  • Removal of calcium and magnesium ions from shale gas flowback water by chemically activated zeolite

    Shale gas has become a new sweet spot of global oil and gas exploration, and the large amount of flowback water produced during shale gas extraction is attracting increased attention. Internal recycling of flowback water for future hydraulic fracturing is currently the most effective, and it is necessary to decrease the content of divalent cations for eliminating scaling and maintaining ...

  • Strategies to optimize phosphate removal from industrial anaerobic effluents by magnesium ammonium phosphate (MAP) production

    Owing to more stringent phosphate discharge requirements and the increasing prices of fertilizers, beneficial recovery and reuse of phosphate from industrial anaerobic effluents is becoming an important issue. Phosphate recovery by struvite or magnesium ammonium phosphate (MAP) permits its recycling in the fertilizer industry because struvite is a valuable slow release fertilizer. Two different ...


  • Magnesium ions improving the growth and organics reduction of Rhodospirillum rubrum cultivated in sewage through regulating energy metabolism pathways

    Rhodospirillum rubrum has the potential for biomass resource recycling combined with sewage purification. However, low biomass production and yield restricts the potential for sewage purification. This research investigated the improvement of biomass production, yield and organics reduction by Mg2+ in R. rubrum wastewater treatment. Results showed that with ...

  • Wastewater Treatment & Recycle

    Fresh water is a scarce commodity; this fact is well acknowledged by one and all. People at all levels be it general public, governmental bodies, and industries understand the implications of good quality water availability in terms of quantity, cost and wastage. As a consequence, there is a growing consensus on wastewater treatment for recycle/reuse. This paper briefly describes the treatment ...

  • New ways for Metal Recycling

    REWAVE XRF 3-way-sorting in innovative  “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it ...

  • Recycling of coal seam gas-associated water using vacuum membrane distillation

    Coal seam gas-associated water (CSGAW), which is a by-product of coal seam gas (CSG) production typically contains significant amounts of salts and has potential environmental issues. In this study, we optimized a bench-scale vacuum membrane distillation (VMD) process with flat-sheet hydrophobic polytetrafluoroethylene (PTFE) membranes for the treatment of synthetic CSGAW (conductivity = 15 ...

  • Ammonium removal from wastewater via struvite pyrolysate recycling with Mg(OH)2 addition

    Magnesium ammonium phosphate (MAP) pyrolysate recycling technology was investigated with Mg(OH)2-mediated pyrolysis. The results revealed that the removal ratio of ammonium was stable at about 75%, and could be increased to 79% after additional acidolysis. The phosphate concentration in the supernate was low at 2 mg/L. The optimum conditions for ammonia release were a 1:1 molar ...

  • Removal of ammonium from aqueous solutions using the residue obtained from struvite pyrogenation

    This paper reports the results of laboratory studies on the removal of ammonium from aqueous solutions using struvite pyrogenation residues. A series of experiments were conducted to examine the effects of the pyrogenation temperature (90–210 °C) and time (0.5–4 h) on the ammonium release of struvite. In addition, the pyrolysate of struvite produced at different pyrogenation temperatures and ...

  • Ammonium removal from aqueous solutions by zeolite adsorption together with chemical precipitation

    The aim of this study was to remove ammonium from aqueous solution and recycle ammonium. Ammonium removal from aqueous solution by natural and pretreated zeolites, breakthrough curve, chemical regeneration of pretreated zeolite, ammonium removal from regeneration solution by chemical precipitation and NH4+ adsorption isotherms were investigated by conducting a series of batch and continuous ...

  • Green machine takes new tangent on wastewater reuse

    The idea came to Jason Snydmiller while he was on the island of Borneo. At the time, Snydmiller had learned that the super-major – one of the six largest non-state-owned energy companies – he was under contract to would promptly fine any contractor that left oil in local waters. Although it seemed callous then, the rule was essential, since locals depended on the water for fishing and prawn ...

    As part of the ambitious £100 million restoration project, new water softening equipment from Kinetico has been installed at the recently re-opened Savoy in London, one of the world’s great, iconic hotels. The Kinetico system will eliminate problems with hard water, helping to maintain the efficiency and performance of building services plant whilst making sure that surfaces and ...

  • California’s city of roseville chooses HERO ZLD

    The Facility The Roseville Energy Park (REP) will be a natural gas-fired, combined-cycle electrical generating facility. The project, planned for a 12-acre site, will be owned by the city and will use state-of-the-art equipment to locally generate about 60 percent of Roseville’s electricity needs. The Roseville Energy Park will use recycled wastewater from the nearby Pleasant Grove ...

  • Husky tucker lake project -- an aquatech sagd installation

    The Facility Husky Energy is a Canadian-based energy and energyrelated company headquartered in Calgary, Alberta. Husky’s operations can be divided into three distinct business segments: Upstream, Midstream and Refined Products. The Oil Sands (Upstream Segment) of northern Alberta are one of Husky’s long-term growth areas. Husky has more than 425,000 acres in the Athabasca, ...

  • Identification of a Chlorophyll Dephytylase Involved in Chlorophyll Turnover in Arabidopsis

    Abstract Chlorophyll turns over in green organs during photosystem repair and is salvaged via de- and re-phytylation, but the enzyme involved in de-phytylation is unknown. We have identified an Arabidopsis thaliana thylakoid protein with a putative hydrolase domain that can dephytylate chlorophyll in vitro and in vivo. The corresponding locus, CHLOROPHYLL DEPHYTYLASE1 (CLD1), was ...
