Book Description
Natural organic matters (NOM) interact with disinfectants and produce disinfection by-products (DBPs). One of the best available technologies to remove NOM from water to reduce DBPs formation is adsorption with activated carbon. In this study, the removal of NOM from pond water was studied using powder activated carbon (PAC), and the granular activated carbon (GAC) generated from Corner Brook Pulp and Paper (CBPP) fly ash as raw material. PAC was used in batch tests and water pH, temperature, and volume was considered as variables to determine optimized conditions for NOM removal applying response surface method (RSM); it was concluded that water pH and volume have significant effects on NOM removal. CBPP was combined with bitumen as a binder to produce GAC. Effect of binder to carbon ratio, calcination and steam activation temperature, the temperature increasing rate, and steam activation time were studied to produce GAC with high BET surface area and efficient hardness. Granules with 30:70 binder to carbon ratio, calcinated at 750°C, activated at 950°C for 3 hours with 15°C/min of heating rate were found to be ideal for GAC production for NOM removal. Column tests for NOM removal were conducted using produced GAC. Results indicate that the produced GAC is effective for 60% NOM removal. Follow-up chlorination experiments illustrate that the formation of DBPs (THMs and HAAs) were significantly reduced. Used GAC was regenerated using RSM design at different regeneration temperature, time, and steam flow. The results show that regeneration at 916°C for 43 minutes under 350 mL/min of steam would lead to optimum regeneration conditions.

Book Description
In this study, the removal of NOM from surface water intake and reduction of THMs and HAAs in the water distribution system were investigated in the Pouch Cove community water system using granular activated carbon (GAC) developed from the Corner Brook Pulp and Paper (CBPP) fly ash. [...] The treatment of the ash during extraction of carbon will also detoxify the waste residue causing less impact on the groundwater and environment around the landfill. [...] The effects of different activation temperatures and different activation time lengths were investigated in the previous studies using powdered activated carbon (PAC) and found that the activated carbon (AC) generated from CBPP ash waste has a great potential to resolve the problem of disinfection-by- products (DBPs) in the drinking water systems in rural in the province (Shadbahr, et al., 2017, Z [...] Calcination and activation temperature, time, and heating rate will impact the chemical nature of the binder and quality of the produced GAC (Rubio et al., 1999). [...] The slope (S) and the y-intercept (I) of the plot were used to calculate vm and the BET constant (Mofarrah, 2014).

Book Description
"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"--
