Adsorption of Oil and Grease in Wastewater using Activated Carbon Derived from Sewage Sludge
نویسندگان
چکیده
Abstract Oil and grease are organic contaminants that detrimental to the environment. The high concentration of oil can cause clogging in sewer. Clogged sewers deteriorate sanitary conditions. Adsorption is one technique reduce wastewater. using natural resources overcome cost commercial activated carbon. Sewage sludge has potential as raw material for carbon because content. studies aim investigate capability derived from sewage remove restaurant were carried out batch experiment. Adsorbent dosage ranged 2-6 g/L, a contact time range 5-45 minutes was performed chemically KOH 4M physically at temperature 700°C 60 minutes. result shows optimum adsorbent 4 g/L 25 minutes, respectively. highest adsorption capacity 63.75 mg/g. Under observed data, fit second-pseudo-order, Langmuir isotherm indicated process chemisorption.

Nanocomposite TiO2/ASS (TiO2 nanoparticle coated sewage sludge-based activated carbon) was synthesized by the sol-gel method. The changes in surface properties of the TiO2/ASS nanocomposite were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and X-ray fluorescence. The prepared TiO2/ASS nanocomposite was applied for simultaneous removal of methyl orange dye (MO) an...
متن کاملRemoval of Phenolic Compounds from Water Using Sewage Sludge-Based Activated Carbon Adsorption: A Review
Due to their industrial relevance, phenolic compounds (PC) are amongst the most common organic pollutants found in many industrial wastewater effluents. The potential detrimental health and environmental impacts of PC necessitate their removal from wastewater to meet regulatory discharge standards to ensure meeting sustainable development goals. In recent decades, one of the promising, cost-eff...
متن کاملModeling and Experimental Prediction of Wastewater Treatment Efficiency in Oil Refineries Using Activated Sludge Process
In this study, activated sludge process for wastewater treatment in a refinery was investigated. For such purpose, a laboratory scale rig was built. The effect of several parameters such as temperature, residence time, effect of Leca (filling-in percentage of the reactor by Leca) and UV radiation on COD removal efficiency were experimentally examined. Maximum COD removal efficiency was obtained...
