  • Optical Particle Counter Verification of Particle Concentrations in Filtered Seawater for Injection into Oil Reserves

    Abstract High particle levels in process chemicals have been shown to directly affect product quality. The need for continued reductions in particle size and quantity in cleanroom environments is well established. The International Technology Roadmap for Semiconductors (ITRS), sponsored by the United States Semiconductor Industry Association (SIA), defines the need for persistent ...

  • Optical Particle Counter Verification of Particle Concentrations in Filtered Seawater for Injection into Oil Reserves

    Abstract Seawater injection is a secondary recovery technique used in oil reservoirs to replace extracted oil and maintain well pressure. Oil reservoirs are typically found within the small pores of sedimentary rock formations, so it is imperative that the injected seawater does not contain suspended particle matter that can clog these pores and hinder oil recovery. Since untreated ...

  • How a new source of water is helping reduce conflict in the Middle East

    Scientists and others look to desalination as a way to unite longtime enemies in a common cause. Ten miles south of Tel Aviv, I stand on a catwalk over two concrete reservoirs the size of football fields and watch water pour into them from a massive pipe emerging from the sand. The pipe is so large I could walk through it standing upright, were it not full of Mediterranean seawater pumped ...

  • Working on a Love/Hate Relationship with the Surface Chemistry of Membrane Filters

    Water, oils, and solvents sometimes need to be filtered. But when you see filters labeled as hydrophilic, hydrophobic, and now oleophobic; what does all this mean?  Sterlitech currently offers membrane disc and sheet filters in 10 different polymer types and 4 inorganic filters. 2 of the polymer types are subdivided into 4 subgroups based on surface ...

  • Desalination gets a graphene boost

    Original story at MIT News Jeffrey Grossman applies new materials research to making desalination cheaper and more efficient. With the intensifying drought in California, the state has accelerated the construction of desalination plants. Yet due to high construction and operating costs, as ...

  • 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 ...

  • 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 ...

  • Application of backwashing with demineralized water for UF fouling control in UF-RO desalination

    The effectiveness of demineralized water backwash on ultrafiltration (UF) fouling control of seawater is investigated in this study. Fouling experiments for two different backwashes (UF permeate and demineralized water) were conducted at three fluxes: 120, 180 and 240 L/(h m2) to compare their fouling control efficiency on UF membranes. Results show that backwashing with demineralized water ...

  • Removal of micropollutants and NOM in carbon nanotube-UF membrane system from seawater

    One of the main problems for seawater reverse osmosis desalination is membrane fouling associated with natural organic matter. Bisphenol-A (BPA) and 17α-ethinylestradiol (EE2) are well-known endocrine-disrupting compounds that have been detected in wastewater and seawater. In this study, the contribution of carbon nanotubes (CNTs, single-walled carbon nanotubes) to membrane fouling control and ...

  • Assessment of an ultrafiltration pre-treatment system for a seawater reverse osmosis plant

    The seawater reverse osmosis system requires extensive pre-treatment in order to ensure reliable performance. The conventional pre-treatment system involves dosing of chemicals, which requires frequent monitoring of raw water quality, and also involves adjusting the dosage. Besides being cumbersome, there is a lot of time lag involved in carrying out these measures. This calls for pre-treatment ...
