Nitrate Removal Using Ion Exchange Resin | Purolite | www

Water chemistry, system design and intended use for the final water are critical factors to consider when choosing resin for nitrate removal but nitrate selective Strong Base Anion (SBA) resin such as Purolite ® A520E is highly effective for retraining nitrate ions. Purolite's ion exchange resins for nitrate removal are particularly beneficial.

Nitrate Removal by Ion Exchange - For Water Treatment

Resin Treatment Choices. Standard anion resins. The two types of standard resins commonly used for nitrate removal today are Type 1 and Type 2 strongly basic anion exchange resins. The Type 1 resin derives its ion exchange capabilities from the trimethylamine group. The Type 2 resin derives its functionality from the dimethylethanolamine group.

Ion Exchange | Radionuclides in Drinking Water | U.S. EPA

There are two types of ion exchange—anion exchange and cation exchange. Anion exchange resins generally exchange chloride for anionic contaminants, like uranium. Cation exchange resins generally exchange sodium or potassium for cationic contaminants, such as radium. Mixed bed resins with cation and anion exchange media in two layers are available for systems that need to remove both radium and uranium. Ion exchange is also effective for the removal of beta particles and photon emitters.

Drinking Water Treatment – Anion Exchange Units – Drinking

If removing nitrate, the removal capacity will depend on both the nitrate and the sulfate concentration in the water, as anion exchange resins preferentially adsorb sulfate. The sulfate will bump nitrate from the resin and into the treated water when all the exchange sites are filled. The size of the unit needed and the time between regeneration also depend on daily water use and flow rate. Maintenance of anion exchange units

The anion resins used in nitrate removal applications are regenerated with ten percent brine at a dosage of about ten pounds per cubic foot. The service flow rate can be between two and four gallons per minute per cubic foot. A minimum resin bed depth of 30 inches is recommended, 36 inches is preferred.

Drinking Water Treatment – Cation Exchange Units

Anion exchange devices remove anions (negatively charged ions such as arsenic and nitrate) and replace them with chloride. Mixed media ion exchange units remove both cations and anions. A typical mix would be 60 percent cation exchange material and 40 percent anion exchange material. The units usually must be regenerated at a central processing

Ion Exchange | Arsenic in Drinking Water | U.S. EPA

In drinking water treatment, this technology is commonly used for softening and nitrate removal. Arsenic removal is accomplished by continuously passing water under pressure through one or more columns packed with strong-base anion (SBA) exchange resin. These resins are insensitive to pH in the range 6.5 to 9.0.

Nitrate-selective vs. standard resins. Ion exchange resins have long been used for nitrate removal. Generally speaking, there are two kinds from which to choose: "nitrate-selective" and "standard." The major difference between them is the relative affinity of multivalent ions like sulfate and arsenate.
