  The reaction of disinfectants with natural organic materials (NOM) existing in water lead to the formation of Disinfection By-Products. Potentially hazardous and carcinogenic characteristics of THMs recognized. Thus removal of THMs or THMs precursor is necessary for human health the aim of this study was to research of efficiency of domestic reverse osmosis (RO) in removal of trihalomethanes (THMs) from drinking water. In this study was used pilot scale of RO system with Polyamide membrane as Spiral-Wound, Tape wrapping module. Feed solution was made by using of pure chloroform. The samples containing chloroform were analyzed using a gas chromatograph, which equipped with a flame ionization detector. By increasing the flow, the removal rate of chloroform decrease and with declining removal of EC, the removal of chloroform was declined too. In this research, at worst condition, the efficiency of the pilot scale reverse osmosis reached to 80 % removal of chloroform.

  An aerated submerged fixed-film (ASFF) bioreactor was developed to treat an artificial wastewater based on crude oil. Bee-Cell 2000 was used as support media having porosity of 87% and a specific surface area of 650 m2 m-3. The system was able to achieve 70.87-93.12% removal efficiencies of Chemical Oxygen Demand (COD) in the organic loading rate range of 1.310 to 15.797 g COD m-2 day-1. Data gained exhibited that the effluent COD concentration ranged between 68.68 and 292.60 mg L-1 at organic loadings experienced. Therefore, an ASFF process showed that it was feasible to treat high oily wastewater in order to meet the discharge standards.
