Nitrate as a Water Contaminant
Nitrates are classified as inorganic compounds that are usually present in surface water as well as in groundwaters depending on the location. Nitrates can originate from both the sources, the natural as well as the man-made. Nitrate is especially formed by fertilizer residues and the decomposition of waste that enters the water supplies directly or indirectly through the soil. Nitrate removal from drinking water can be fulfilled via anion exchange method, using WETS conventional ion exchange systems. Sometimes you can also use the nanofiltration (NF) method for Nitrate removal from water, as it employs a low-pressure spiral membrane, to soften the water and make it clean as desired.
Nitrate removal from water can be attained via either the Physical-Chemical method or the Biological method.
You can use Electrodialysis, Reverse osmosis, and Ion exchange methods for the Nitrate water treatment processes that can easily separate nitrate from the contaminated water and make it clean for drinking or cooking purposes.
Neither Reverse osmosis nor Electrodialysis are considered NO3-Ion-specific, hence, they can only be used when you want to desalinate the water at the same time of the cleaning process.
Nitrate removal from water can be done by using Ion exchange method and the resins used for producing clean drinking water are also approved in several countries.
Nitrate Removal from Drinking Water
Nitrate removal from drinking water can successfully be done using the treatment methods such as Distillation, Ion exchange, and Reverse osmosis. You can contact any health department in your area to know the recommended methods of treatment.
It’s a myth that boiling or heating the water will remove the nitrate content from it, No it won’t, it doesn’t work like that. Because when you heat or boil the water, some of it will evaporate but not the nitrate compounds. They will stay inside the water and it may increase the nitrate concentration levels in water. There are many mechanical filters or chemical disinfectants available in the market such as chlorination, but it DOES NOT remove the nitrate content from the water.
