Caldwell Wastewater Treatment Plant Improvements
IMCO is upgrading the industrial wastewater treatment plant at Darigold’s Caldwell butter plant. These improvements will allow their discharged waste to remain compliant with environmental requirements.
IMCO crews demolished an existing storage building and constructed a new dissolved air flotation (DAF) treatment building, a second glass lined steel equalization tank, and pre-engineered metal building.
The DAF unit provides chemical and physical treatment of the industrial waste. Conventionally treatable waste is discharged into the sewer system while solids are removed and pumped into trucks that dispose of the solids generated by the development of Darigold’s adjacent butter facility.
