Good morning ladies and gentlemen! My name is Sarah Hubbell, I’m the Director of Technology for Entex, we are a full service provider of Integrated Fixed-film/Activated sludge and related systems, which includes both the BioPortz moving media and an alternative fixed media called BioWeb. This morning I’m going to talk all the different options that are available to engineers who are interested in designing an IFAS system for wastewater treatment.
So here’s a sneak preview of what I’m going to cover in this short talk.
