Coagulation Water Treatment vs. Electrocoagulation Treatment
There are many ways to treat water, and one of the most common tactics is coagulation. This method provides clean, safe water and is typically used alongside other standard processes like sedimentation, disinfection, and filtration. All of these methods assist in removing contaminants from water. However, while coagulation water treatment is a good conventional option, a better solution exists ...

How has UF Water Treatment Systems Assisted Oil/Gas Companies
In the oil and gas industry, water and wastewater treatment comes into play in mining operations and refineries. UF water treatment systems are used in tertiary process applications in these industries to assist oil/gas operators and oil/gas refineries to obtain suitable water for produced water reuse for fracking operations or sustainable discharge. Mining for oil happens both on and off-shore. ...

Electrocoagulation Provides an Economical Produced Water Solution to Oil & Gas Companies
Oil and natural gas are considered valuable resources all across the globe. The number of products made from these two materials is impressive and our lives would be very different without them. Production of these products begins with locating the underground sources of crude oil. These deep well sources are then mined to extract the oil and gas materials. Afterward, these raw materials are sent ...

Benefits of Electrocoagulation for Remediation of Refinery Wastewater
Refinery Wastewater: Benefits of Remediation by Electrocoagulation Crude oil is a fossil fuel formed from long-dead organisms subjected to intense heat and pressure underground. This resource is the main ingredient in the production of gasoline, diesel fuel, lubricants, kerosene, propane, and asphalt. All of these products can be made in a single refinery through a complex branching series of ...

Water Use and Reuse in Petroleum Refining
Refineries can be like cities, and opportunities for water reuse abound, from recycling of process water to sewage Although the water requirements of oil exploration make water reuse a hot topic for the upstream petroleum industry — the exploration and production end — there are significant opportunities for reuse downstream, which includes refining. Petroleum refineries are ...

Efficient high strength petrochemical wastewater treatment in a hybrid vertical anaerobic biofilm (HyVAB) reactor: a pilot study
Performance of a pilot scale Hybrid Vertical Anaerobic Biofilm (HyVAB) reactor treating petrochemical refinery wastewater is presented here. The reactor is an integration of a bottom anaerobic sludge bed and a top aerobic biofilm stage and was operated continuously for 92 days at 21 ± 2 °C. Wastewater was fed continuously to the reactor with step flow increases reducing hydraulic retention ...

Evaluating photo-degradation of COD and TOC in petroleum refinery wastewater by using TiO2/ZnO photo-catalyst
The aim of this study is to investigate the performance of combined solar photo-catalyst of titanium oxide/zinc oxide (TiO2/ZnO) with aeration processes to treat petroleum wastewater. Central composite design with response surface methodology was used to evaluate the relationships between operating variables for TiO2 dosage, ZnO dosage, air flow, pH, and reaction time to identify the optimum ...

MBBR system performance improvement for petroleum hydrocarbon removal using modified media with activated carbon
Moving bed biofilm reactor (MBBR) system has a successful operation in the treatment of different types of wastewater. Since the media, i.e. the place of growth and formation of biofilm, play the main role in the treatment in this system, MBBR systems were operated in the present research with modified Bee-cell media. Activated carbon granules of almond or walnut shells were placed in media ...

Adsorption of polycyclic aromatic hydrocarbons from wastewater by using silica-based organic–inorganic nanohybrid material
Polycyclic aromatic hydrocarbons (PAHs) are a group of priority pollutants, which are classified as persistent hazardous contaminants. Herein, the adsorption of three PAHs, naphthalene (NAP), acenaphthylene (ACN), and phenanthrene (PHN), from wastewater onto NH2-SBA-15 organic–inorganic nanohybrid material as a function of pH of the media (2–10), sorbent dosage (0.5–3.5 g ...

Removal of sulfur compounds from petroleum refinery wastewater through adsorption on modified activated carbon
The adsorption of sulfur compounds from petroleum refinery wastewater on a chemically modified activated carbon (MAC) was investigated. The modification technique (nitric acid, hydrogen peroxide and thermal modification) enhanced the removal capacity of carbon and therefore decreases cost-effective removal of sulfide from refinery wastewater. Adsorption equilibrium and kinetics data were ...

An integrated approach for source contribution estimation: a case study
The efficiency of the CMB model for source contribution estimate is determined by the availability of accurate source profiles and therefore its use is limited when source profiles are not known. In this study the source contribution estimate of ambient VOC was carried out using the CMB model with the source profiles obtained from the PMF model. The PMF model fitted the monitored dataset very ...
