Biological Wastewater Treatment C. P.L. Grady

€ An engineering firm hired by Auburn to clear the way for the city to accept wastewater from gas drilling has concluded the city's wastewater treatment plant can't handle it. Feb 24, 2014 - This webinar will introduce various biological treatment techniques for treating water and wastewater. How are these used in wastewater treatment? Feb 26, 2014 - 2008) and offer efficient removal of wide range of pollutants in wastewater treatment. We will discuss the following: What is bacteria? Mar 14, 2012 - This is where things started getting interesting. MBR technology is actually a hybrid system, using both biological treatment and mechanical microfiltration to clean wastewater. Feb 15, 2014 - Wastewater treatment plants may actually increase spread of antibiotic resistance in bacteria — a study of two treatment plants in Guandong Province (southeastern China) process (UV and chlorination) could significantly reduce the number of bacteria, but percentage of the resistant bacteria, resistance frequency for each antibiotic, MAR index and detection rate of the plasmid-mediated resistance genes were all found increasing in the effluents of biological units. In addition to In a pilot program sponsored by the German Federal Environmental Foundation (DBU), this smart measurement method is to be utilized for the first time in existing wastewater treatment plants. Apr 8, 2014 - The aim is to supply oxygen more efficiently to the microbes that are used in biological treatment stages. Feb 8, 2012 - Many WWTPs now employ a process that converts this ammonia to atmospheric nitrogen, but a major byproduct of this process is N2O. Sep 25, 2013 - Ardern and Lockett, who invented the activated sludge process, first used the term, activated sludge, in 1914. Kenny Keel, Hillsborough Town Engineer and Utilities A trash removal stage at the beginning of the process has also been implemented, and upgrades have been made to the biological treatment basins. May 19, 2010 - However, the authors of this book are convinced both that we must learn to develop and continue to promote water recycling systems and also that biological wastewater treatment processes play a highly important role. The firm's study “Chloride is already high in our waste stream, and adding the gas well water that's got chloride in it would possibly create issues with our biological process that nitrifies the water, that converts ammonia to an inert form,” said Douglas Selby, Auburn city manager. Such efficiency speeds up the purification process and saves energy. Apr 17, 2014 - At a project cost of $19.8 million, the expanded and renovated Hillsborough Wastewater Treatment Plant is more efficient and environmentally friendly, coming into compliance with the more stringent state rules.
