The present disclosure exhibits an electrolyzed ozone water ozone water generator composed of coated titanium anode. An electrolyzed ozone water composed of coated titanium anode includes n anodes and n+1 cathodes, wherein the anodes are coated titanium anodes, and the cathodes are titanium cathodes or stainless-steel cathodes. The coated titanium anode includes a titanium substrate and a tin dioxide coating layer doped with ruthenium and nickel, which is made by etching and drying the titanium substrate roughened by sandblasting, and then evenly spreading the titanium substrate with a tin dioxide coating solution doped with ruthenium and nickel, and drying, and thermally decomposing the coating material. The anode and cathode are immersed in water with a conductivity greater than 30 μs/cm, powered by a constant current, and the power supply voltage ranges from 3.5 to 12V. The water is electrolyzed under the action of an electric field, and the oxygen ions generate ozone microbubbles under the action of the anode catalyst. The ozone microbubbles rapidly dissolve into the water directly generating ozone water. The generator of the present disclosure is environmentally friendly, low cost, simple process operation, and easy to scale production; the generator is easy to replace, convenient to use, simple in structure and low in cost.

A flow-through electrochemical reactor includes a housing having a solution flow-path. A flow-through or solid first electrode is disposed within the solution flow path. A second electrode is spaced apart from the flow-through or solid first electrode, thereby creating an electroactive gap between the flow-through or solid first electrode and the second electrode. The electroactive gap is less than 5 mm and greater than 2 mm.

Apparatus and method for electrolysis of urea is capable of removing urea from waste-water generated by human urine or agricultural run-off while simultaneously producing cleaner water and hydrogen gas.
