The present document relates to systems that employ photoelectrocatalysis, as well as methods using photoclectrocatalysis. In particular, the systems and methods can provide improved removal of contaminants from water.

An electrode and a method of forming an electrode, the electrode being formed from boron doped diamond, the electrode having a total solution accessible electrode area comprising at least 60% diamond stabilised non-diamond carbon. There is also disclosed an electrochemical cell the electrode.

A method of treating a quantity of water that includes a first level of a contaminant and is discharged from a process includes mixing the water with an effluent having a second level of the contaminant to produce a condensate having a third level of contaminant, the second level being greater than the first level. The method further includes passing the condensate through a reverse osmosis system to produce a permeate having a fourth level of the contaminant and a concentrate having a fifth level of the contaminant that is greater than the fourth level. The method also includes oxidizing the concentrate in an electro-oxidation system to generate the effluent and directing the effluent to a point upstream of the reverse osmosis system to perform the mixing step.

An electrolysis electrode and a preparation method therefor, an electrolysis apparatus, and a clothing treatment device. The electrolysis electrode includes a substrate, a transition layer, and an electrode catalytic material layer, and the transition layer is attached to the surface of the substrate, the electrode catalytic material layer is attached to the surface of the transition layer, and the thickness of the transition layer satisfies that: electrons can pass through the transition layer. The transition layer of the electrolysis electrode is relatively thin, so that electrons can pass through the transition layer due to a quantum tunneling effect, and thus the electrocatalytic performance of the electrolysis electrode is basically not affected. Furthermore, the transition layer plays the role of transition connection, and can greatly improve the phenomenon of cracks in the electrode catalytic material layer.

Systems and methods for treating contaminated water as a source for hydrogen is disclosed herein. A hydrogen-gas-containing gaseous byproduct from treating contaminated water is collected, and gases other than hydrogen are removed therefrom to form a hydrogen-rich gaseous product. The hydrogen-rich gaseous product may then be used as fuel to power the contaminated water treatment step.

The present invention relates to system and method for lowering the pollutants in waste water and electro transformation of waste waters and other reactants. A unique flow-through system is introduced where separate streams of oxidants and reductants can be introduced in the electrolysis chamber (100) and do not mix too much due to the laminar flow. The by-products can be easily separated from the outlets from both the anodic (101) and the cathodic chambers (102) by a cost-effective separator and the gases can be introduced back into the electrosynthesis chambers as required to break-down the pollutants.

A cleaning device including a disinfection water supply portion to supply cleaning water with a dissolved disinfection component, and a bubble generation portion to contain bubbles into the cleaning water on a downstream side of the disinfection water supply portion.

An electrolytic reactor for the electrolytic treatment of a fluid is disclosed. The reactor comprises an electrolytic chamber, an electrode cartridge comprising an electrode assembly longitudinally extending from a crown section configured to operatively seal the electrolytic chamber when the electrode assembly is inserted in the electrolytic chamber; an inlet extending perpendicularly to a vertical longitudinal axis defined by the electrolytic chamber; and an outlet extending through the crown section along the vertical longitudinal axis defined by the electrolytic chamber, the outlet being configured to be in fluid communication with the electrolytic chamber when the electrolytic chamber is sealed by the crown section. Advantageously, by having the outlet extending upwardly above the electrodes, any dead zone typically found on electrodes at the level of the outlet are eliminated, increasing as such the useful surface area of the electrodes spanning the entire length of the electrolytic chamber.

A faucet for dispensing a fluid includes a spout, a pull-out spray head removably coupled to the spout and including an outlet, and a valve assembly in fluid communication with the outlet. Additionally, the faucet includes a fluid treatment assembly configured to output a treatment into the fluid.

Example methods and systems for segregation and treatment of waste water streams for enhanced oil recovery are disclosed. One example method includes generating concentrated solution by treating, using a forward osmosis process, waste water of one or more gas streams from a gas plant associated with one or more gas wells, where draw solution of the forward osmosis process includes produced water from one or more crude oil production traps, and the waste water contains kinetic hydrate inhibitor (KHI). The concentrated solution is treated using an oxidation process to generate oxidized solution by decomposing the KHI in the waste water. The oxidized solution is injected into an oil reservoir through a water injection well for enhanced oil recovery.
