Abstract

Phenol and chloroform are general contamination present in many types of industrial wastewaters, and there is a special concern due to their characteristics such as high toxicity, carcinogenic behavior, and pivotal, pool ability that impact the health of humans and the environment. The modified Perspex loop reactor (MPLR) was tested in the current study with 26 liters as effective volume, having an internal tube with 5 cm diameter extending 120 cm vertically inside the center of the reactor that contains [7.5 * 30 cm] an expanded bed at the end of its top-end which fills with (granular activated carbon (GAG) or rice husks) as adsorbent materials. In this study, Four operational variables were tested, the concentration of the pollutant in the feeding stream, the molar ratio of the organic pollutant to oxidant agent, the residence time, and the type of adsorbent material. The results analysis indicates that the efficiency of removal for phenol is (89%),(85%) and for chloroform is,(83%),( 81%) when using GAC and the rice husk as adsorbent materials respectively, accompanied with a suitable treating period 60 minutes, optimum airflow rate is 18 L/min,  and a molar ratio(20) for hydrogen peroxide to phenol.
