Title: | Drinking water treatment with recovered flocculant from alumina fabrication process | Authors: | Stefanescu, Mihai Cosma, Cristiana Cristea, Ionut Nitoi, Ines Bumbac, Costel Badescu, Valeriu |

Experimental tests emphasized the efficiency of recovered and purified sodium aluminate for surface water treatment. Three different flocculants (sodium aluminate, classic flocculant, polyaluminum chloride – PAC) at four aluminum doses were tested. Turbidity, total organic carbon (TOC), iron, manganese and sodium indicators were monitored. Similar removal efficiencies have been calculated for turbidity (>99%), iron (>99%), manganese (~80%), aluminum (94–98%) and 58 and 47% for TOC in case of recovered sodium aluminate and PAC, respectively. The application of recovered flocculant proved its efficiency for coagulation-flocculation treatment phase, which mean that could be used instead classical flocculant without any secondary pollution effects. Recovered sodium aluminate is a good flocculant for drinking water treatment with many other applications in the field of wastewater treatment. |
