One of the industrial areas in the south of Iran is Bandar Imam Petrochemical Economic Zone which has a lot of petrochemical complex, Farabi Petrochemical complex is one of those places. Coagulation/flocculation could be a typical methodology in water and wastewater treatment that a number of chemicals are added to assist the coagulation/flocculation and causes to the sedimentation. In this pap...

Hydrocarbons are widespread in the environment, but because of the massive utilization of petroleum products, they are nowadays strongly involved in environmental pollution. Bioremediation is the obliging technology for the treatment of hydrocarbon-contaminated sites. Therefore, to investigate the potential of petrochemical hydrocarbon (HC)-degrading indigenous microorganisms in wastewater samp...

background heat, chemical and organic pollution are three types of environmental pollution, caused by refinery and petrochemical industries. problems caused by hear and chemical pollutants are currently resolved to some extent but organic pollution such as poly aromatic hydrocarbons (pahs) are still considered as important problems of industry and environment. objectives a laboratory study was ...

evaluation and modeling of the wastewater treatment plants (wwtp) have to be based on thefact that the pollutant concentrations and flow rates change constantly. in addition, different approaches mustused due to there are different processes in a wwtp. a mexican petrochemical complex has a wwtp thatprocesses wastewaters from several petrochemical plants, where the flow rates and pollutant conce...

The industrial wastewater treatment is gaining more and more importance with the rapidly increasing need for expansion of existing plants and erection of new plants to cater the needs of chemical, pharmaceutical and petrochemical products and intermediates. The treatment of the wastewater is key to the sustainable and acceptable industrial growth. Petroleum industries and refineries are importa...

The paper provides a critical comparison between mesophilic and thermophilic anaerobic treatment of PTA wastewater through diagnosis of a case study. Aspects covered are bioavailability, biodegradability, microbial population, thermodynamics, kinetics involved and bioreactor design for PTA wastewater treatment. The results of the case study suggests that onestage thermophilic anaerobic reactor ...

Radiation processing was found effective in wastewater purification and disinfection, and has been investigated in many countries through laboratory scale and pilot scale facilities. This technology can be applied to the treatment of industrial wastewater from textile dyeing industries, papermill and petrochemical processes, and also for the reclamation of effluent from municipal wastewater tre...

In this study, the feasibility of cruxrhodopsin (CR) production as a multifunctional nanoparticle was investigated and optimized by Halorculasp. IRU1, a novel halophile Archaea isolated from Urmia Lake, Iran in batch experiments. In this case, Taguchi method was used for effect measurement of three important factors (petrochemical wastewater, yeast extract and KH2PO4) on CR production. Results ...

Petrochemical industry generates highly toxic effluents with a large variety of chemicals, being most of them recalcitrant and toxic such as: organic chlorinated compounds (mainly 1,2 dichloroethane) and volatile and semivolatile organic compounds. The most common wastewater treatment systems used in Mexico to treat this kind of effluents are activated sludge and aerated lagoons. Treatibility s...
