Frequently Asked Questions:

Q. What is the Difference Between the Point of Use, Fleck 9100, 7500, and 5900-BT Nitrate filter systems?

A. The Point of Use nitrate filter is for a single faucet.  The 7500 model uses a rugged ceramic disc for an extremely long life.  The 5900-BT series can be tracked and controlled on your smart phone with the free Bluetooth app.


Q. What is nitrate?

Nitrate is a naturally occurring chemical compound that is formed in the soil when nitrogen and oxygen combine. Small amounts of nitrate are normal but large amounts can pollute groundwater and cause severe consequences to life.

Sources of nitrate in the soil are chemical fertilizers, septic system discharge and livestock waste. A portion of chemical fertilizer will convert to nitrate in the soil. Ammonia is present in the waste of both humans and animals. It enters the soil from inadequate or poorly managed septic systems. Plants can only absorb so much nitrate from the soil and the excess is then carried down through the soil into the groundwater by the action of rain, snowmelt and irrigation.

Q. How is nitrate removed from my well water?

 

A. Nitrate is removed by either reverse osmosis or ion-exchange resin (the type of system on this page). In an anion exchange system, chlorides are exchanged for the nitrate, and the high nitrate waste is flushed into a holding tank or drain field. Similar to a water softener, salt is added to a salt tank, and the nitrate resin is regenerated automatically with salt water.
