 This Nitrate Filter System is built utilizing ProSelect™ Nitrate Resin as the primary functioning layer. Finally, there is a way to treat nitrate- contaminated well water, easily and safely. After programming with your current nitrate levels, this microprocessor-based system will monitor your actual water usage patterns and economically regenerate only as needed, to ensure nitrate-free water at all times for the entire home. This system also features a Cyclonic Distributor System™ to provide full bed contact, less channeling, and superior backwashing.
System Features: 
- Removes up to 50 PPM of nitrates per gallon of water
- Regenerates with ordinary chloride (salt)
- Even if the nitrate filter bed is completely full, nitrates will not release back into the water
- A fraction of the cost of digging a new well or linking up to a city water main
- 100% corrosion-free system
- Fully programmable, energy efficient controller uses less than $5.00 of electricity per year
- 10 year tank warranty, 5 year valve warranty
This system also features the Cyclonic Distributor System™ providing higher flow rates, less pressure loss, improved treatment capacity, product flexibility, and water conservation.

Operating Pressure: 20 to 125 psi (1.4 to 8.6 bar)
Operating Temperature: 36 to 120°F (2 to 48.9°C)
NOTE: Please specify nitrate and sulfate levels in order for factory to properly program capacity.
System capacity is rated for total nitrate capacity only. Allotment of up to 50% of total nitrate capacity may be consumed by other ions in the raw water. Before installing a nitrate system, we recommend a water analysis and consultation for proper equipment sizing and regeneration settings. MORE ON NITRATE REMOVAL
The science of nitrate removal is simple, but for obvious reasons, cannot be taken lightly. The two most often used technologies for nitrate reduction are Reverse Osmosis (RO) and Ion Exchange. Ion Exchange is a more recent technology. RO is much more costly per gallon of treated water, except for third faucet drinking water applications. RO is a more foolproof method with less maintenance responsibility to the homeowner, but impractical in whole house applications.
Up until recently, nitrate was an ion that, once pulled from the water with a resin bed, had a very loose hold on the resin bead. A competitive ion, such as sulfate, could come along and push an already held nitrate ion back into the water. Only recently has this problem been overcome.
ProSelect™ Nitrate Resin is one of the first of its kind that will not allow a competing ion to displace a captive nitrate ion back into the water supply. However, the selective advantage of the resin bead to the nitrate is still minimal. This means it almost acts as a first come, first served, competition with a slight preference going to the nitrate. Other ions in the raw water will not displace the nitrate back into the water stream, but nitrates will not always displace sulfates either. That is why in all nitrate removal applications, a water analysis should be done to establish the true amount of nitrates in the water. You also need to know if there are sulfates present, which will compete for room in the resin bed. Then system is then sized accordingly.
Fortunately, this is very easy to do, and only requires a little math. If, for example, you have 30 PPM of nitrate, and 10 PPM of sulfate, that means you have a total of 40 PPM fighting for room in the bed. 25% is sulfate, and 75% is nitrate. That means that in a 1 cubic foot nitrate system with a capacity of 67,000 PPM/10 lb. of salt regenerant, the bed will be completely exhausted after 16,750 PPM of sulfate and 50,250 PPM of nitrate. So your total nitrate capacity would be 50,250 PPM nitrate (75% of 67,000 PPM) or 1,675 gallons of water. (50,250 PPM of room divided by 30 PPM/gallon of water equals 1,675 gallons before the bed is full.)
(Total bed capacity) – (% of sulfate to nitrate) = (Total nitrate capacity)
Still, some dealers like to reduce that number to err on the safe side. They may leave a 20% buffer to allow for an excess of water use.
OTHER THINGS TO REMEMBER
- A nitrate system should always follow an iron filter or a water softener in any multi-tank treatment system.
- Iron will foul out a nitrate resin faster than a cation resin.
- Both a water softener, and a nitrate removal system use salt (sodium chloride) to regenerate, however, the nitrate resin is using the chloride side of the salt for regeneration, as opposed to a water softener which uses the sodium side.
- Potassium chloride can be used, but remember, potassium chloride on average has 20% less chloride per pound than salt. Control settings have to be adjusted accordingly.
