Chobani MBR System has continually met discharge requirements since startup
DESCRIPTION
Agro Farma, now known as Chobani had a failed lagoon that was overloaded and had a consent order from NYDEC because they were discharging to a tributary of Susquehanna river and had to meet Chesapeake Bay water authority regulations. Since it was under consent order, the selection of MBR technology all the way to execution and startup happened in a fairly short duration, less than a year from Spring 2010 to Spring 2011. The initial design was for quarter of a million gallon per day but there have been two subsequent expansions up to 1.1 mgd. The waste includes dairy waste and does not include whey from yogurt.
