Highly effective and low cost ozone compact electrochemical generator for environmentally friendly disinfecting (OCEGE)

Objetivo

Ozone is the second most powerful oxidant after fluorine. It is widely used to supplement or replace chlorine in a variety of processes including water treatment, treatment and improvement of the quality of indoor air, plant growth, preservation of fruits and vegetables, etching and cleaning semiconductors, textiles, paper, etc. In addition, ozone leaves no residue after disinfection, as opposed to chlorIne that leaves toxic and environmental and human harmful substances. Current commercial methods for obtaining ozone are mainly based on the generation of a plasma corona through which air is driven, yielding a little ozone concentration of around 3%wt in the resulting gas stream. Other methods for producing ozone are UV bombarding of oxygen -yielding around 0,1 %wt of ozone-, and electrochemical ozone generators -producing higher concentrations, but with the penalty of an enormous power consumption related to the evolution of by-product hydrogen in the electrolysis of water. The proposed system is based on an electrochemical cell, which produces a mixture of oxygen and ozone in an adjustable ratio, and a hydrogen peroxide stream. The final device should meet the following operational targets: Development of a noiseless electrochemical ozone generator using purified water and electrical energy to produce an adjustable ozone/oxygen stream (with up to 18%wt of ozone) and an ozone production rate of up to 20 g/h. To maximise energy efficiency, with an electrical power requirement of less than 2 kW, by depolarising the cell with oxygen at the cathode and thus producing hydrogen peroxide. Costs of manufacture to enable a market price between 8k and lOk. The resulting device must be compact, versatile, and easy to maintain to facilitate its use in the many applications where ozone and hydrogen peroxide are required. The social impact of this proposed project will lie in the integration of a group of European SMEs into a consortium, whose aim will be to
