2. Nitrate - Wikipedia

   en.wikipedia.org/wiki/Nitrate

   Through the Safe Drinking Water Act, the United States Environmental Protection Agency has set a maximum contaminant level of 10 mg/L or 10 ppm of nitrate in drinking water. [ 18 ] An acceptable daily intake (ADI) for nitrate ions was established in the range of 0–3.7 mg (kg body weight) −1 day −1 by the Joint FAO/WHO Expert Committee on ...

3. Nitrification - Wikipedia

   en.wikipedia.org/wiki/Nitrification

   The conventional removal is nitrification, followed by denitrification. The cost of this process resides mainly in aeration (bringing oxygen in the reactor) and the addition of an external carbon source (e.g., methanol) for the denitrification. Nitrification can also occur in drinking water.

4. Aerobic denitrification - Wikipedia

   en.wikipedia.org/wiki/Aerobic_denitrification

   Lingering nitrate in drinking water poses a plethora of health risks, and both nitrate and nitrous oxide have major environmental impacts. [6] [7] Some hazards include, carcinogenic nitrite ions in drinking water, or eutrophication caused by oxidized nitrogen seeding algal blooms.

5. Denitrification - Wikipedia

   en.wikipedia.org/wiki/Denitrification

   These include methods that can destroy nitrogen compounds, such as chemical and electrochemical methods, and those that selectively transfer nitrate to a concentrated waste stream, such as ion exchange or reverse osmosis. Chemical removal of nitrate can occur through advanced oxidation processes, although it may produce hazardous byproducts. [38]

6. Ion exchange - Wikipedia

   en.wikipedia.org/wiki/Ion_exchange

   Selective removal: Ion exchange resins can be designed to selectively remove specific ions from water. High efficiency: Ion exchange processes can achieve high removal efficiencies for targeted ions. Regenerability: Ion exchange resins can be regenerated multiple times by flushing them with a regenerating solution, extending their lifespan and ...

7. Eutrophication - Wikipedia

   en.wikipedia.org/wiki/Eutrophication

   Nitrates in drinking water can cause blue baby syndrome in infants and can react with chemicals used to treat water to create disinfection by-products in drinking water. [51] Getting direct contact with toxic algae through swimming or drinking can cause rashes, stomach or liver illness, and respiratory or neurological problems . [52]
