Sarah Onofrio
Account Executive @Brenntag North America
My chemical sales career began in 2007 with Brenntag Northeast. In 2010 I went to work for PVS, a premier manufacturer of high quality iron salts used for coagulation in water treatment facilities. I completed my University of Sacramento water/waste water treatment plant operations volume 1 courses during this time. I spent 6 years focusing on mostly municipal plants with an emphasis on improving TOC removal in drinking water facilities and phosphorous removal in waste water treatment plants. I also worked extensively on ferric/polymer blend applications in an effort to reduce coagulant dose rates, pH adjustment feed rates and sludge generation. The past 4 years I’ve been back in chemical distribution with a water treatment concentration working with industrial plants in addition to municipalities. I especially enjoy coagulant and polymer applications in industrial waste water facilities and I always like to encourage plants to put me to work jar testing.
