  • Common challenges relative to the use of Decanter Centrifuges for barite recovery in the oil & gas industry

    When centrifuges are properly deployed, they can have dramatic effects on drilling performance. In fact, without them, many of the advances made in drilling would not have been considered achievable. Classically, we believe that centrifuges can achieve two common goals: Reduce the content of drilled fines, specifically colloidal solids, and Perform barite recovery in order to reduce ...

  • Bio-remediation of pendimethalin contaminated soil by bio-slurry phase reactor: bio-augmenting with ETP micro-flora

    Bio-remediation of pendimethalin contaminated soil (500 µg/g) was studied in a bio-slurry phase reactor operated in the sequencing batch mode under anoxic–aerobic–anoxic micro-environment. The effect of augmentation with ETP micro-flora on the process performance of the reactor was also evaluated. The reactor was operated with a total cycle period of 120 hours comprising 3 hours of fill, 114 ...

  • Salmon Processor

    The water is from a salmon processor where they are using an Andritz 3 phase decanter centrifuge to recover the oil in the salmon parts after packaging the salmon for human consumption. The oil is very valuable for use in the health food industry. The Andritz centrifuge recovers 90% of the oil from the wastestream, but leaves a residual oil emulsion that needs to be treated prior to discharge to ...

    Perry Township in Fayette County, Pennsylvania is one of the first SBR plants to utilize a surface mounted process aerator/mixer, which is a significant improvement over the traditional diffused air network designs. The new layout offers substantial capital investment savings as well as significant reductions in noise, operations/ maintenance, and energy consumption. KLH Engineers, Inc., ...

  • Equipment List for full solids manage & drilling waste

    Solids Handle & drilling waste management are pretty important for drilling contractor. If they manage this division well, they can save lots of money on drilling mud / drilling chemicals, also they can be environmental friendly. There is much equipment needed for solids control & drilling waste ...


  • Pollution reduction and biodegradability index improvement of tannery effluents

    Al2 (SO4)3, 18H2O, FeCl3 and Ca (OH)2 were used for the treatment of tannery wastewaters. The influences of pH and coagulant dosages were studied. Conditions were optimised according to the pollutant removal efficiencies, the volume of decanted sludge and the biodegradability index improvement. The results indicate that 67-71% of total COD, 76-92% of color and 79-97% of chromium can be removed ...

  • ORP and pH Based Control of SBR Cycles for Nutrient Removal from Wastewater

    ABSTRACTContinuous monitoring of multiple process functions were conducted involving removals of BOD, TSS and nutrients, in each cycle of the SBR reactor at the wastewater treatment plant of the City of Carrabelle, FL. On line, real time, monitoring of pH, oxidation reduction potential (ORP), dissolved oxygen (DO), ammonia-N, nitrite-N, nitrate-N and orthophosphate-P demonstrated excellent ...

  • Development and optimization of a sequencing batch reactor for nitrogen and phosphorus removal from abattoir wastewater to meet irrigation standards

    A sequencing batch reactor (SBR) was used for the treatment of abattoir wastewater to produce effluent with desirable nitrogen and phosphorus levels for irrigation. The SBR cycle consisted of an anaerobic phase with wastewater feeding, a relatively short aerobic period (allowing full ammonium oxidation), a second anoxic period with feeding, followed by settling and decanting. This design of ...

  • The use of oilfield shale shaker

    Shale shaker for solids control are devices that remove drill cuttings from the drilling fluid while circulating and drilling. There are many different designs and research into the best design is constantly ongoing since drilling fluids solids control is vital in keeping down costs associated with the drilling ...


  • Usen

    “Oil is not only an important sector of our industry but also a symbol of the independence of our country, of the hope for a better future”. These were the words of President Nursultan Nasarbayev in September 1999, commemorating the 100th anniversary of the formation of the oil and gas industry. The oil industry in Kazakhstan has existed for more than 100 years, however a significant boom in this ...

  • A perfect pair: SBR designs & advanced aeration technology

    Conventional sequencing batch reactors (SBRs) that utilize diffused-air networks have existed in the U.S. for about three decades now. The reliability of controls and instrumentation has significantly improved in the last 10 to 15 years, and as a result, SBR plant designs are becoming more widely accepted. The attractiveness of their compact layout and ease of operation has also helped increase ...

  • Limitations of the removal of cyanide from coking wastewater by ozonation and by the hydrogen peroxide-ozone process

    The purpose of this study is to compare the efficiency of ozonation and the hydrogen peroxide–ozone process for the removal of cyanide from coking wastewater. The most efficient oxidation process is combined with coagulation–flocculation–decantation and lime–soda ash softening pretreatments. The oxidation in aqueous solution and industrial wastewater (at pH 9.5–12.3) by O3 was carried out ...

  • Dynamics of nitrogen oxides emission from a full-scale sludge liquor treatment plant with nitritation

    Biological treatment in wastewater treatment plants (WWTPs) is a source of nitrogen oxides (N2O, NO and NO2) emitted to the atmosphere. Aerobic ammonia-oxidising bacteria (AOB) have been suggested to be the main source of these emissions. In a full-scale sludge liquor treatment plant at Sjölunda WWTP, it was shown that significant emissions of N2O, NO and NO2 do occur. The plant is operated with ...
