  • Seawater Desalination

    Seawater covers 71% of the planet surface and represents 97% of the world's water,and seawater has a lot of resources to be explored.Along with recycled wastewater, it is one of the few rainfall-independent water sources.However,in the current condition,seawater cannot be used directly because of the high salinity.To solve it,many methods of desalination are adopted. Desalination is a process ...

  • Potentiating toxicological interaction of single‐walled carbon nanotubes with dissolved metals

    The present study explores the ecotoxicology of single‐walled carbon nanotubes (SWCNTs) and their likely interaction with dissolved metals, with a focus on the effect of in vivo exposure in marine mussels. Any nano‐scale effects were negated by the tendency of uncoated SWCNTs to agglomerate in water, particularly with high ionic strength as is the case in estuarine and full strength seawater. ...

  • Solar inactivation of four Salmonella serovars in fresh and marine waters

    Sunlight-mediated disinfection of water is of interest to both the drinking and recreational water quality community of researchers due to its potential to reduce microbial contamination and waterborne illness. Photo-inactivation of enteric bacteria has primarily been investigated using Escherichia coli and laboratory strains of model bacteria. The present study sought to document the ...

  • Comparison of enterovirus and adenovirus concentration and enumeration methods in seawater from Southern California, USA and Baja Malibu, Mexico

    Despite being important etiological agents of waterborne illness, the sources, transport and decay of human viruses in recreational waters are not well understood. This study examines enterovirus and adenovirus concentrations in coastal water samples collected from four beaches impacted by microbial pollution: (1) Malibu Lagoon, Malibu; (2) Tijuana River, Imperial Beach; (3) Baja Malibu, Baja ...

  • Boron removal by activated carbon and microfiltration for pre-treatment of seawater desalination

    This study aimed to enhance boron removal through powdered activated carbon adsorption (PAC) and application of a micro-filtration (MF) process as a pretreatment of a seawater reverse osmosis (SWRO) process. Batch and continuous experiments were conducted to investigate the effect of membrane filtration as well as PAC addition on boron removal in reconstituted seawater. In batch test, two kinds ...

  • Overview of seawater desalination status and challenges

    Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...

  • Submerged membrane coagulation hybrid system as pretreatment to organic matter removal from seawater

    In this study, a commonly used ferric chloride was utilised as coagulant for removing organic compounds from seawater. More than 57% of dissolved organic carbon (DOC) was removed at optimum dosage of 3 mg Fe+3/L. The coagulation by FeCl3 at optimum dosage could remove a majority (95%) of hydrophobic compounds. The results from Liquid Chromatography – Organic Carbon Detector showed that only ...

  • Seawater reverse osmosis system for supplying potable water for airport in saudi arabia

    The Background Saudi Arabia General Authority of Civil Aviation (GACA) is responsible for constructing, managing, operating, and maintaining airports and air navigation infrastructure in Saudi Arabia. The city lacked adequate water production and distribution systems around the airport. GACA’s objective was to increase water production to meet projected growth in demand, and ...

  • Seawater reverse osmosis plant for india’s first 4,000 MW ultra mega power project

    The Facility India’s first Ultra Mega Power Project (UMPP) at Mundra in Coastal Gujarat, a 4,000 MW coal fired plant, is owned by Coastal Gujarat Power Limited (CGPL), a Tata Power group company. Tata Power is India's largest private sector power utility with an installed generation capacity of over 2,300 MW. The CGPL UMPP, awarded on a 20 year BOOT basis, will be India’s ...

  • Devolping Pre-treatment Strategy for SWRO Systems

    Typically open-sea water intake structures are constructed in the shallow areas where sea water depth is in the range of 3m up to 10m. Due to this SWRO plant with open intake will have source water with high debris, suspended solids and aquatic organisms requiring a very elaborate pretreatment system. Thus Pretreatment design becomes an important part for a long term operation of the seawater ...

  • Membrane cleaning skids prolong operating life of costly membrane filtration units
