Abstract: A fluid decontamination apparatus is provided having a container body with a plurality of three-dimensional open structure (3DOS) substrates spaced about therein, wherein a contaminated fluid flowing through the container body will contact the 3DOS substrates. Nozzles can be inserted and secured within inlet apertures disposed about the container body, configured to inject the contaminated fluid with/without air to induce the occurrence of hydrodynamic cavitation. The substrates can be porous and permeable enabling the contaminated fluid to flow therethrough, wherein the fluid flow passageway through the pores extends the volume of contaminated fluid exposed to turbulent and cavitation inducing flow conditions. Moreover, the 3DOS substrates may be coated with one or more types of catalysts so as to initiate chemical reactions. As such, the extended exposure of the contaminated fluid to hydrodynamic cavitation forming conditions, along with the chemical reactions carried out on the porous surfaces, enable an increased number of toxic species and unwanted organic compounds to be destroyed and/or altered, thereby enhancing the decontamination of the flowing fluid.

Abstract: A device for recycling sulfuric acid is provided. A container has an inner space. An inlet is located on the first side of the container for introducing a liquid containing sulfuric acid and hydrogen peroxide through a pump. An outlet is located on the second side of the container for exhausting the treated liquid from the container, and the first side and the second side are opposite sides. IR lamp and UV lamp are located in the inner space of the container for making contact with the liquid. IR radiation emitted from the IR lamp and UV radiation emitted from the UV lamp decompose the hydrogen peroxide in the liquid to water and oxygen. The IR radiation heats the liquid to 90° C. to 130° C., and the oxygen is exhausted through the air hole.
