Case Study: Yucaipa, CA Upgrades Their Activated Sludge Treatment Plant

The Challenge
In 2007 the Yucaipa Valley Water District in Yucaipa, CA upgraded their Activated Sludge treatment plant to a Kruger AnoxKaldnes Biofilm + Activated Sludge (HYBAS™) process. The plant expansion was driven by an increase in hydraulic loading and a new Total Inorganic Nitrogen Limit that was lowered from 10 mg/L to 6 mg/L.
