    摘要: A submersible system and method for measuring the gas volume fraction in an aerated fluid inside a reactor (1) wherein the aerated fluid comprises a gas dispersed in the form of bubbles in a fluid in the form of a solution, suspension, mixture of liquids or a combination thereof. The submersible system comprises: an open and pass-through gas exclusion device (20) of a variable cross section wherein the inlet opening whereby the fluid enters without gas bubbles towards the opened and through gas bubbles exclusion device (20) is greater than the outlet opening whereby the fluid exits without gas bubbles of the opened and through gas bubble exclusion device (20). The outlet opening abuts with an inlet pipe (23). A chamber (24) which can provide a sealed camera, can contain at least one flow meter to measure the gas-free fluid velocity when circulating between an inlet (27) and an outlet (28) of the chamber (24) or sealed camera The inlet (27) of the chamber (24) or sealed camera can be coupled to the inlet pipe (23). The outlet (28) of the chamber (24) or sealed camera can be coupled to an outlet pipe (26) of the liquid dispersion towards the reactor (1). A flow transmitter (29) connected to the flow meter, located inside or outside said chamber (24) or sealed camera, generates an outlet signal proportional to the bubbles-free fluid velocity through a gas bubble exclusion device and a calculation unit (30) which generates an output signal (31) proportional to the gas volume fraction in the aerated fluid.

    摘要: The invention relates to a system for communication by means of visible light and to the corresponding method, where a channel for transmitting visible light has abnormal conditions, for example, in tunnels of an underground mine with a high degree of dust concentration in the atmosphere and also in rural and urban tunnels in which the fumes generated by an accident produce high concentrations of powdery material in the transmission channel. This problem is solved by using in the system a transceiver for transmitting visible light, a means for receiving visible light, and a Deep Neural Network (DNN), with a specific arrangement, proximity or distance, of ceiling-mounted transceivers formed by LEDs lamps (arrangement of the plurality of LEDs) and Digital Single Lens Reflex (D-SLR) transceivers (formed by reflex cameras in which the lens that forms the image also provides the image in the viewfinder). According to the invention, together all the elements forming the system allowing channel noise to be removed, being able to transmit using visible light with diversity, even if the channel appears interrupted to the human eye.

    摘要: Procedure using zeolite, clinoptilolite type in an upflow anaerobic reactor and sludge blanket (UASBs) in order to obtain granular active sludge, thereby improving the density of the sludge, and thereby, their settling properties, and increase of biomass within reactor by immobilizing microorganisms, to achieve an increase in the efficiency of the removal of organic material and the production of biogas (60-70% methane) in more than 20% over the same type reactor used so far without zeolite, enabling the use of such reactor for treating wastewater with a high concentration of proteins, amino acids and other nitrogen compounds and which prevents the accumulation of nitrogen, which is toxic to the process by allowing zeolite-clinoptilolite, the exchange with alkali and alkaline earth found in specific points of the crystal structure of clinoptilolite by ammonia nitrogen, and also preventing the development of filamentous bacteria, which are difficult to hold up within the reactor and reduces its efficiency.
