Abstract

Wastewater stream from industrial plants, including petroleum refineries, chemical plants, pulp and paper plants, mining operations, electroplating operations and food processing plants, may contain offensive substances such as cyanide, sulfides, sulfites, thiosulfate and disulfides that tend to increase the chemical oxygen demand (COD) of the wastewater streams. Thiosulfate is an oxyanion of sulfur produced by reaction of sulfite ions with elemental sulfur in high temperature water. As some countries have a limitation for thiosulfate concentration, especially in the wastewater stream, the removal of thiosulfate is one of the major concerns by most of industries. This research and experimental project will be focusing in removal thiosulfate by using Air Advanced Oxidation Process (AOP). In this particular project, air is use as the medium because it is an unlimited source and oxidation process is naturally happen in the atmosphere. The experiment will be conduct in chemical laboratory. Some parameters such as thiosulfate and oxygen concentration, air fiowrate, pH and temperature will be manipulate, monitor, record and finally the data will be trend for analyze process. These factors are believed to be the important factors in the real environment of removing thiosulfate. The expected result of the experiment is the thiosulfate concentration drop and sulfate formation. The analysis of the result will be done using UV Visible Spectrophotometer to determine the effectiveness of the study. At the end of the project, the kinetic model for the process would be developed.
