Abstract
The objective of this paper was to investigate the organic fraction (colloidal, particulate, and dissolved) in sewage treatment in treatment wetland. Performance of TWs was simulated well with a simple first order model k – C* based on monitoring data. In this investigation background or residual concentration (C*) was assumed to be equal concentration of input influent organic matter in particulate (CODp). Calculated reaction rate constants (kCOD) for each organic matter fraction showed that fraction present in particulate (CODp) undergoes a multiple-step removal process than it was originally estimated. Mass removal rates computed for COD fractions directly show a relationship between removal efficiency of organic matter and background concentration (C*), resulting in higher efficiency of the second and third treatment step.
