Detailed Description:

20" Big Blue Anion Resin Filter for Tannin Reduction

Food-grade strong base anion resin helps reduce and remove tannins and nitrates from incoming water. If you're on well water and/or your supply has a brownish discoloration that can't be removed with sediment or an Iron/Manganese filter an anion filter could be the solution you're looking for.

WHAT IS TANNIN?

Tannins are large molecular-weight organic compounds commonly found in plants such as the bark, leaves, and fruits of certain trees, but can also be found to a lesser degree in animals. This can cause decaying organic compounds to be present in water. Tannins are astringent, bitter-tasting plant polyphenols that bind and precipitate proteins. The structure of the tannin varies from location to location, depending on the vegetation in the area.

In water treatment, tannins can cause discoloration, a bad bitter taste, and reduce the effectiveness of R.O. ( reverse osmosis) systems and thus affecting your water quality. For this reason, it is important to remove tannins from water used in R.O. systems pH 6 and can be treated with anion exchange resins.

WHAT IS NITRATE?

Nitrates are chemical salts found naturally in mineral deposits that are commonly used in fertilizers. Long-term nitrate exposure can result in kidney damage and certain types of cancer. Nitrate exposure in infants is especially dangerous and can lead to serious health conditions such as methemoglobinemia. Fertilizers are generally broken down by plants as they use the material to grow, but the main source of nitrates in water is agricultural run-off that enters the local water table.

HOW DO YOU KNOW IF I HAVE NITRATE IN MY WATER?

1. Test kits: You may buy these kits online or at home improvement stores. A little amount of water is often added to a chemical solution, which will change color if nitrates are present. The solution's hue can then be compared to a chart to yield the nitrate content.

2. You can also submit your water for testing in a laboratory. Testing services are provided for free or at a low cost by some municipal health authorities or water utilities. An alternative is to submit a water sample to a private lab for examination.

note:we do not take testing

3. Nitrates can occasionally be found through visual inspection. Nitrate contamination may be present if your water is reddish or brownish in color or tastes metallic.

Whichever approach you choose, it's crucial to frequently test your water to make sure it's safe to drink. Serious health effects from nitrate exposure can occur, especially in young children and pregnant women. If you are worried about the quality of your water, you should act quickly to resolve the situation.

TANNIN REMOVAL

Experience the benefits of our specially-designed water treatment medium that uses anionic resins to remove tannins and other negatively charged ions from your water, providing you with a pure and refreshing drink.

Tannin molecules tend to form anions in water above pH 6 and can be treated with anion exchange resins. Tannins below pH 5 are better treated with activated charcoal.

Using a softener beforehand removes hardness and metals ( like iron ) that might otherwise foul the anion resin, reducing its ability to remove tannins.

Tannin removal is dependent on the vegetation in a given area and thus the amount and type of resin necessary can vary; If your well water has a slight yellow or brown tint, the addition of one pound per inch in diameter of your media tank will normally make the water clear. If your water is darker, like Ice Tea, you may need as much as two pounds per inch in diameter of your media tank. There are various methods and each one can vary in result, this is why monitoring your water's results is an important factor in determining the desired results you want to achieve.

The "color" or "tannins" are tested by running the water at the well for a minute or two, then taking a sample in a cup or bucket and observing the color IMMEDIATELY before the iron reacts with the air ( oxygen ).

You only need the extra Tannin removal resin in with your regular softening resins if you have color when the water is first drawn.


CLEANING METHOD

When a tannin color passes through a working unit, an attempt should be made to clean the resin. Soda ash (Na2CO3) can be added to the brine to help clean the anion resin. 0.5 to 1 pound of soda ash is typically added to the brine well. A second regeneration should be performed after the resin has been treated with soda ash to completely convert the resin to the chloride form.

If the soda ash method fails to clean the resin, a chlorine treatment can be used as a last resort. This method isn’t recommended because it’s extremely harsh on the resin. Fill the brine well with four to eight ounces of household bleach and set the system to regenerate. Shut down the system for one to two hours if a chlorine odor is detected in the drain line. After the system has soaked, complete the rest of the regeneration cycle. To remove any remaining chlorine, a second regeneration should be performed. Ion exchange resin is not chlorine resistant. If this treatment is unsuccessful, the replacement must be considered.

Before attempting any cleaning procedure, regenerate the bed with salt if the unit contains both cation and anion. Due to high pH or oxidation, any metals, such as iron, will precipitate on the cation resin.


SERVICE CYCLE

Tannin removal with anion exchange resins involves both ion exchange and an absorption process. There is a slight negative charge in tannins. As a result, they are exchanged for chloride in the resin. To regenerate the anion resin, salt (NaCl) is used. In general, the resin will be brined at a rate of about 10 pounds of salt per cubic foot. It is critical to regenerate the resin on a regular basis. Every two to three days, the system should be regenerated. The anion resin is less dense than cation resin.

Backwashing an anion resin should not be done at the same flow rate as a cation-softening resin. Backwashing the anion should be done at a flow rate of about two gpm/sf. Organic fouling can be reduced by performing frequent regenerations.

Tannin resin is a residual by-product of anion resin. The amine from the resin is usually in very low concentrations, but the odor threshold is around 40 parts per billion. When ammonia and chlorine are mixed, they create an environment that breaks down resin, and the ammonia causes the pH to rise. If the TDS levels in the influent water exceed 800 ppm, a salty taste may be detected. To reduce the TDS and salty taste, RO will be required.


OTHER METHODS OF REMOVING TANNINS

Chlorine and other oxidising agents are effective at breaking down organic compounds such as tannins. A simple jar test will reveal the concentration and time needed to oxidise tannins. Following the retention tank, an activated carbon unit will remove the chlorine and may adsorb other organic compounds in the water. Some types of activated carbon may be able to reduce tannins to acceptable levels on their own. For the appropriate type of carbon, contact your carbon manufacturer. It should be noted that the reaction between chlorine and tannins may produce carcinogenic trihalomethanes (THMs).

Another effective tannin removal method is reverse osmosis. The term "electronic commerce" refers to the sale of electronic goods. Tannins, on the other hand, have a tendency to foul the system's membrane. Installing a whole-house RO system to treat all of the water is also very expensive. Check with your local water doctor for more information.


SAFETY

Acid and alkali solutions used for regeneration are corrosive and should be handled with caution and safety to avoid contact with your eyes and skin. We advise wearing goggles and gloves during the entirety of the process. If oxidizing agents are used, the necessary safety precautions must be taken to avoid accidents and resin damage.


STORAGE

Ion exchange resins must be kept moist and stored in a cool, shaded place. The recommended temperature range is between 20 and 40 degrees Celsius. It is important to regularly check the condition of the resin and add clean demineralized water and keep it in completely moist condition water if needed. The resin should never be allowed to dry out. Always keep the resin drum in the shade.


MAIN PURPOSE

For water purification, wastewater treatment, biological products, and the hydrometallurgy of tungsten, molybdenum extraction.


OTHER USES

Water softening, desalination of water preparation, preparation of pure water, and high water. Amino acid extraction and purification, extraction, and purification of antibiotics. Extraction and removal of heavy metal ions, separation and purification of rare earth elements, and organic synthesis reactions, as hydrolysis of the acid esterification catalyst.
