  • Patent number: 10758842
    Abstract: Multiple site purification can be achieved by a small plastic portable voltaic inspissation unit in a box configuration. Each unit may feature an air hopper, a recirculation line, a gas diffuser, a centrifuge, a decanter, and multiple anodic and cathodic voltaic inspissation plates that may direct fluid through a box in a meandering or serpentine fashion. Multiple devices may be present or omitted, and retention times may be varied both by the presence or absence of recirculation and the flow rate accomplished by use of different metal in the plates depending on purification goals. Air may be injected interstitially prior to passage into the box to aid in purification, and ultimately both ease of transport and substantially improved purification percentages may be achieved relative to prior systems.

Within the vessel is at least one submerged electric arc between a pair of electrodes (e.g. carbon based electrodes) powered by either a DC or AC current. The electric arc produces a combustible gas as the liquid is pumped through a bore in one or both of the electrodes, delivering the liquid directly to the location of the arc, thereby reducing or eliminating any ignition of the gas by the arc. Should ignition occur, at least one vent in the electrode(s) or electrode holder(s) vents pressure from within the bore to the vessel area outside of the electrode(s).

  • Patent number: 8945357
    Abstract: An apparatus (20) for treating contaminated water has an electrocoagulation reactor (26) and a clarifier (30) to receive the effluent of the reactor. The reactor has a reaction vessel (48) having an inlet (58) and an outlet (62), a sacrificial anode (64), a rotatable cathode (68) and a non-sacrificial anode (66). A first gap (70) between the sacrificial anode and the cathode comprises a first water treatment zone. A second gap (74) between the cathode and the non-sacrificial anode comprises the second water treatment zone. The water flow path is from the inlet to the first treatment zone, then to the second treatment zone and then to the outlet. In the clarifier, the reactor effluent is separated into cleaned water and the contaminated sludge.

  • Patent number: 8945353
    Abstract: An apparatus and method for electrolytically treating water which can include the influent inlet arrangements for cavitation and one or more pairs of electrodes. The electrodes can be suitable for a continuous anodic and cathodic operation for treating water. The pressurized influent premixed with oxidant gas, such as, but not limited to, Ozone or Oxygen can be pumped into the reactor vessel through the mixing nozzles preferably arranged radially along the circumference. A power source for each reactor provides voltage and current to the electrodes. The controller maintains the voltage and current to the electrode. The duration of each voltage polarity applied to each electrode can be preferably the same. The polarity of the voltage to the electrode can be periodically reversed at a set interval.
