Abstract: A method of controlling a chemical reaction is disclosed. The method may include feeding a solution at a first flow rate into a reactor and detecting a sound in the reactor using a sound sensor that is adjacent to the reactor. The sound sensor may convert the sound into a sound signal. After the sound signal is acquired, it is compared to a stored sound signal or a stored sound threshold to detect a reaction event. The method may include adjusting the flow rate of solutions into the reactor in response to the reaction event.

Abstract: A method of analyzing water in a continuous casting process and controlling chemical addition to the water may involve measuring, with a plurality of sensors, at least one characteristic of a water in a plurality of different locations of a water recycle system for the continuous casting process. The continuous casting process can have multiple spray nozzles that spray water on a metal being cast, and the water recycle system may include a gravity settling tank, a filter, and a cooling tower. A processor can determine, using the measured at least one characteristic of the water from the plurality of sensors, a composite water quality value for the water in the water recycle system. A chemical additive can be controllably added into the water recycle system based on the determine composite water quality value.

Abstract: A method of producing chlorine dioxide is disclosed. The method may include feeding a reaction mixture into a separator. The reaction mixture may follow a helical path through the separator and produce gaseous chlorine dioxide within the separator. Gaseous chlorine dioxide may be withdrawn from the separator and used to disinfect process water.

Abstract: The present disclosure generally relates to methods of treating process water using a reactor for generating chlorine dioxide onsite. The onsite generation system may include double ensured precursor feeding, effective reactor, automated control/alarm, and effective product delivery. The reactor may include a mixing device, a first feed line connected to the mixing device, and a second feed line connected to the mixing device. The reactor may include a proximal portion in fluid communication with the mixing device and a distal portion in fluid communication with a motive water line. The mixing device, the reactor, a portion of the first feed line, and a portion of the second feed line may be positioned within the motive water line.
