For a long period of time, design and manufacturing technology of high flow rated vertically suspended pumps (VSPs) which have an extensive applications in many industries such as water and wastewater, mining, petrochemical and oil and gas industries, used to be imported from European countries. For the first time in Iran's pump industry, with the support of Ministry of Petrochemical[ah1]  and ...

Effluents discharged from petrochemical facilities are complex and composed of various types highly toxic contaminants, which necessitates the development sustainable treatment technologies. Stability is among most important sustainability criteria wastewater processes. In present manuscript, standard-reaching rate (η) index was used to evaluate stability catalytic ozonation process for treatin...

phenol is an environmental pollutant present in industrial wastewaters such as refineries, coal processing and petrochemicals products. in this study three phenol degrading bacteria from arak petrochemical complex effluent were isolated which consume phenol. molecular analysis was used to identify bacteria and isolated bacteria were identified as rhodococcus pyridinivorans (ns1), advenella faec...

The Dutos e Terminais do Centro Sul (DTCS) is one of the largest petroleum terminals of the South America located in the São Sebastião Channel (SSC) on the southeastern Brazilian coast. The aims of this study were to compare the sediment quality near the DTCS with that of several sites in the SSC region including the Araçá (AR) domestic sewage outfall and to assess the efficiency of the DTCS wa...

Phenol is a common wastewater contaminant from various industrial processes, including petrochemical refineries and chemical compounds production. Due to its toxicity to microbial activity, it can affect the efficiency of biological wastewater treatment processes. In this study, the efficiency of an Anaerobic Sequencing Batch Reactor (ASBR) fed with increasing phenol concentrations (from 120 to...
