  • Coagulation pretreatment of highly concentrated acrylonitrile wastewater from petrochemical plants

    Acrylonitrile (AN) wastewater is a heavily polluted and a likely hazardous liquid that is generated during the production of AN. Several chemical methods for the pretreatment of AN wastewater are available in laboratory scale. However, the harsh reaction conditions and high operational cost make these methods undesirable. Until now, four-effect evaporation is the only pretreatment method used ...

  • Reclaimed water for the Tarragona petrochemical park

    The Camp de Tarragona Water Reuse Project is an emblematic example of how regional water scarcity can be overcome by considering reclaimed secondary effluent, which would otherwise be disposed of in the Mediterranean Sea, as an essential component of integrated water resources management. An advanced water reclamation plant (AWRP) was completed in 2011 to reclaim municipal secondary effluent ...

  • Wastewater Treatment & Recycle

    Fresh water is a scarce commodity; this fact is well acknowledged by one and all. People at all levels be it general public, governmental bodies, and industries understand the implications of good quality water availability in terms of quantity, cost and wastage. As a consequence, there is a growing consensus on wastewater treatment for recycle/reuse. This paper briefly describes the treatment ...

  • Biological Wastewater Treatment

    Untitled Document The use of microorganisms to remove contaminants from wastewater is effective and widespread. To choose the right system from the many options offered, ...


  • COD removal from petrochemical wastewater by UV/hydrogen peroxide, UV/persulfate and UV/percarbonate: biodegradability improvement and cost evaluation

    The petrochemical industry has been highly considered by environmentalists since it can affect the environment through the production of high strength wastewater. This study investigates chemical oxygen demand (COD) removal from petrochemical wastewater by ultra violet (UV)/oxidant systems with varying dosages of oxidants, initial pH values and reaction time. Hydrogen peroxide (H2O2), ...

  • Deployment of biokinetic modeling tools to optimize real time biological wastewater process control in the oil refining industry

    Perhaps no industry has more operationally failing wastewater treatment plants than those deployed in the Oil & Petrochemical market segments. These plants have some of the toughest influent contaminant profiles to treat, and suffer from some of the largest ranges of variation in contaminant loadings. The toughest area of wastewater process control in Oil Refining of course lies in the Biological ...

  • Combination of microwave demulsification, ozone oxidation and biological aerated filter for advanced treatment of oilfield wastewater with low biodegradability

    In this study, a combination process was developed in laboratory-scale including microwave demulsification, ozonation, and biological aerated filter (BAF) in series for the purpose of removing pollutants in oilfield wastewater with high microtoxicity. The microwave demulsification treatment removed 63.4% of oil. The ozonation treatment removed 79.3% of petroleum sulfonate, resulting in a ...

  • Major Breakthrough in Wastewater Nitrogen Removal

    Working together in close collaboration, the Hollandse Eilanden en Waarden Water Authority (Zuiveringsschap Hollandse Eilanden en Waarden, ZHEW) and Paques are pleased to announce the world's first system for sustainable nitrogen removal from waste water. In May of next year, an Anammox® system will be opened in the Dokhaven waste water purification plant of ZHEW in Rotterdam. Through the ...


  • Easy To Integrate: Dezentralised Treatment Of Process Water

    Technical processing systems are some of the most complex industrial plants in existence. In the petrochemical industry, lor example, a great number of chemical products can be manufactured from crude oil and natural gas as a result of chemical-physical processes using such systems. They are designed by special companies, such as the Engineering Division of Linde AG, which having installed over ...

  • Companies and people leading the restructured environmental services industry in Canada

    The landscape of environmental service providers in Canada has changed dramatically in the past four or five years, especially with mergers and acquisitions announced in recent months between some fast-growing businesses. Only a decade ago the industry was dominated by a couple of publicly-traded continental companies that gobbled up numerous small and medium-size enterprises to offer customers a ...

  • Toxicity reduction using powder activated Carbon

    Petroleum reserves, international politics and economic considerations are driving the domestic petrochemical industry toward heavy and sour crude slates. A consequence of the change is increased concerns related to the wastewater effluent toxicity. In 2005, a powdered activated carbon-activated sludge (PAC-AS) treatment process was installed at a petrochemical facility to reduce whole effluent ...

  • Degradation of aromatic compounds using moving bed biofilm reactors

    The removal of toxic phenolic compounds from industrial wastewater is an important issue to be addressed. Phenolic compounds such as phenol, hydroquinone and pyrogallol are used in different industries which end into their wastewaters. They are considered as priority pollutants because of their high toxicity at low concentrations. Phenol is an important raw material in petrochemical, ...

  • Toxicity Assessment Using a Dilution Series

    Toxicity, or more appropriately, inhibition, is a measure of the interference of a compound or compounds with biodegradation. Since inhibition usually is expressed as the interference with bioconversion of an oxygen-consuming reaction – or gas producing reaction in the case of anoxic or anaerobic reactions – it is essential that a biodegradable substrate be present when assessing toxicity of ...

  • Influence of nitrogen limitation on performance of a microbial fuel cell

    We describe the operation of a microbial fuel cell (MFC) system operating on a synthetic wastewater (acetic acid), under conditions of increasing nitrogen limitation. Two MFCs were operated under feed conditions which spanned a range of TKN/COD values of 1.6–28 mg/g. Stable operation was observed in all cases, even when no ammoniacal nitrogen was added to the cell. Improved electrochemical ...
