Special thanks to the City of Rigby, ID and Keller Associates, Inc. for choosing the MOB (Mobile Organic Biofilm) process for an oxidation ditch retrofit!
Installed for increased capacity, cold weather nitrification (as low as 8º C), enhanced phosphorus removal and increased settleability. Sized to handle increased biochemical oxygen demand from 1,200 lbs/day to 3,165 lbs/day in the existing basin.
