As one of the largest beverage producers in the food service industry, Coca Cola Corporation has bottling plants worldwide. A large number of beverages are bottled in the Wilsonville plant; both sugar and non suger beverages. The facility also houses a reclaim/recycle facility for beverages which dates have expired. This crushing operation and the large number of product changes created a highly variable flow rate, sugar content, and pH. These large variations caused excursions outside of pretretment permit limits and created operational issues at the local municipal treatment plant.

• Design/build of a pretreatment and equalization system to minimize excursions
• Storage capacity to allow for equalization of the discharge to minimize the impacts to the local municipal treatment plant by creating a 7-day 24-hour constant flow
• Treatment for pH control and solids removal (fat, oils, greases and suspended solids)

• Two 50,000-gallon stainless steel tanks with aeration for equalization
• Two stage pH adjustment for pH control
• Coagulation and flocculation to aid in solids removal
• Dissolved air flotation for solids removal
• Effluent monitoring with automatic recirculation for out of permit discharges including pH and flow
