A bi-polar electrode having ion exchange polymers on opposite faces of a porous substrate is formed using a method that includes providing an electrode substrate with activated carbon layers on opposite faces of the electrode substrate, wherein said faces have an outer perimeter band void of the activated carbon layers. Gaskets are placed against the outer perimeter band of the electrode substrate void of activated carbon and the electrode substrate is clamped between two rigid plates to form a first airtight chamber on one side of the electrode substrate and a second airtight chamber on the opposite side of the electrode substrate. A first polymerizable monomer mixture having an anion exchange group is added into the first chamber and a second polymerizable monomer mixture having a cation exchange group is added into the second chamber. The first and second polymerizable monomer mixtures are then polymerized in an oven.

A method of water treatment comprising: providing an electrolysis device comprising an electrolysis vessel; providing feed streams to the first salt water chamber of the vessel, second salt water chamber of the vessel, acidic chamber of the vessel, and alkalic chamber of the vessel, the acidic chamber producing an acidic solution and the alkalic chamber producing an alkalic solution; directing at least a portion of the contents of the first and second salt water chambers into a precipitation tank; directing at least a portion of the alkalic solution into the precipitation tank, thereby increasing the pH in the precipitation tank to produce precipitate; and removing the precipitate from the precipitation tank.
摘要:
A bi-polar electrode having ion exchange polymers on opposite faces of a porous substrate is formed using a method that includes providing an electrode substrate with activated carbon layers on opposite faces of the electrode substrate, wherein said faces have an outer perimeter band void of the activated carbon layers. The electrode substrate is placed in a thermoplastic envelope formed by a pair of polyethylene films. A Mylar sheet is placed in each side of the envelope against the electrode substrate, and the envelope is thermally sealed to the outer perimeter band of the electrode substrate void of activated carbon to form a first pocket on one side of the electrode substrate and a second pocket on the opposite side of the electrode substrate. The method also includes inserting a first polymerizable monomer mixture having an anion exchange group into the first pocket of the envelope and inserting a second polymerizable monomer mixture having a cation exchange group into the second pocket of the envelope. The first and second polymerizable monomers mixtures are then polymerized in an oven.
摘要:
A dishwashing apparatus and a methodology are provided for washing dishware using electrolyzed water to provide alkaline and acidic water for wash and rinse cycles. The water used at the beginning of a pre-wash stage is repeatedly used in plural pre-wash cycles and filtered through sediment and oil filtration between pre-wash cycles. Water from a final rinse cycle is saved for use for future pre-wash cycles. The sediment and oil filtration filter are reversely flushed to regenerate the filtration systems.
