Background: Phenolic compounds are found in wastewater of many industries such as pulp and paper, textile, petrochemical, oil refineries, production of phenolic resins, plastics, coal furnace, tannery, rubber reclamation plant, fertilizers, coke, paints, rubber, decolorizer, resins, rubber and phenol- formaldehyde resin industries. This study aimed to evaluate Moving Bed Biofil...

the aim of this research is performance evaluation of reverse osmosis method for treatment of ion exchange resins regeneration wastewater from a petrochemical complex in iran. currently this wastewater is discharged to evaporation lagoons after neutralization. thus, we need to set up a pilot plant which has membrane cell for treatment performance evaluation of three kinds of reverse osmosis mem...

This study describes the temporal and spatial variability of bacterial communities within a combined sewer system in England. Sampling was conducted over 9 months in a sewer system with intensive monitoring of hydraulic conditions. The bacterial communities were characterized by 16S rRNA gene-targeted terminal restriction fragment length polymorphism analysis. These data were related to the hyd...

Oily wastewater is generated from various sources within the petrochemical industry, including extraction, refining and processing, storage, transportation. Over years, large volumes of oily this industry have made their way into environment, negatively affecting human health, economy. The raw waters can differ significantly complex features, making them difficult to treat. Membrane bioreactors...

Process plants such as petrochemical units have been continuously trying to improve Health, Safety, Environment and Ergonomics (HSEE) programs. This study proposes an adaptive network-based fuzzy inference system (ANFIS) for assessment of HSEE programs in a petrochemical plant. The proposed neuro-fuzzy approach is applied to a set of operators in the petrochemical unit to show its applicability...

The petrochemical industry is a large and complex industry that contributes heavily in the economy of many Middle-East countries. It is an industry that needs strategies for different aspects of planning and production. This work presents the main strategies that must be considered for the petrochemical industry together with the corresponding tools. The strategies are presented in the field of...

In this study, modified granular activated carbon (GAC) and immobilized cells were used to improve the biological efficiency of high-ammonia-nitrogen wastewater treatment using microorganisms. The results showed that sodium-hydroxide-modified (NaOH-GAC) greatly increased numbers ammonia-oxidizing bacteria Alcaligenes sp. TD-94 Paracoccus TD-10. Using NaOH-GAC number by 63.27% over GAC. Compared...
