Most nitrogenous materials in natural waters tend to be converted to nitrate, so all sources of combined nitrogen, particularly organic nitrogen and ammonia, should be considered as potential nitrate sources. Primary sources of organic nitrates include human sewage and livestock manure, especially from feedlots. The primary inorganic nitrates that may contaminate drinking water are potassium nitrate and ammonium nitrate, both of which are widely used as fertilizers. According to the Toxics Release Inventory, releases to water and land totaled more than 112 million pounds from 1991 through 1993. The U.S. Environmental Protection Agency (EPA) has found nitrate in excess of 10 mg/L in over 800 small, rural groundwater systems.
The water supplies most vulnerable to nitrate contamination are in agricultural areas and in well waters having a close or hydraulic relationship to septic tanks. Only 10 percent of the wells surveyed in a recent U.S. EPA groundwater study, however, had nitrate levels above 20 mg/L. High nitrate is the most frequent reason for shutting down wells in the United States, making the case for facilities to prioritize nitrate removal.
For treating and removing nitrate from water, AdEdge offers a line of packaged, pre-engineered APU systems using ion exchange or the biottta® process, which leverages naturally occurring microorganisms for wellhead treatment of contaminants like nitrate.
Nitrate Removal System Features & Benefits
- High-efficiency water conservation for minimizing waste
- High-efficiency salt usage for conserving OPEX
- Automated bypass with proportioning valve for consistency in reaching targeted water quality
- Countercurrent regeneration to limit contaminant leakage and allows for lower salt usage
- Water/brine recovery system
Our biottta® solutions are fixed-bed, dual stage biotreatment systems that cultivate a robust environment for microbiological organisms to destroy contaminants or reduce elements to simple non-harmful forms. Developed specifically for drinking water applications, the fixed-bed treatment process consistently addresses contaminants at low levels, intermittent or fixed operation, and the dual-bed assimilates a complete packaged biotreatment plant with a dependability required for protecting public health.
