As the drainage basin to 85 million people, the Baltic Sea has faced considerable environmental strain for many years. Updated regulations to reduce levels of phosphorous and nitrogen prompted the Central Wastewater Treatment Plant in Saint Petersburg, Russia, to install new top-entry agitators in its aeration basins. By optimizing thrust and bulk flow, the updated plant now combats pollution by treating 400 MGD of wastewater while keeping energy costs to a minimum.
