Abstract
A device for treating a process fluid contained within a closed chamber with a chemical reactant including a compartment for containing the chemical reactant and a port for allowing flow of the process fluid therethrough. The device is characterized by a recirculation mechanism, such as a piston, for alternately drawing a portion of the process fluid into the compartment through the port to bring the portion of the process fluid into direct contact with the chemical reactant and dissolve and/or react a portion of the chemical reactant into the portion of the process fluid and then forcing the portion of the process fluid out of the compartment through the port to circulate the dissolved chemical reactant throughout the remaining process fluid within the closed chamber. A method of treating the process fluid is also disclosed and includes the steps of disposing a portion of the device below the surface of the process fluid so that the port of the device is within the process fluid. The method is characterized by the step of recirculating the process fluid through the device by alternately drawing a portion of the process fluid into the compartment through the port to bring the porti…
