage for electrolyte solution. The cell is designed such that, in an intermediate zone, the passage is of constant cross-section (to achieve high electrolytic activity) and, in end zones, the passage progressively increases in cross-section to a maximum value (to lower the current density in regions in which unwanted deposition of salts may preferentially occur). The cross-sectional shape of the passage along its length also assists in reducing turbulence in the flow thereby reducing the rate of deposition of salts. Owing to the low rate of deposition, it is possible to maintain the electrodes relatively clean by current reversal at relatively infrequent intervals. That enables the cell to be used for longer periods between cleaning operations.

    Abstract: The treater employs a pair of closely spaced, superimposed circular electrode plates, and the liquid to be treated is passed through the limited area between such plates in a pressurized sheet such that the liquid tends to clean the electrodes at the same time as it receives treatment thereby. An annular groove adjacent the discharge periphery of the lower plate has the effect of causing the discharging sheet to assume an umbrella-like configuration to promote aeration of the discharging liquid. If desired, the plates may be associated with a receptacle in such a way that the umbrella-like discharging sheet engages the walls of the receptacle at one electrical polarity while at least one of the electrode plates is of the opposite electrical polarity so as to promote effective treatment. On the other hand, if desired, the plates may be submerged within such a receptacle adjacent the sludge collecting at the bottom thereof. In one embodiment the opposed plates are of the same electrical polarity while another electrode situated upstream from the plates is oppositely charged.
