A major landfill operator had a leachate that contained elevated levels of BOD, ammonia and arsenic and was not suitable for discharge to a local sewer district. A small pilot system was proposed to examine the ability of elevated DO to “oxidize” the arsenic. The unit demonstrated an incremental reduction of arsenic from .12 PPM to 0.09 PPM while also reducing COD and BOD. Additional testing is proposed and under consideration.
- Supersaturated dissolved oxygen oxidizes various contaminants
- Increases biological activities to breakdown organics
- Reduces BOD, COD, and turbidity
- Minimize and eliminate odors
