Adsorption Purification of Phenol-Containing Wastewater from Oil Refineries

Comparative Studies on Simultaneous Adsorption and Biodegradation, Adsorption and Biodegradation for Treatment of Wastewater containing Cyanide and Phenol

This paper presents a comparative study of the efficiency of biodegradation, adsorption and simultaneous adsorption and biodegradation (SAB) process for the remediation of industrial wastewaters containing both cyanide and phenol. Adsorption was carried out using granular activated carbon (GAC), while biodegradation was achieved by co-fermentation with Pseudomonas putida and Azotobacter chrooco...

Hydrogen Detection in Oil Refineries

Modeling 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...

Development of Phenol-Enriched Olive Oil with Phenolic Compounds Extracted from Wastewater Produced by Physical Refining

While in the last few years the use of olive cake and mill wastewater as natural sources of phenolic compounds has been widely considered and several studies have focused on the development of new extraction methods and on the production of functional foods enriched with natural antioxidants, no data has been available on the production of a phenol-enriched refined olive oil with its own phenol...

Environmental Regulation and Productivity: Evidence from Oil Refineries

We examine the effect of air quality regulation on productivit y in some of the most heavily regulated manufacturing plants in the United States, the oil reŽ neries of the Los Angeles (South Coast) Air Basin. We use direct measures of local air pollution regulation to estimate their effects on abatement investment. ReŽ neries not subject to these regulations are used as a comparison group. We s...
