REMOVING NITRATES FROM WELL WATER USING ION EXCHANGE – A SIMPLE GUIDE
A nitrate removal filter using ion-exchange is a highly effective and proven technology used by many well water owners to filter nitrates and nitrites. There are a wide variety of nitrate removal systems (including reverse osmosis) on the market so it can be overwhelming when trying to find one that meets your exact requirements. If you are currently looking for a nitrate filter and want to know how you can benefit from using an ion exchange system, what to look for in a filter system and what questions you should be asking, then this guide is for you.
View our nitrate removal filters below
What is a ion exchange nitrate filter?
In the ion exchange process nitrate ions are exchanged by chloride (much like a standard water softener that exchanges hard water ions for chloride). When all chloride ions are exchanged with nitrate ions the resin is exhausted. Resin is regenerated with sodium chloride solution (standard water softener salt). 

Our ion exchange system are considered a point of entry (POE) nitrate filter, also known as a whole house nitrate filter is installed at the main-line of your plumbing where water enters your house or business. This type of filter removes nitrates in your kitchen and at other taps throughout your house should you want it; such as your bathroom, all sinks or utility room. 
​View our nitrate removal filters below
​Do nitrate filters also soften hard water? 
Hard water scale can greatly reduce the lifespan, effectiveness and removal capacity of the nitrate resins. Therefore, our Nitrate Eaters offer both hard water softening and nitrate removal all in one system. If you already have a water softener we offer our "Nitrate Only" Nitrate Eater which is installed after your existing water softener.  
​View our nitrate removal filters below
​How do I know if my well water needs an ion exchange nitrate filter?
High concentration of nitrate in water is a potential hazard for two reasons.
  1. The nitrate ions form complexes with the blood and in the long run cause oxygen depletion affecting human & livestock life.
  2. The flow of nitrate bearing water through iron pipes can cause depletion of oxygen leading to corrosion.
In view of these difficulties use of an Ion Exchange resin is the preferred process for nitrate removal.
​
Basically, if you need water to be of a higher quality than your private well water supply, then a ion exchange nitrate filter system might work for you.  As there are many different well water filters to choose from, it is worth having your water analyzed.  Before you purchase any filter for your well we recommend that you obtain a water quality test report for your well water supply, which will help identify any issues that are essential to deal with and those you may wish to improve. If you have a water report please email us at Support@RainDanceH2OStore.com Attn: Whole House Nitrate Filter - Or contact us about our FREE well water testing.

The RainDance Nitrate Eater Nitrate Filters Are Designed For Whole House Filtration, Commercial Business, Agriculture & Livestock Use
What Are Nitrates?:  Nitrate (NO3) is an inorganic chemical composed of nitrogen and oxygen. High Nitrate contamination of drinking water usually results from runoff of agricultural fertilizers or from human or animal wastes, such as livestock feedlots or faulty septic systems.
How Much Nitrate Is Allowed In Drinking Water? The maximum contaminant level (MCL) for nitrate in drinking water is 10 milligrams per liter (mg/L or ppm)). This is the maximum allowable level of nitrate that may be present in drinking water without a high risk of causing health problems. 
How Much Nitrates Will The RainDance Nitrate Eater Filter? The Nitrate Eater can treat up to 150ppm of well water nitrates - you can expect your nitrate level after the Nitrate Eater to be below the maximum contaminant level (MCL) and in most cases non-detectable levels.  
How Do I Know If There Is Nitrate In My Well Water? Since nitrate is colorless, tasteless, and odorless, you cannot tell if you have nitrate in your well water unless you test for it. Nitrate is more often found more in groundwater than in surface water. Nitrate is commonly found in shallow wells that are located in agricultural areas. Nitrate levels in ground water may change over time, especially after a heavy rainfall. Nitrate concentrations above guideline levels have been found in well water samples throughout US., especially near heavily farmed areas. In some cases, wells located near each other may have different levels of nitrate, so you cannot rely on test results from a neighbor’s well. High Nitrates can be found in Arizona, California, Delaware, Illinois, Iowa, Kansas, Maryland, Nevada, Nebraska, Oklahoma, Oregon, Pennsylvania, Texas, Washington and Wisconsin.
​Nitrate Eater Features 
  • The EPA has approved ion exchange and reverse osmosis treatment methods for removing nitrates/nitrites. The maximum contaminant level (MCL) is 10 parts per million (ppm) nitrate as nitrogen (NO3 as N). A laboratory may also choose to express nitrate as nitrate (NO3 as NO3) in the water analysis, and in this case, the EPA MCL is 44.2 ppm (10 ppm as N is equivalent to 44.2 ppm as NO3).
  • Selective Nitrate resin is NSF certification under NSF Standard 61 for potable water municipal installations as a process media.
  • Unlike most nitrate filters, the Nitrate Eater is designed to soften your hard water as well as remove high nitrates.​ Why both?
  • Removes up to 150 mg/L Nitrate & 40 grains (684 mg/L) Hard Water!
  • Nitrate levels are reduced well below the EPA standard, and in most cases, non-detectable!​​
Nitrate Eater ​Advantages
  • Prevents Buildup on Dishes, Dishwasher, Washing Machine & Clothes!
  • Prevents Hard Water Scale!
  • Higher Quality Water! Crystal Clear, Soft, & Nitrate Free!
  • Connects to the Incoming Main Supply Line!

  • Keeps Glassware & Silverware Sparkling!
  • Household Cleaning & Maintenance is Reduced!
  • Reduces Existing Scale Buildup!
  • A Cost-Effective Alternative to Whole House Reverse Osmosis!
The Nitrate Eater is a self-backwashing system that automatically removes the trapped contaminants within the filter bed and washes them down the drain. This is accomplished with a digital electronic control valve that is mounted on top of the Nitrate Eater. This valve is controlled by an electronic meter that calculates the amount of water being used. Once the meter reaches x amount of gallons, it then initiates the backwash cycle that cleans the bed of filtration media and resets it for the next period of filtration. Easy maintenance - periodically add sodium pellets or sodium-free potassium pellets to brine tank needed to regenerate the media.
Are you concerned about Nitrates in your water well?
Nitrate levels in many well waters are often high. The legal limit in the US is 10 mg/l as nitrate. 
Over 60% of nitrate enters water from agricultural land. High concentrations of nitrate in water can cause
methaemoglobinaemia in very young children (blue baby syndrome).

The facts on Nitrates are important to rural well water owners all across the US. You don't have to give up on your well water, just treat it!
