  • The SEWGS technology is the combination of the water gas shift reaction with the adsorption of carbon dioxide on a solid material. (wikipedia.org)
  • Traditional technologies require employing two water gas shift reactors (a high temperature and a low temperature stage) in order to get high conversions of carbon monoxide into carbon dioxide with an intermediate cooling stage between the two reactors. (wikipedia.org)
  • The SEWGS technology is based on a multi-bed pressure swing adsorption (PSA) unit in which the vessels are filled with the water gas shift catalyst and the CO2 adsorbent material. (wikipedia.org)
  • The Rice University team discovered a new catalyst that can turn nitrite pollutant waste into ammonia, a compound mostly used as fertiliser and household cleaner. (aquatechtrade.com)
  • The aim of the project consortium coordinated by KWR Watercycle Research Institute (NL) is to further develop and demonstrate technologies which are suitable to eliminate trace organics from both surface waters and wastewaters and to analyse their performance. (kompetenz-wasser.de)

  • In several instances, records show, operators did not meet requirements to identify old or abandoned wells near injection sites until waste flooded back up to the surface, or found ways to cheat on tests meant to make sure wells aren't leaking. (nbcnews.com)

  • In order for current and future Chicagoans to see the river system as the City's second waterfront, they must first trust the health and safety of the water. (chicagoriver.org)
  • These disparities are also important in terms of health risks associated with poor water safety and may be further aggravated by the impact of climate change. (who.int)
  • Millennium Development Goal Target 7.C captures the need for access to safe drinking-water in a broad development framework that also includes public health. (who.int)
  • The overloaded wastewater systems then threaten to back up into homes, so cities will dump the sewage without treating it to avoid such backups. (startribune.com)
  • Secondary treatments use accelerated microbiological growth to remove organic pollutants. (sigmaaldrich.com)
  • Many communities along the river are home to industries that pollute the surrounding air and water. (chicagoriver.org)
  • EPA Application Form 2E - This form is for facilities that discharge only non-process wastewater (e.g., discharges of sanitary wastes, cafeteria wastes and noncontact cooling water). (tn.gov)
  • Previous studies on heavy metals of urban wastewater systems have focused on long-term (weekly or seasonal) variations, while only few studies investigated short-term (daily) variation to capture potential bulk discharges. (lu.se)
  • This reduction in violations advances EPA's strategic plan goal to ensure clean and safe water for all communities. (wwdmag.com)
  • Five years ago, EPA set an ambitious goal for cutting the rate of significant noncompliance with Clean Water Act permits in half," said Larry Starfield, acting assistant administrator for EPA's Office of Enforcement and Compliance Assurance. (wwdmag.com)
  • Underlying this achievement is EPA's 2015 CWA rule that requires all facilities to electronically report water discharge pollutant monitoring data to EPA and the states. (wwdmag.com)
