in this report, experimental investigation of waste water treatment by reverse osmosis to enable its reuse in cooling tower is presented. a polyamide spiral wound ro membrane followed by three filters as ro pretreatment (two activated carbon and one cartridge filter) and samples of tehran refinery treated waste water have been used. the effect of operating conditions such as pressure difference...

Application of Granular Activated Carbon (GAC) in adsorption process has been studied for the advanced treatment of municipal and industrial wastewater. Because of entering poisonous compounds such as furfural, phenol and sulfides into the oily wastewater of Tehran refinery, biological aeration basins of wastewater treatment unit may not have the desired performance of COD reductio...

Petroleum refinery wastes contain mixtures of toxic compounds including Polycyclic Aromatic Hydrocarbons (PAH) which may pose genotoxic threats to the biota. The objective present study was assess potential wastewaters petroleum at Sapugaskanda, Sri Lanka using erythrocytic micronuclei and nuclear abnormalities as biomarkers in fish Oreochromis niloticus exposed wastewater under controlled labo...

BACKGROUND Contamination of water by toxic chemicals has become commonly recognized as an environmental concern. Based on our clinical observation in Mashhad, northeastern Iran, many people might be at risk of exposure to high concentrations of toxic heavy metals in water. Because wastewater effluents as well as water wells have been commonly used for irrigation over the past decades, there has...

The operational stability and continuity are key production characteristics of actual refinery processing units, which plays important role to safe and efficient production. While few literatures have given a sufficient and comprehensive expression of such characteristics. In view of the problem, this paper discussed refinery operations optimization based on operational stability and continuity...

The aim of this paper is to investigate whether simulated Jordan refinery wastewater can be treated through electrocoagulation (EC) conform the most stringent Jordanian norms for reusing irrigation cut flowers and perform cost analysis a treatment plant whose core are EC reactors. method used estimating fixed (capital) costs taken from literature based on study estimate (factored estimate) that...
