Affordable Water Filtration Technology for Small Rural Communities /

Addressing these challenges will require both extensive laboratory research and field pilot studies to evaluate the effectiveness of the treatment process and the seasonal variations of NOM levels through the year, which are also the purposes of the study. [...] According to the results of chlorination tests, it is obvious that the higher amount of hydrophobic fraction in New-Wes-Valley resulted in the higher amount of DBPs including THMs and HAAs with the concentrations of 1310 mg/L and 666 mg/L. [...] The big difference in the TOC removal and UV deduction results implied that some of the organic compounds in the water sample cannot absorb UV light at the wavelength of 254 nm. [...] When the water enters the column, and passes through the carbon barrier, the natural organic matter in water can be adsorbed by the activated carbon so that the formation of DBPs can be avoided or mitigated. [...] For Sunnyside and New-Wes-Valley, the column effluent was sampled at the 1st, 2nd, 3rd, 6th, 12th and 24th hour for the analysis of TOC, and the 6th, 12th and 24th hour for the analysis of UV254.
