Effective removal of disinfection by-products and assimilable organic carbon: An advanced water treatment system

Evaluation of microbial regrowth potential by assimilable organic carbon in various reclaimed water and distribution systems

“…This may be because most of the water reclamation plants investigated here use ozonation in the final treatment step. Typically, AOC in drinking water ranged between less than 10 mg C/L to 200 mg C/L (Charnock and KjØnnØ, 2000;Chien et al, 2007;Kaplan et al, 1992;Lehtola et al, 2002;Liu et al, 2002;Lou et al, 2009;Ohkoushi et al, 2011;Polanska et al, 2005;Soonglerdsongpha et al, 2011;Van der Kooij, 1992) depending on treatment process, seasons, and locations. Our results showed the range of AOC concentrations in reclaimed water was 36e446 mg C/L with median of 316 mg C/L, which was a little higher than the usual range in drinking water.…”

Biologically active carbon filtration for haloacetic acid removal from swimming pool water

“…The removal of HAAs may also benefit from the low concentrations of combined chlorine (0.16 ± 0.16 mg/L) in the pool water. In addition, there were beneficial aspects of the disinfectants' presence, which were the breakup of the recalcitrant organics and production of more assimilable organic carbon (AOC) for the bacteria growth in the BAC medium (Butterfield et al, 2002;Lou et al, 2009).…”

Disinfection and DBPs removal in drinking water treatment: A perspective for a green technology

“…The latter two DBPs follow from big organic molecules being oxidized to smaller molecules, which are more accessible to microbes, plant, and aquatic life as a nutrient reservoir. Oxidized organics are generated while powerful oxidizing chemical products (ozone, permanganate, chlorine dioxide, or hydroxyl radical) are utilized (Guo et al, 2014;Lou et al, 2009;Tian et al, 2014).  Inorganic compounds, like chlorate, chlorite, and bromate ions, produced while chlorine dioxide and ozone disinfectants are utilized (Guo et al, 2014;Lou et al, 2009;Tian et al, 2014).…”
