  • Seawater Aquarium Case Study

    Challenge The AquaDom aquarium is the biggest freestanding cylindrical aquarium in the world. It is home to 1500 fish and corals of 97 different species. All its 1000 m³ of water are recycled every hour in order to maintain the appropriate water conditions for sustaining life. Due to the recirculation of the water and the ineffectiveness of their phosphate removal filter, the level ...

  • Sohar Refinery

    Project Background Orpic (Oman Oil Refineries and Petroleum Industries Company) required a thermal seawater desalination solution as part of its Sohar refinery improvement project to ensure an uninterrupted supply of fresh feed water to for its boilers. ...

  • Filtronics offers toilet to tap solutions for its clients nationwide

    Filtronics first opened its doors in 1974, and in the nearly for decades since it has been their mission to provide efficiency and economy in the water treatment systems they create. Surface water, ground water and  ...

  • 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 ...

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

    Considered one of the most important and costly components of a reverse osmosis purification system, membrane filtration elements (a thin semi-permeable layer which desalinates seawater) collect mineral buildup, organic materials and bacterial agents. The Lifestream Membrane Cleaning Skid cleans, flushes out and preserves the membrane, reviving efficiency and prolonging membrane life.Designing a ...

  • Can we reposition the preferred geological conditions necessary for an infil

    The quantity and quality of feed water for desalting is critical for efficient operation of a desalination plant. This paper considers a synthetic permeable system designed to take advantages of the advances in directional drilling as well as incorporate the use of geotextile fabrics to transfer the preferred infiltration characteristics to any coastal site. The filtered seawater collection ...


  • Low cost processes for the removal of phosphates in water and wastewater

    This paper presents a synopsis of various low-cost techniques employed for the removal of phosphates from water and treated wastewater. Techniques employed include seawater flocculation and coagulation/flocculation using bittern, adsorption on fluidised raw dolomite bed, and filtration through iron and aluminium coated filter media. Seawater flocculation at a seawater concentration of 10% ...

  • Micro-media filtration: superior pre-filtration for desalination systems

    Introduction To ensure trouble free-operation of seawater desalination systems, membrane manufacturers recommend removal of suspended solids to negligible levels, as even small amounts of solids adhering to the surface of the membrane elements may adversely foul the membranes, deteriorate permeate quality and reduce membrane life. The past two decades have seen a dramatic increase in the ...

  • Membranes, the Finest Filtration

    Introduction The notion that salt could be removed from seawater without a phase change took hold of Dr. Sourirajan's imagination in the late 1950's. The actual invention of the reverse osmosis (RO) membrane took place in his laboratory at UCLA around 1960. (Thus Sourirajan could be called not only the 'Father of Reverse Osmosis,' but the initiator of all crossflow membrane technology.) The full ...
