Bluetooth Nitrate Extraction System

The structural pressure tank is a fiberglass-reinforced composite vessel with a durable plastic liner.

No special salt is required. Use standard water-softener salt, preferably high-purity evaporated salt pellets or solar salt crystals. Avoid rock salt because its higher impurity content can create sludge in the brine tank.

Thanks for reaching out — great question, and this one trips up a lot of folks because the Nitrate system looks like a softener at first glance.

Here's the quick breakdown: the system is sold as a complete unit with two tanks that work together — a tall resin tank (9" x 48") and a shorter brine (salt) tank. Even though it resembles a softener, the tall tank is filled with a special nitrate-selective resin, not softening resin, and the brine tank's only job is to hold the salt used to periodically regenerate that nitrate resin. Both tanks are required for the system to function, so they're not sold separately.

The good news is that it's designed to run alongside your existing water softener, not replace it — so your current softener stays right where it is and continues handling hardness. The Nitrate simply gets plumbed in as its own dedicated stage for nitrate removal.

And to your cartridge question — there's no cartridge to swap out. The nitrate resin inside the tank typically lasts many years, and routine maintenance is just keeping the brine tank filled with salt and occasionally using ResKleen resin cleaner (a free bottle is included with your purchase).

If you'd like help with flow rate sizing (7 GPM or 15 GPM) or the ideal plumbing order alongside your softener, reach out any time.

There can be a small normal pressure drop, as with any water treatment system, but it should not significantly reduce pressure when the correct size is selected for the home. This model is available in 7 GPM and 15 GPM sizes, so proper sizing is the key.

No, mineralization is not typically needed after this system. This unit is designed to remove nitrates from the water using specialty resin, but it does not demineralize the water the way a reverse osmosis system does. In most applications, no additional mineralization step is required. If you have other water quality concerns or want to address taste and drinking water preferences, our water specialists can help recommend any additional treatment if needed.

This system does not add sodium chloride to the water supply. This system is specifically designed to target and remove nitrates from water using a special type of resin that selectively exchanges nitrates with chloride ions. This process doesn't involve adding sodium (salt) to the water, unlike traditional water softeners that exchange calcium and magnesium for sodium.

Instead, this nitrate removal system uses a chloride form of anion exchange resin, which effectively reduces nitrate levels without altering the water's sodium content. This makes it a great option if you're looking to reduce nitrates while keeping the water sodium-free, particularly important for those on low-sodium diets or in areas where sodium addition to water is a concern.
