The use of coagulation and Fenton oxidation was studied for total organic carbon (TOC) and silica removal from SAGD water at 80oC and 22oC and two different concentrations replicating the stream feeding the warm lime softening unit and the blowdown of the once through steam generator (OTSG). Coagulation was carried out by the addition of FeCl3, Al(NO3)3 and Ca(NO3)2. The results showed that Fe(III) salt outperformed Al(III) and Ca(II) salts. A two-stage addition of 2.5 g FeCl3 per g TOC intermediated by a filtration unit resulted in approximately 72% TOC removal and more than 80% Si removal while maintaining low solid waste. It is believed that silica removal was governed by the resultant pH, whereas TOC removal was accomplished through localized enmeshment coagulation. Fenton Oxidation is proposed to further treat the filtrate obtained from the second stage Fe(III) coagulation. An additional 10% TOC removal could be achieved at 7 times lower H2O2 dose in the presence of Fe2+ or Fe0 reagent. Moreover, Advanced Fenton Process resulted in high Si removal as a consequence of adsorption onto Fe(OH)3 precipitate, which formed at the natural equilibrium pH of the system.
