According to an embodiment of the present disclosure, provided is an optical detection system for detecting a laser speckle generated by multiple scattering of a wave irradiated toward a sample from a wave source, and based on a change in the laser speckle over time, detecting the presence of microbes in the sample in real time.

Clean, safe and efficient methods, systems, and processes for utilizing thermolysis methods to processes to convert various e-waste sources into Clean Fuel Gas and Char source are disclosed. The invention processes e-waste sources, such as for example whole circuit boards, to effectively shred and/or grind the waste source, and then process using thermolysis methods to destroy and/or separate halogen and other dangerous components to provide a Clean Fuel Gas and Char source, along with the ability to recover precious metals and other valuable components from the Char.

The invention relates to an electrochemical reactor for continuous copper electrodeposition at high current densities with copper sulfate electrolytes, which comprises devices and systems of functional means that are linked and operated in line, thereby forming a triad, for standardising operational conditions in a series of operative parallel reactors. The triad, installed in each existing or new electrolytic container, comprises: a gentle electrolyte agitation system (AGSEL) with means for pulsing control of the aeration volume diffused by bubbling directed into each inter-cathodic space; a duo of systems linked in line, which comprises a system of removable anode covers (CAR) for containing, confining and coalescing the acid mist; and an acid mist recycling system (SIRENA) that captures non-coalesced electrolyte aerosols and condenses the steam, returning same to the process, while the pollutants of the gaseous fluid from the reactor are substantially diluted.

A heat exchange device effectively collects heat in a device, in which high temperature occurs, such as a scrubber. The heat exchange device includes a first heat exchange unit having a reactor positioned on the center thereof and having a first passage, which is arranged to enclose the reactor and discharges a first gas generated in the reactor, and a second passage, which is arranged adjacent to the first passage and introduces a second gas introduced from the outside. A second heat exchange unit is installed to enclose the first heat exchange unit and having a third passage, which is connected to the first passage and receives the first gas from the first passage to discharge the first gas to the outside, and a fourth passage, which is arranged adjacent to the third passage and introduces the second gas introduced from the outside into the second passage.

A filtering module includes a cyclone having a contaminated air inlet part into which external contaminated air and cleaning water cleaning the contaminated air are each introduced, and a cleaned air outlet part through which air cleaned by bringing the cleaning water into contact with the contaminated air is discharged; a water tank coupled to the cyclone, to which the cleaning water cleaning the contaminated air is introduced, and storing mixed water in which a pre-stored fluid and the cleaning water are mixed; and a fluid circulating part providing the mixed water stored in the water tank to the contaminated air inlet part.
