Abstract:
Provided is a wastewater treatment process using an electrochemical electrode device. The electrochemical electrode device comprises at least one electrochemical electrode (30) comprising an appropriate electrode plate. The process comprises the following steps: causing water containing an undesired solute to pass through at least one electrochemical electrode (30); applying a direct current to the electrochemical electrode (30) to destroy the undesired solute in the water so as to output water having a lower concentration of the undesired solute. The direct current is adjusted via a specific power control procedure. The control procedure at least comprises the following cycle of an applied current sequence: a period of operation with a preset constant current flowing through an electrochemical electrode (30); applying a reverse constant current to reverse positive and negative electrodes while maintaining an absolute magnitude of the constant current; and a period of operation with the constant current flowing through the electrochemical electrode (30).
Abstract:
A system and method for treating flowing water systems with a plasma discharge to remove or control growth of microbiological species. The system and method protect other components of the water system from being damaged by excess energy from the electrohydraulic treatment. The system and method also recycle ozone gas generated by a high voltage generator that powers the plasma discharge to further treat the water. A gas infusion system upstream of or inside a plasma reaction chamber may be used to create fine bubbles of ozone, air, or other gases in the water being treated to aid in plasma generation.
Abstract:
The present invention provides a hydrogen water generator capable of efficiently generating hydrogen with a structure in which anode electrode(s) and cathode electrode(s) are arranged in a container in an approximately vertical direction. The electrode portion 4 which includes two or more of anode electrodes 4A or cathode electrodes 4B is supported by a generator body cover portion 2. The generator body cover portion 2 is held and the electrode portion 4 is immersed in drinking water in a beverage container 12 such as a cup. Then, electrolysis is caused owing to that a controller 11 applies voltage obtained by boosting supply voltage from a battery 8 to the electrode portion 4 for a predetermined time. At this time, since a plurality of energizing paths between the anode electrode(s) and the cathode electrode(s) are formed, hydrogen can be effectively generated in the drinking water.
