Experimental Evaluation Of Friedel’S Salt For Chloride Removal In Road Salt-Impacted Stormwater And Lakes, Marwan Alhinaai

Masters Theses

Road salt (e.g., NaCl) application in cold-temperature regions has increased Cl- concentrations in freshwater. Removing Cl- from water is challenging because it’s highly soluble. This paper is the first to demonstrate and characterize the removal of Cl- from stormwater by Friedel’s salt (Ca4Al2(OH)12Cl2(H2O)4) precipitation (FSP), achieved by adding calcium oxide (CaO) and sodium aluminate (NaAlO2). Laboratory tests were done on Cl- removal with FSP using a range of Ca/Al/Cl ratios in deionized (DI) water and in stormwater samples impacted by road salt. Even the lowest doses resulted in significant removal of Cl- with maximum removal rates for comparable Ca/Al/Cl ratios …
