The Leopold elimi-NITE® 2.0 denitrification system is a gravity, deep bed, mono-media sand filter designed to remove nitrate and phosphorous to meet stringent effluent discharge water requirements without increasing the Total Suspend Solids (TSS) and Biochemical Oxygen Demand (BOD).
The Leopold elimi-NITE® 2.0 denitrification system is a gravity, deep bed, mono-media sand filter designed to remove nitrate and phosphorus to meet stringent effluent discharge water requirements without increasing the Total Suspend Solids (TSS) and Biochemical Oxygen Demand (BOD). As a part of the denitrification system, Leopold has developed and implemented a proprietary gas release cycle that automatically determines the optimum time to release the nitrogen gas from the filter. At the same time, phosphorus, in solid form, is removed along with other solids. In a recent performance test at a Maryland wastewater treatment plant, the system demonstrated the ability to achieve filter effluent nitrate <0.5 mg/L, phosphorus <0.2 mg/L and TSS <5.0 with no increase in BOD at design loading rates.
