  • Comparative study on metal ions adsorption on a low cost carbonaceous adsorbent kinetic equilibrium and mechanistic studies

    Wastewater generally contains toxic inorganic and organic pollutants. Inorganic pollutants consist of mineral acids, inorganic salts, finely divided metal compounds, trace elements, cyanides, nutrients and organometallic compounds. Some of the trace elements play essential roles in biological processes, but at higher concentrations, they may be toxic to the biota; they disturb the biochemical ...

  • Separate As(V) from solution by mesoporous Y-Al binary oxide: batch experiments

    Contaminant arsenic(V) has been regarded as one of the top-priority pollutants to remove from water. In this contribution, different mesoporous Y-Al binary oxides were prepared by the wet impregnation method via varying the molar ratio of Y/Al in the range of 0.029 to 0.116. The manufactured materials were employed as adsorbent to separate arsenic(V) from water. The adsorbent was characterized ...

  • Response surface methodology approach for the optimisation of adsorption of hydrolysed polyacrylamide from polymer-flooding wastewater onto steel slag: a good option of waste mitigation

    Wastewater produced from polymer flooding in oil production features high viscosity and chemical oxygen demand because of the residue of high-concentration polymer hydrolysed polyacrylamide (HPAM). In this study, steel slag, a waste from steel manufacturing, was studied as a low-cost adsorbent for HPAM in wastewater. Optimisation of HPAM adsorption by steel slag was performed with a central ...

  • Activated Carbon Applications Excel at PCB Removal

    TIGG’s GAC adsorption equipment is used to remove PCBs from groundwater. For more than 50 years, polychlorinated biphenyls (PCBs) were commonly used in industrial materials including, caulking, cutting oils, inks, paints and as dielectric fluids in electrical equipment such as transformers and capacitors. Concerns over health effects led to a North American ban of ...

  • Low Energy Biological Nitrogen Removal by Cation Exchange, Thin Film Oxygen Transfer, and Heterotrophic Nitrification in Sequencing-Batch, Packed-Bed Reactors

    Sustainable solutions for biological nitrogen removal (BNtR) in wastewater require new treatment process concepts to lower energy requirements. A novel configuration of six packedbed, flood and drain (PFAD) reactors were used in a pilot study to remove nitrogen from a manufactured wastewater comprised of urea, cheese whey, and well water. The reactors operated in a sequencing-batch manner in ...

    AquaBlok, Ltd., a manufacturer of innovative clay-based composite materials, has announced the introduction of a new organoclay product that provides for ease of delivery and improved performance of this well known remedial material technology. What the company calls 'AquaBlok+ORGANOCLAY' will preferentially adsorb and sequester a wide range of hydrocarbon and petroleum based contaminants. It can ...

  • Hydrocarbon evaporative emissions & control for automotives

    Even the cleanest and most efficient vehicle on the market today still pollutes the air and otherwise damages the environment. Motor vehicles emit several noxious pollutants which vehicle emissions standards are designed to regulate. Vehicles generally emit Hydrocarbons (HC), Carbon monoxide (CO), Nitrogen oxides (NOx) and Fine airborne particulate matter (PM) as pollutants that require control. ...

  • The Many Uses of Activated Carbon

    Activated carbon is processed to have small, low-volume pores that increase the surface area available for adsorption. It has applications in the medical, environmental and energy realms, among others. Since 1962, ASTM Committee D28 on Activated Carbon has developed standards that play a pre-eminent role in how activated carbon is used. A D28 ...

  • Properties and Behavior of Inorganics in Contaminated Soil

    Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...

  • Non-woven electrostatic media for chromatographic separation of biological particles

    The filtration and separation of biological particles has been estimated as 40% of the cost in the manufacture of pharmaceuticals. Liquid chromatography that is the principal method for separating biological particles uses a permanent phase of ultrafine adsorbent particles such as porous silica or resin spheres with particle sizes down to about 1 micron. Speed and resolution are two competing ...
