  • Removal of humic substances using solar irradiation followed by granular activated carbon adsorption

    This study proposed a new method using freely available sunlight and granular activated carbon (GAC) adsorption for enhanced removal of humic substances (HS). Experiments were carried out under natural sunlight conditions in winter and summer. A parabolic solar collector (PC) was applied to concentrate solar energy. HS were characterized by UV254 absorbance, dissolved organic carbon (DOC) ...

  • A technical note on performance testing of a solar box cooker provided with sensible storage material on the surface of absorbing plate

    A box type solar cooker having a double glass cover and a plane mirror reflector has been tested for its thermal performance. In the present study, performance of solar box cooker has been compared by using two different sensible heat storage materials (sand and granular carbon). By using these materials as a mixture and spread it over absorber tray in the form of thin layer and fully packed with ...

  • The evolution of organic character in a drought- and flood-impacted water source and the relationship with drinking water treatment

    A pilot-scale research investigation examining treatment technologies including coagulation, ion-exchange, activated carbon and membrane filtration and their impact on water quality coincided with a period of extensive variability in source water character. Distinct water quality periods as a result of extreme climatic conditions from drought to flood were observed and the natural organic ...

  • Performance of a GAC and ultrafiltration hybrid process under high humidity and temperature conditions

    The performance of a granular activated carbon (GAC) and ultrafiltration (UF) hybrid process and changes in UF membrane properties were studied. This hybrid process reduced total organic carbon by 59 ± 12% and UV absorbance (UV254) by 88 ± 31%, with GAC accounting for 93 and 98% of total reduction, respectively. Selected pharmaceuticals and personal care products were reduced by 32–92% during the ...

  • Membrane fouling mitigation by activated carbon addition in activated sludge filtration

    Activated carbon (AC) was added into the activated sludge to alleviate membrane fouling during sludge microfiltration. The fouling mitigation profiles were evaluated at different AC sizes and doses by a single-fibre microfiltration system. It was found that the granular AC added in the sludge suspension can absorb the organic substances in the sludge in a certain level, including biopolymer ...

  • Assessment of water treatment processes: detailed organic matter characterisation and membrane fouling indices at the Loddon Water Treatment Plant, Victoria, Australia

    Recent advances in membrane technology have led to its broad application, and reverse osmosis (RO) systems now represent the fastest growing segment of the desalination market. Its performance is hindered by membrane fouling. In this study pre-treatment methods to reduce RO fouling were investigated including flocculation, adsorption and ion exchange. Detailed organic characterisations were made ...

  • LiquiSorb 200 saves time and money before the rubber hits the road

    Problem In tire manufacturing there is much more to the finished product than just rubber. Tire chords, a by-product of the manufacturing process, are coated with a proprietary dip solution that acts as a flexible adhesive/bond in tires. This dip solution has an extremely high concentration of solids in water, making traditional wastewater treatment techniques less effective, extremely slow, and ...

  • It’s Time to Rethink Cooling Tower Filtration

    ABSTRACTThe dissipation of ambient or process heat in large HVAC systems, manufacturing facilities, power generation plants, refineries, metal mills and forges, chemical plants and food processors is most often accomplished by cooling towers. These simple structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere. The bane of cooling ...

  • City Water International explains The Basics of Water Filtration

    The Basics of Water Filtration Most of us know that filtered water is healthier than tap water because of its purity, but how does water filtration work? The basic principle is that filtered water has passed through a filter which removes contaminants through one of several methods, depending on the type of filter. Most water purification systems work in one of three ways ­ by running water ...

  • Cleaning and maintenance management march 2002

    While the health risks associated with fluid waste have been known for decades, it wasn’t until the introduction of AIDS into our society that infection control practices and an awareness of the vulnerability to healthcare workers, including custodians, to exposure of bloodborne pathogens, including Heptatities B, became a major concern. Today, a myriad of regulations govern workers’ ...


  • Preparing Spill Response

    Whether a company stores, uses, or transports hazardous materials (hazmat), there is always the potential for a chemical spill. And beyond regulatory requirements that all employees are trained to handle chemical spills, it is also the responsibility of an owner to keep employees safe when doing so. Below are answers to some of the most commonly asked questions about emergency response spills, as ...
