  • Publication number: 20240092666
    Abstract: A system for wastewater treatment comprises a membrane filtration device which receives the stream of pre-treated wastewater stream from the pre-treatment unit and generates a reject stream which is supplied to an electrochemical oxidation reactor which generates a reactor effluent stream which is divided into a recirculated wastewater stream that is recycled back to the equalization tank and a reactor discharge stream that is discarded from the system. The target fraction ratio between the volume of the recirculated wastewater stream and the volume of the reactor discharge stream is controlled based on the target total dissolved solids amount in the wastewater to be treated, on the amount of regulated organic substances in the wastewater which are treated by the electrochemical oxidation reactor to increase the efficiency of the electrochemical oxidation reactor to a target value and on the composition of the wastewater being discharged from the system.

  • Publication number: 20230314317
    Abstract: A method for material classification of an object. The method contains the steps of measuring, by a first light sensor, an intensity of a first light signal from an object; measuring, by a second light sensor, an intensity of a second light signal from the object; inputting features related to the intensity of the first light signal and features related to the intensity of the second light signal into a neural network; calculating by the neural network, for each of a plurality of possible classes of material, a probability of the object containing the material of the class; and determining a material of the object based on one of the plurality of possible classes of material that has a highest probability. Embodiments of the invention provide an automatic solution of material classification based on neural network, which achieves a high successful recognition rate of the material.
