Abstract: There is described a process for treatment of a fluid comprising an oxidizable contaminant. The process comprises the step of contacting the wastewater with a combination of: (i) a sulfide, (ii) a complex of Fe(III) and a chelating agent, and (iii) an oxidant. It has been discovered that of treatment of a fluid containing an oxidizable contaminant employing iron(III)-chelates as the Fenton catalyst may be significantly improved by including a sulfide in the reaction scheme. As described herein, by employing sulfide ion, the present inventors have been able to: (i) increase the rate of iron recycling from minutes or hours to a few seconds, and (ii) destroy benzene in an oil and gas refinery (OGR) wastewater in less than one minute. It is believed that these findings in OGR wastewater can be extended to other fluids containing other oxidizable contaminants.

Abstract: There is described a method of determining the UV fluence received by a fluid. The method comprises the steps of: (a) irradiating the fluid at an unknown UV fluence; (b) measuring the fluorescence of a test sample of the fluid after irradiation in Step (a) to produce a test signal proportional to the concentration of a prescribed fluorescent composition of matter comprised in the test sample; and (c) determining the value of the unknown UV fluence by comparing the test signal to a calibration curve of a control signal proportional to concentration of the prescribed fluorescent composition of matter in the fluid as a function of applied UV fluence. There is also described a system for determining the UV fluence received by a fluid being treated in UV fluid treatment system comprising at least one UV source. The system comprises: (a) a radiation-transparent vessel for receiving a test sample of the fluid after irradiation of the fluid at an unknown UV fluence; (b) a fluorometer for measuring the fluorescence of the test sample received in the radiation-transparent vessel to produce a test signal proportional to the concentration of a prescribed fluorescent composition of matter comprised in the test sample; and (c) a controller configured to determine the value of the unknown UV fluence by comparing the test signal to a calibration curve of a control signal proportional to concentration of the prescribed fluorescent composition of matter in the fluid as a function of applied UV fluence.
