What equipment do I need to perform a vacuum filtration?

by Camlab Limited  (Jul. 17, 2015)

Filtration under vacuum, also known as Büchner filtration, is commonly used to isolate the solid precipitate from a solution. This technique is used in syntheses, for example when a reaction has yielded a solid, or in analyses including gravimetric analysis of suspended solids. ...

Well-to-Wheels Greenhouse Gas Emissions of Canadian Oil Sands

by GLOBE Foundation  (Jun. 25, 2015)

Are greenhouse gas emissions from Canada’s oil sands higher than those from conventional oil? Apparently yes, according to a new study funded in part by the U.S. Department of Energy. It says oil from Canada’s oil sands produce greenhouse-gas emissions that average 20% more than from oil from conventional U.S. crude. The study ...

Toxicokinetics of perfluorooctane sulfonate (PFOS) in rainbow trout (Oncorhynchus mykiss)

by John Wiley & Sons, Ltd.  (Sep. 3, 2015)

Rainbow trout (Oncorhynchus mykiss) confined to respirometer‐metabolism chambers were dosed with perfluorooctane sulfonate (PFOS) by intra‐arterial injection and sampled to obtain concentration time‐course data for plasma, and either urine or expired water. The data were then analyzed using a two‐compartment clearance‐volume model. Renal and ...

Cities are finally treating water as a resource, not a nuisance

by Ensia  (Sep. 1, 2015)

From Houston to Melbourne, the surprising ways urban areas are dealing with water woes Memorial Day barbecues and parades were thwarted this year in Houston when a massive storm dumped more than 10 inches of rain in two days, creating a Waterworld of flooded freeways, cars, houses and businesses, leaving several people dead and hundreds in need ...

Removal of hydrocarbons from synthetic road runoff through adsorptive filters

by IWA Publishing  (Aug. 19, 2015)

Compact filter systems, which are installed to significantly reduce the load of pollutants from road runoff, are very promising treatments for urban runoff. The objective of this research was to evaluate the effectiveness of activated carbon, activated lignite, zero valent iron, exfoliated graphite, amorphous ferric hydroxide, and activated ...

Total and methylmercury partitioning between colloids and true solution: From case studies in sediment overlying and pore waters to a generalized model

by John Wiley & Sons, Ltd.  (Aug. 4, 2015)

Tangential flow ultrafiltration was used to determine the partitioning of total mercury (THg) and monomethyl‐mercury (MMHg) between colloids and true solution in sediment overlying (OW) and pore waters (PW) collected in Lake Geneva (Switzerland/France), Venice lagoon (Italy), and Baihua reservoir (China). Overlying water and PW spanned ...

Decentralized peri-urban wastewater treatment technologies assessment integrating sustainability indicators

by IWA Publishing  (Jul. 16, 2015)

Selection of treatment technologies without considering the environmental, economic and social factors associated with each geographical context risks the occurrence of negative impacts that were not properly foreseen, working against the sustainable performance of the technology. The principal aim of this study was to evaluate 12 technologies ...

Aquifer recharge with reclaimed water: life-cycle assessment of hybrid concepts for non-potable reuse

by IWA Publishing  (Jun. 26, 2015)

Aquifer recharge with reclaimed water is a promising means to store and supply on demand reclaimed water of high quality for further non-potable reuse. The reuse applications may include indirect agricultural or landscape irrigation, saltwater intrusion barriers, subsidence mitigation or aquifer replenishment. As an alternative to high-pressure ...
