Abstract: The properties and amount of NOM (natural organic matter) can hardly affect the process efficiency and it is known that raw water total organic carbon (TOC) levels have a potential to produce concentrations of trihalo methanes (THM ). In order to improve and optimize these processes, the characterizat ion and quantification of NOM at different purification and treatment processes stages is important. In this wo rk, e xperimental measurements were conducted to reduce the concentration of general organic co mpounds in the natural organic matter (NOM) existing in s mall amounts of Uberabinha River water in Brazil. Treat ment was tested for its efficacy to reduce raw water NOM using gravity filt ration with recycled granular act ivated carbon (RGA C) adsorption. Samp les of filtered were collected in intervals of one hour and were analyzed for conductivity, pH and UV254 absorbance. It was verified that pH and conductivity of the final p roduct have not changed comparing to the raw water in itial values. Also, the influence of pressure and the carbon particle size was clearly observed in the quantity and quality of the filtered. In a nutshell, RGAC was capable of reducing organic compounds concentration to an acceptable level encouraging its recycling and use.
