Abstract: A water treatment device includes: an insulating divider which divides a space inside a water tank into two treatment vessels adjacent to each other in a horizontal direction, and includes a current carrier which is able to energize water in the two treatment vessels; a treatment unit including a pair of electrodes, a power supply, and a power supply controller; a water supplier which supplies water to each of the treatment vessels; and a draining member which drains water from each of the treatment vessels. The treatment unit includes a detector which detects a level of water in each of the treatment vessels based on an index corresponding to a current value between the pair of electrodes.

Abstract: A system combines complete, ultra-thin cells into a monolithic and robust framework necessary for desalination applications which yields orders of magnitude faster desalination. The electrode pairs are located so that a flow of feed water flows through or around the electrode pairs with the flow perpendicular to sequentially applied electric potentials. The system is controlled to charge the series of electrode pairs sequentially or phased. That means the charging of the second electrode pair is delayed with regard to the charging of the first electrode pair and the charging of a third electrode pair is delayed with respect to the charging of the second electrode pair.

Abstract: A side-stream particle precipitator system for the breakdown and removal of organic and inorganic suspended solids in water cooling systems using a plurality of ionizer treatment units utilizing electric and electro-magnetic fields and a mechanical vortex precipitating system with a static mixer for increasing retention time of the water complex in the precipitator to remove particulate materials contained in the water complex as suspended solids. The system also uses high voltage electrodes for charging the water complex to breakdown laminar flow at the conduit walls to mechanically dislodge any build-up of bio-materials or chemical compounds along the walls resulting in an increase in thermal conductivity.

Abstract: Method and Apparatus for Treatment of Aqueous Dispersion A method and apparatus for applying electrocoagulation treatment to an aqueous dispersion includes: flowing the aqueous dispersion through a region with sacrificial electrodes located between opposed electrodes, and applying a voltage across the electrodes to pass a current. The voltage is maintained at a value V max when the conductivity of the aqueous dispersion is S min or less and the voltage is allowed to decrease to values less than V max as the conductivity of the aqueous dispersion increases. Electrolyte may be added to the aqueous dispersion at low conductivities to further reduce power consumption. The invention allows the electrocoagulation process to operate automatically, without operator intervention, over a wide range of particulate levels with reduced electrical power consumption.

Abstract: An electrochemical cell having a cation-conductive ceramic membrane and an acidic anolyte. Generally, the cell includes a catholyte compartment and an anolyte compartment that are separated by a cation-conductive membrane. While the catholyte compartment houses a primary cathode, the anolyte compartment houses an anode and a secondary cathode. In some cases, a current is passed through the electrodes to cause the secondary cathode to evolve hydrogen gas. In other cases, a current is passed between the electrodes to cause the secondary cathode to evolve hydroxyl ions and hydrogen gas. In still other cases, hydrogen peroxide is channeled between the secondary cathode and the membrane to form hydroxyl ions. In yet other cases, the cell includes a diffusion membrane disposed between the secondary cathode and the anode. In each of the aforementioned cases, the cell functions to maintain the pH of a fluid contacting the membrane at an acceptably high level.
