This book was released on 2015 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The addition of chlorine disinfectant to drinking water during the treatment process results in the formation of disinfection by-products (DBPs). The United States and several other nations regulate for DBPs in drinking water because studies have linked exposure to these compounds to increased incidence of cancers as well as birth and developmental defects. Incorporation of activated carbon(AC) into the drinking water treatment process may reduce the formation of DBPs through the adsorption of natural organic matter (NOM) precursors and formed DBPs. The goal of this research project is to investigate how AC can be better used by small-scale drinking water plants as a feasible option for reducing the DBPs formed in their systems, which would allow them to consistently achieve compliance with the Environmental Protection Agency’s latest regulation Stage 2 D/DBP Rule. This research compared the factors of AC particle size, carbon source material, and concurrent coagulant addition in NOM sorption experiments. Although concurrent chemical addition and carbon source had no significant differences on AC performance, the performance of powdered activated carbon (PAC) was notably greater than granular activated carbon(GAC). Characterization of NOM in source water showed preferential adsorption of hydrophilic NOM compounds onto the AC. Finally, a pilot studied was designed to investigate the potential of granular activated carbon (GAC) to adsorb formed DBPs before entering the distribution system.
Book Synopsis Activated Carbon by : Zaid K. Chowdhury
Download or read book Activated Carbon written by Zaid K. Chowdhury and published by American Water Works Association. This book was released on 2013 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Many books have been written about granular activated carbon. Some focus on the theory of performance and removal mechanisms while others focus on design features. This book focuses on solutions. It describes the challenges facing water providers to provide safe water that is acceptable to their customers, utility experiences using activated carbon, activated carbon applications, and design and procurement approaches. The appendices include detailed case studies and a life-cycle assessment demonstrating favorable sustainability considerations for activated carbon when compared to other treatment technologies. Never before has all of this information been together in one location. The what, why, and how of activated carbon are connected in this book and demonstrate why this treatment technology has maintained its status as an integral treatment technology in the quest for pure water over millennia"--

Book Synopsis Activated Carbon for Water and Wastewater Treatment by : Ferhan Cecen
Download or read book Activated Carbon for Water and Wastewater Treatment written by Ferhan Cecen and published by Wiley-VCH. This book was released on 2011-10-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides comprehensive coverage of technologies which integrate adsorption and biological processes in water and wastewater treatment. The authors provide both an introduction to the topic as well as a detailed discussion of theoretical and practical considerations. After a review of the basics involved in the chemistry, biology and technology of integrated adsorption and biological removal, they discuss the setup of pilot- and full-scale treatment facilities, covering powdered as well as granular activated carbon. They elucidate the factors that influence the successful operation of integrated systems. Their discussion on integrated systems expands from the effects of environmental to the removal of various pollutants, to regeneration of activated carbon, and to the analysis of such systems in mathematical terms. The authors conclude with a look at future needs for research and develoment. A truly valuable resource for environmental engineers, environmental and water chemists, as well as professionals working in water and wastewater treatment.
Book Synopsis Application of Biologically Activated Carbon for Treatment of Sulfide-laden Groundwater by : Jessica Cormier

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small-system water purveyors must overcome many challenges to provide an adequate and safe water supply to its consuming public. This dissertation reports on research related to the application of biologically activated carbon (BAC) media filters for the treatment of well water to remove disinfection by-product (DBP) precursor matter, measured as dissolved organic carbon (DOC), at two treatment plants serving a small community water system. Four research questions were investigated individually in discrete, yet interconnected studies at two water treatment facilities processing groundwater that contained hydrogen-sulfide (~1.2 mg/L) and dissolved organic carbon (~2.0 mg/L). The first study revealed that BAC filters operated at the pilot-scale removed 50% of DOC regardless of carbon type or loading rate. A second study showed that GAC media replacement frequency, when transitioned from adsorption mode to biological-mode, would extend media change-out from 4 times per year to once to once every 2.5 years of service, providing a total savings of $40,000 per facility per operational year. A third investigation used genetic sequencing and quantitative polymerase chain reaction (qPCR) techniques using universal primers to identify the microbial communities within GAC filters operating in biological mode. Both sulfur-reducing and sulfur-oxidizing bacteria were identified as the predominant groups colonizing the GAC contactors. Genotyping of the different carbon types showed similar community composition; however, differences in the phylogenetic diversity of the samples were evident. A fourth study demonstrated that tray aerators could be integrated into a BAC process to decrease total trihalomethane DBPs entering the water distribution system.

A GridBee® spray-aeration process was place into DWS's Lower Kula water system's Brooks ground storage tank in February of 2013. In March of 2015 the second DBP control technology, granular activated carbon (GAC), was integrated into DWS's Pi'iholo surface water treatment plant. To investigate the integration effectiveness of GAC and spray-aeration into a water system for DBP control, DBP data was gathered from the system between August of 2011 and August 2016, and analyzed relative to cost and performance.
