Chemical-Free Arsenic Removal for Small-Scale Potable Water Treatment Systems

This research project is a joint venture between Mainstream Water Solutions Inc.,the University of Regina Engineering Department and the national Research Council of Canada (NRC) partially funded by Communities of Tomorrow, University of Regina, and the Social Sciences and Humanities Research Council of Canada (SSHRC). 

OBJECTIVE:
The objective is to enhance the arsenic removal capabilities of slow sand filtration systems under certain water quality conditions through the addition of iron (zero valent iron filings).  The proposed technology is targeted to small utilities, therefore, the Mainstream BioFiltration system has been chosen for this project as it excels at addressing rural water treatment needs.  The treatment process must remain simple, chemical-free and sustainable.   

RESEARCHERS:
Ann Gottinger, B.Sc.ES, MASc.EVSE (candidate), Dr. Dena McMartin (supervisory), Dr. Brett Moldovan (collaboration)

RESEARCH PLAN:
The study is currently underway with batch and column studies being conducted.  Subsequent pilot-scale studies will take place in early 2008 at two local communities.
