Aerators In Waste Ponds At Chemical Plant

Hahnville, Louisiana, USA

In industrial waste aeration ponds, liquid waste is mixed with air by bubblers or paddles, facilitating oxidation or microbial action that helps break down or neutralize the waste. This chemical plant makes derivatives used in products ranging from cosmetics to plastic wrappings to paint additives. One person died at this plant in 1998, suffocated when the area where he was working was filled with nitrogen.
