  • Salinity Impacts to Water Recycling in Southern California

    ABSTRACTIn 2000, U.S. Bureau of Reclamation (Reclamation) and twelve cost sharing partners began the Southern California Water Recycling Projects Initiative (Initiative), which is a multiyear planning study. This study was established to assist local agencies in their recycled water planning for specific projects as well as addressing regional issues that may influence water recycling in southern ...

  • Salinity modeling for the Altona sewerage strategy

    City West Water’s Altona sewerage system is possibly one of the most studied sewerage networks in Melbourne, Australia. Currently the tertiary sewage effluent from the Altona treatment plant is discharged to Port Philip Bay with an average salinity of approximately 4500 mg/litre.  This study involved the development of a detailed model that accurately reflected the sources and dilution of ...

  • Optimization of direct-osmosis–high-salinity cleaning for reverse osmosis fouling control in water reuse

    This paper focuses on the systematic approach adopted towards optimizing the salt consumption when using direct-osmosis–high-salinity (DO-HS) cleaning method for RO membranes in water reuse application. Trials were carried out on a pilot RO system with a capacity of 50 m3/day. Initially, proof of concept for the DO-HS method in water reuse application was established wherein the profile of ...

  • Cost effective way to harvest estuarine water: variable salinity desalination concept

    Singapore, a small island city-state with some 700 km2 in land area and a population of 4.5 million, is always looking for innovative ways to find new water sources to meet its growing need for water. Rain falling in the urban fringe catchments is not harvested; these areas experience bouts of heavy rain but dry up during the dry season and, as such, the conventional approach of constructing ...

  • Potassium induced salinity tolerance in wheat (Triticum aestivum L.)

    Water culture experiments were conducted to study the response of ten wheat genotypes to external K application (10 mmol KCI dm_3) at seedling stage under saline condition (0 and 100 mmol NaCl dm_3). The data showed that there was an increase in the shoot and root length with the application of external K. The increase was more pronounced under control than under saline conditions. The better ...

  • Isolation of high-salinity-tolerant bacterial strains, Enterobacter sp., Serratia sp., Yersinia sp., for nitrification and aerobic denitrification under cyanogenic conditions

    Cyanides (CN−) and soluble salts could potentially inhibit biological processes in wastewater treatment plants (WWTPs), such as nitrification and denitrification. Cyanide in wastewater can alter metabolic functions of microbial populations in WWTPs, thus significantly inhibiting nitrifier and denitrifier metabolic processes, rendering the water treatment processes ineffective. In this study, ...

  • High Efficiency Softening Process (HESP) for Frack Flowback - produced water treatment study for City of Grand Prairie, TX

    Barnett Shale play in Texas, the natural gas economy According to Potter, the 5,500 wells currently pumping gas in the Barnett Shale play will ultimately generate on the order of $35 billion for their owners. As those companies pay taxes and wages, and as their employees and contractors in turn spend their money, there is an economic ripple effect, creating an overall value of ...

  • UV Ballast Water Treatment Close to US Approval

    Shipowners have found it increasingly difficult to comply with ballast water treatment regulations in the US. But there’s good news on the horizon thanks to DESMI’s newest UV-based solution Ultraviolet radiation (UV), which counters microorganisms by rendering them unable to reproduce, is the preferred method for today’s ballast water treatment systems. This robust and reliable ...

  • Kenya water treatment plant powered by coal seam methane, Australia - Case Study

    Kenya Water Treatment PlantQGC has contracted GE Water and Laing O’Rourke to develop a water treatment plant to convert saline associated water to fresh water for use by local residents. Clarke Energy was contracted to supply, install, and commission power modules to provide a reliable source of power for this plant using coal seam methane from QGC’s Kenya gas field. The power ...

  • Treatment of leachate using the DMT MemBioRex® technology

    One of the most difficult waste waters to treat is leachate from a landfill. Leachate is water from the degrading waste and rainfall which percolates through the waste. Leachate usually contains a high concentration of ammonium, low concentrations of phosphor, high salinity, high alkalinity and various concentrations of heavy metals. Combined with strongly fluctuating flows, a high pH and ever ...

  • Thermodynamic modelling of a membrane distillation crystallisation process for the treatment of mining wastewater

    Membrane distillation (MD) could be applicable in zero liquid discharge applications. This is due to the fact that MD is applicable at high salinity ranges which are generally outside the scope of reverse osmosis (RO) applications, although this requires proper management of precipitating salts to avoid membrane fouling. One way of managing these salts is with MD crystallisation (MDC). This ...

  • Compost' leachate recycling through land treatment and application of natural Zeolite

    Abstract Background: The entrance of untreated wastewater or disposal leachate to water resources such as surface water, groundwater or irrigation water increases the risk of contaminant accumulation. Removal or deduction of water contaminant concentration is then crucial before entering water to the natural resources or its transfusion directly to the soil as irrigation water. Four studies ...

  • High performance boron removal from seawater by two-pass SWRO system with different membranes

    Boron in the desalinated water produced by the seawater reverse osmosis (SWRO) system is one of the most challenging issues for drinking or irrigation water uses. In recent years, many post-treatment methods and designs for boron elimination have emerged and attracted lots of attention, but only a few cases have demonstrated high performance and economic efficiency. The main aim of this work was ...

  • Recycled Water saves California Farms

    After studies show no viable microorganisms in tertiary treated wastewater, growers in Salinas Valley now get two-thirds of their agricultural water needs from recycled sources. RECYCLED water is saving the farm for approximately 75 growers in the Salinas Valley along California’s Central Coast. Because their wells were becoming contaminated with seawater, these growers began irrigating their ...
