Polyaluminum chloride coagulation in drinking water treatment
Dissolved organic matter, DOC [mg C/L], is a representative parameter for the content of organic matter in natural waters. Along the A254 absorbance as a measure of organic compounds determined at X = 254nm UV [cm'1], DOC underlies the calculation of SUVA (Specific Ultraviolet Absorbance) = A25...

| 520 | 3 | |a Dissolved organic matter, DOC [mg C/L], is a representative parameter for the content of organic matter in natural waters. Along the A254 absorbance as a measure of organic compounds determined at X = 254nm UV [cm'1], DOC underlies the calculation of SUVA (Specific Ultraviolet Absorbance) = A254/DOC x 100 [L-m '-mg'1]. SUVA can be used to describe the composition of the water in terms of hydrophobic / hydrophilic character. The study results are presented in the coagulation process with pre-hydrolyzed aluminum salt, as a polyaluminum chloride (PAC1), a simple salt of Al, as an A1 sulfate (Alum), applied to surface water intended for drinking water. From SUVA values DOC removal efficiency in the coagulation process is estimated. SUVA = 2-4 estimated efficiencies of 25-50% removal in DOC. When using PAC1, DOC removal efficiency is within the range of 27-53%, and slightly lower when using Alum. SUVA values <2 indicate DOC removal efficiencies <25%. DOC removal efficiencies obtained from the use of Alum are within the range 5.6-8.4% and those obtained when used as coagulation agent PAC1 are in the range 20.8-23.8%. | |
