The New York State Center for Clean Water Technology plans to upgrade aging septic systems on Long Island with new nitrogen removing biofilters, or NRBs, that remove harmful contaminants at a higher rate.
Dr. Chris Gobler is the center’s director.
“If you attach an NRB to the end of that wastewater, we re reducing it by more than 60% and most importantly, in all cases, the effluent of our NRBs is less than one microgram per liter. That is the New York State drinking water standard. So the water is coming in above the standard, it s going through the NRB, and it s coming out below the standard,” Gobler said.
