Reverse osmosis, electrodialysis and ion exchange are the processes that can be used to remove nitrates. Neither reverse osmosis (see separation by membranes) nor electro dialysis (see dialysis membranes) are NO 3- ion-specific and, therefore, are only used when desalination has to be carried out at the same time (brackish water).

How does nitrate removal work?
Nitrate removal by ion exchange works on the same principle. Instead of sodium, these water filtration systems use chloride ions. When the contaminated water passes through the tank or cartridge, the resin beads will collect the nitrate ions and displace the harmless chloride ions into the water in their place.
Why do plants use nitrates?
Fertilizers for lawns, gardens, flowers, and crops all use nitrates to provide the plants with this natural energy to help the plants flourish and remain healthy. When these fertilizers are carried by floods or rainfall into streams and lakes, nitrate levels in the groundwater will escalate.
Where are nitrates found?
Nitrates are compounds that occur naturally within the earth but are found in elevated levels in agricultural communities and rural towns.
How does reverse osmosis work?
Reverse osmosis removes contaminants by forcing pressurized water through a semi-permeable membrane covered in microscopic pores. These pores act like a sieve, separating the pure hydrogen and oxygen from the water’s contaminants. The membrane has such a fine micron rating that it can rid the water of ions, like nitrates. The clean, treated water passes through the membrane and collects in a storage tank. The remaining contaminants are rejected by the membrane and flushed down the drain in a brine solution. Reverse osmosis is one of the most powerful methods of residential water filtration and is able to reduce over 98% of waterborne contaminants. Generally speaking, reverse osmosis can specifically remove anywhere from 83-92% of nitrates.
How long does it take to distill water?
Most household water distillers will take between 4-6 hours to distill a single gallon of water. If you have potentially dangerous levels of nitrate present in your drinking water, this is a very long wait for potable water. Furthermore, water distillers do take quite of bit of energy to purify water.
How do nitrates enter water?
Nitrates enter the water supply through agricultural run-off, industrial waste, the use of fertilizers and herbicides, and from leaking septic tanks and burst sewage systems. Nitrates are one of the most common contaminants well owners are faced with eliminating from their water supply.
What is the purpose of nitrogen in fertilizer?
Fertilizers for lawns, gardens, flowers, and crops all use nitrates to provide the plants with this natural energy to help the plants flourish and remain healthy.
Can nitrates be found in drinking water?
The potential for nitrate contamination of drinking water also depends on the depth and construction of wells. Many factors can make it difficult to identify the source of nitrates for an individual well. Because nitrates move with the flow of groundwater, the source may be far from the well.
How does nitrate become toxic?
Nitrate becomes toxic primarily when bacteria in our digestive system convert it to nitrite. The nitrite oxidizes iron in the hemoglobin of our red cells to form methemoglobin. Hemoglobin transports oxygen through the body. However, methemoglobin cannot bind oxygen and, therefore, cannot supply oxygen to the body.
What is the composition of the atmosphere?
The earth’s atmosphere consists of 70 percent nitrogen. When nitrogen interacts with another element in the environment, it changes form and becomes a compound. Two kinds of nitrogen compounds found in nature are nitrates (NO3) and nitrites (NO2).

Two kinds of nitrogen compounds found in nature are nitrates (NO3) and nitrites (NO2) . Nitrates and nitrites are chemicals that are made up of nitrogen and oxygen and that combine with various organic (related to or derived from living organisms) and inorganic compounds.
What are nitrates made of?
Nitrates and nitrites are chemicals that are made up of nitrogen and oxygen and that combine with various organic (related to or derived from living organisms) and inorganic compounds. Once taken into the body, nitrates are converted into nitrites. Nitrates occur naturally in drinking water. However, if there are high levels ...
Can nitrates be harmful?

They’re a much more common problem in wells, especially in rural areas with high levels of agricultural activity and high use of fertilizers. Farming processes, such as the use of fertilizer and septic systems and rearing livestock, are two key causes of nitrate in drinking water.
Is nitrate bad for you?
Consumption of water that’s contaminated with nitrate may make humans more susceptible to public health risks, especially in babies, children, infants, and pregnant women. Concentrated, high levels of nitrate may affect the red blood cells in infants, preventing them from being able to adequately transport oxygen to the different parts of the body.
How are nitrates produced?
They’re produced when plants decompose, and can also be found in animal waste. Nitrates in water may be produced from agricultural processes. There are several ways that nitrates can get into groundwater: flooding, soil erosion, and, most commonly, rainwater and snow. If you have a shallow well, you’re more at risk of a small amount ...
Where do nitrates occur?
Nitrates are a type of inorganic compound that often occur naturally in the environment, including the soil, the atmosphere, and water. They may also occur synthetically as a result of human activity.
What is the main source of nitrates in water?
Rainwater is the biggest cause of nitrates and other organic and inorganic minerals in drinking water; it carries manure from farm livestock containing nitrates, and fertilizers from crops, into lakes and streams and down through the earth. Here, nitrates present in groundwater can enter wells through aquifers.
Is it safe to drink water with nitrates?
If your water contains less than this amount of nitrates, you’re fine to drink it, as it’s considered “safe”. 10 milligrams per liter may also be measured as 10 parts per million (PPM). 1 PPM is equal to 1 mg/L, so whichever reading you get can easily be converted into the other.

Can you boil water to reduce nitrates?
If you boil, freeze, or let water stand, the nitrate level will not reduce. In fact, if you boil water for over 10 minutes, it would concentrate nitrate in that water even more. Also, if water gets boiled in an aluminum pan, it may convert nitrate into nitrite which is twice as harmful.

How does reverse osmosis work?
The purified water then passes through and gathers in a storage tank. Reverse osmosis removes around 83% – 92% of nitrates from water. Water gets wasted in the reverse osmosis process.
How do nitrates get into water?
Nitrates often find their way into drinking water through the erosion of natural deposits in the ground and do not generally cause health problems. But human activities such as fertilizer and manure applications in farming are increasingly becoming the greatest source of elevated concentrations of nitrates in drinking water.
