A pilot study for oil refinery wastewater treatment using
Biological treatment of industrial oil refinery wastewater is a well-established method for remediation of these wastes. We have designed a new bioreactor system to increase the efficiency of biological treatment systems by (1) allowing greater organic loads, (2) minimizing production of sludge waste by-products, and (3) increasing process stability and resistance to shock loading.
Oily wastewater is produced in oil refining processes. This waste is usually treated by a number of physical, chemical, and biological techniques in water treatment units of oil refinery before
Oil Refinery Wastewater Treatment by Using Membrane
In this work, a new hollow fiber membrane was fabricated for the treatment of industrial wastewater in Al-Daura refinery in Baghdad using the submerged membrane bioreactor (MBR) technique with a new membrane-type module. The hollow fiber characterization seems to be within the range of ultrafiltration membranes, and the fabricated hollow fibers have a skinless porous outer surface.

Oil refinery wastewater treatment using coupled
Oil refinery wastewater was treated using a coupled treatment process including electrocoagulation (EC) and a fixed film aerobic bioreactor. Different variables were tested to identify the best conditions using this procedure. After EC, the effluent was treated in an aerobic biofilter.
The microfiltration of wastewater from vegetable oil refinery using alumina ceramic membrane with pore size of 200 nm proved to be adequate as a secondary treatment preceding discharge of wastewater into the recipient or its re-use in the industrial process.
Industrial Wastewater Treatment by Using MBR (Membrane
This study demonstrated the importance, process, activation and applications of Membrane in bioreactor to treat the waste water. Membrane Bioreactor (MBR) process consists of a biological reactor integrated with membranes that combine clarification and filtration of an activated sludge process into a simplified, single step process. Operating as an MBR allows conventional activated sludge
Anaerobic membrane bioreactor technology (AnMBR) combines the advantages of anaerobic treatment with membrane separation using a membrane bioreactor (MBR). Physical separation membranes are used in conjunction with anaerobic digestion to remove the maximum amount of organics while delivering the highest volume of biogas.

Surcis is a company specialized in respirometry systems and wastewater biological treatment processes. The compact and fast BM multipurpose respirometers are unique in the market. Thanks to their three different working modes and the faculty to run under different conditions of temperature, pH,
Using optimum conditions, treatment of oil bilge wastewater by electrocoagulation 93% biochemical oxygen demand, 95.6% oil and grease, 99.8% total suspended solids, and 98.4% turbidity. From this analysis, it was determined that the costs was $0.46/m 3 of oil bilge treatment was for energy and electrode consumption, chemicals, and sludge
Treatment of High-Concentration Wastewater from an Oil
A sequencing batch reactor (SBR) and a ceramic membrane bioreactor (CMBR) were used in conjunction (SBR+CMBR) to treat high-concentration oil and gas field wastewater (HCOGW) from the China National Offshore Oil Corporation Zhanjiang Branch (Zhanjiang, Guangdong, China). The chemical oxygen demand (COD) and the oil concentrations in the wastewater were 20,000–76,000 and 600–2200 mg
degradation of vegetable oil refinery wastewater novel separation techniques, including microwave-assisted extraction and more The volume presents selected examples in wastewater treatment, highlighting some recent examples of processes such as photocatalytic degradation, emulsion liquid membrane, novel photocatalyst for degradation of various
- What type of polyacrylamide is used in oil industry?
- The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
- What is nonionic polyacrylamide?
- Nonionic polyacrylamides Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.
- What is an anionic polyacrylamide?
- Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
- Are polyacrylamide gels ionic or Nonhydrolyzed?
- Nonhydrolyzed, and hence nonionic, polyacrylamide gels are used for electrophoresis media in biotechnology laboratories [ 72, 73 ]. Particulate polyacrylamide gels are useful in horticulture [ 74 ].
