How to Remove Nitrates from Water

How to Remove Nitrates from Water

Nitrates are the most common contaminants in groundwater most of the Well owners faced. It mainly originates from excessive fertilizer use and treatment of land discharge from wastewater. Excessive amounts of nitrates cause health hazards in humans and livestock.

However, it makes limited to direct use of land water in various countries of the world to avoid the effects of nitrates. In this article of How to remove nitrates from the water, you will get to know the conventional and non-conventional process to get rid of nitrates.

How Nitrates does come in Water?

Nitrates in actual occur in the surface of groundwater at a moderate level; that does not cause any health hazard. However, the improper construction of well, excessive use of chemicals and detergents, and animal and human waste disposal could cause an increase in nitrates level in groundwater.

Well, various sources cause the mixing of nitrates in well water including the septic system, food processing waste, and industrial disposal. Mostly, flooding contaminates the shallow well badly. The wells bored or dugs get submerged for a long period after flooding. Anyways, we are blessed to have a solution to how to remove nitrates from water efficiently.

How do you test of Nitrates in Well water?

There are various ways to do attest of you well water for nitrates level. The best way is to take a sample and submit it to a certified laboratory for tests. There they perform 75 different evaluated tests for nitrates give you a detailed well water assessment and quality.

The details you get will be about taste, odor, and color of the water. So, testing is the best thing you can do to determine the water condition at your home. Mostly the lab sample is measured in ppm (parts per million) that represents the completely well water.

Now, if you already have tasted your water from the laboratory as per EPA standard and installed a filter, you can check your water regularly by strip testing. These testing strips are color-changing, they can easily get you idea either the nitrates are present or not in water.

Harmful effects of nitrates in water

Although a normal amount of nitrates are present in water, its excessive levels cause various harmful effects in humans. The intake of elevated amounts of nitrates regularly causes a decrease in RBC’s cause a lack of oxygen transport in the whole body.

In infants, the intake of high-level nitrates in water could cause methemoglobin (the blue baby) syndrome. This could cause a drastic effect on baby health. So, you must take extra care about the issue of nitrates. In this article, you will get detailed guidance to remove nitrates from water.

Methods to Remove Nitrates from Well water

Nitrates elements are difficult contaminates to remove from water. Still, there are various ways to remove nitrates from water. Commonly used methods are ion exchange resins, distillation, sediment, reverse osmosis and carbon filters.

The conventional boiling and softening method are not able to remove nitrates. To get rid of such contaminates you need to install a Resin anion tank at the main point of water supply.

In case of clean water, only for drinking and cooking purposes, you need to install sink tank water filters in the kitchen. Water distillers are also beneficial to remove nitrates for the whole house water use.

1. Water filter distiller

Water distillation is one of the best processes to remove nitrates from water efficiently. It is capable to remove all the contaminates, salt including water-borne microbes. This procedure includes the hydrological cycle and the evaporation of water from Sea Ocean and groundwater. In evaporation water normally changes into droplets on heating all the liquid then turns into vapor.

Water distiller filters have minimized the long evaporation process. In this the water placed into a chamber, heat is provided until the whole water changes into steam. This steam collected into a cooling coil. Water turns into liquid here and then collected into the pitcher or jug of the filter. In the procedure of turning water into steam and liquid all, he contaminates left behind in the bottom of the chamber. The VOC’s contaminates turns in to the gas, no nitrates particle survive in this procedure.

Most of the powerful household distiller takes 4-6 hours to produce a gallon of water. If the nitrates are present at a high level, portable water filters take more time. Water distillers use a huge amount of electricity and can produce 2-3 gallons in a day. Despite its high energy consumption, it’s a surefire way to provide high-quality clean water to the whole family.

2. Reverse osmosis

The reverse osmosis method is efficient to remove 80- 95% of nitrates from water. In this method, pressurized water is passing by a molecular semi-permeable membrane. A porous sieve works to separate the oxygen and hydrogen from the contaminates. The completely treated water collected into a water tank. The remaining pollutants and nitrates leave behind the membrane.

This is the most popular method to provide purified water for cooking, drinking, and other household use. The reverse osmosis process of water filtration seems quite hectic as it has many pre-filter stages. Sometimes, the filter pressure sucks the whole house water to increase the water pressure inline. Reverse osmosis is the best choice if you only want to remove nitrates for your whole family.

In the older reverse osmosis device, a large amount of water wasted. However, with the improvement in technology now the efficiency of RO has quite improved. If you have good water pressure in your home then reverse osmosis working will be more efficient. If you are dealing with low water pressure, it is recommended to add a booster pump with RO.

3. Resin ion exchange

The ion exchange process is the most effective method in terms to eliminate the nitrates from water. Commonly ion exchange method found in traditional water softeners. Now, this method helps to remove contaminants other than hard water. A brine solution is a use in the water softener to regenerate resin beads with the sodium ion.

In the ion-exchange method, nitrates are removed in the same way as in the case of sodium ion. In the case of nitrates, chloride ions are used. When the contaminated water passed through it the nitrates ion get exchanged with harmless chloride ion. The chloride and nitrates both carry negative charge this method also called anion exchange method.

Nitrate selective ion exchange system installed in the main supply. It is efficient enough to provide high-quality nitrate-free water to the whole house. Before installation, you must get a sample check of your water. In the case of the presence of sulfate ion, the media will decrease the effective reduction of nitrates.

The placement of the system is another important factor. Do not place the system near the drain line. The system need periodically flush of sodium chloride in term to regenerate resin and cleaning of brine solution. The residue brine solution carries the nitrates collected by ion exchange.

This method is highly efficient to remove a huge amount of nitrates. For a healthy lifestyle and avoid the drastic health effect you must install this system fro your main water supply. We assure you this will help you to remove the nitrates for every droplet of water from your house.

Prevent nitrate from mixing in water:

There are various precautionary measures to prevent the mixing of nitrate in water.

Regular water check: You must take care of the water quality by proper checking. A good laboratory test should do annually.

Construction of Well away: Construction of well in shallow areas has more chance of high level of nitrates. You must have relocated you well if it is constructed in deep areas.

A wise selection of Construction: The well should be contributed away from fertilizer and pesticide manure. If the Well is specifically constructed for agriculture the save the crop, it’s better to use such chemicals away from Well.


In the above article, how to remove nitrates from water; we have mentioned detailed information to remove nitrates. Just keep in mind that nitrates cannot remove on boiling. You need to treat the contaminated water with proper procedures and methods.

The above mention methods include ion exchange, water distillers and reverse osmosis are highly efficient to remove nitrate from water. As you know how must harmful the nitrates are for our health. To get rid of this you must have to take necessary measures by installing one such procedure.

Well, the above detailed is well researched and reviewed deeply to provide you the authentic information.

We tried our best to provide the widely used method to get rid of nitrate. We hope you will find the best one for your house. These methods can also be installed for household use. Enjoy the clean high-quality water. Happy Drinking!
