Bottling Plant

Shoreline Stabilization

Issue:  A bottling company in Minnesota discharges some 6,000 gallons per day of wash   down water with a COD of 40,000 – 70,000 mg/L. The material is too strong for the local wastewater treatment plant to process, so it must be trucked off site.

Action:  Design/build an aerobic onsite treatment system using micro bubble aeration to reduce strength to less than 1,000 mg/L BOD5 and allow local discharge. The system includes bioreactors, automatic pH adjustment, nutrient addition, flow equalization, sludge handling, online controls and monitoring, and continuous effluent monitoring and sampling.

Results:

COD: 817 mg/l
CBOD: 245 mg/l
TSS: 132 mg/l
