Ion Exchange Resin For Nitrate Removal

Lanlang® TA465D is a high-quality macroporous anion exchange resin of type I, which contains a polystyrene matrix and a quaternary amine (triethylamine) function group. Its size distribution is standard Gaussian.

TA465D ion exchange resins for nitrate removal are particularly beneficial. Designed specifically for potable water treatment, TA465D is an efficient and practical solution for the removal of nitrate and nitrite. Ion exchange technology is an effective solution to treat water systems and help municipalities, manufacturers and other industry professionals comply with regulations.

Nitrates have no detectable color, taste or smell at the concentrations involved in drinking water supplies, and they do not cause discoloration of plumbing fixtures, so they remain undetectable to our senses. Nitrate removal processes must be either foolproof or include extensive monitoring of the treated water to detect breakthrough or determine the need for regeneration.

Nitrates in concentrations above 10 ppm expressed as N* (this can be expressed as 35.7 ppm as calcium carbonate or 44.3 ppm as nitrate) are considered unsafe. Nitrates have no detectable color, taste or smell at the concentrations involved in drinking water supplies, and they do not cause discoloration of plumbing fixtures, so they remain undetectable to our senses. Nitrates do not interfere in non-potable domestic uses such as laundering. Therefore, nitrate removal processes must be either foolproof or include extensive monitoring of the treated water to detect breakthrough or determine the need for regeneration.

Infants are particularly susceptible to nitrates because their digestive systems do not operate in the exact same manner as adults. Nitrates are converted by bacteria in the stomach of infants to toxic nitrites. At levels that would not cause harm to adults, nitrates can cause methemoglobinemia in infants, a condition also known as "blue baby" syndrome.

Nitrates present in a water supply can be a symptom of other contaminants in that source of water. Have a full public health analysis performed on waters being considered for treatment. Disinfection may be necessary to counter other health concerns.

There are both natural and man-made sources of nitrates in groundwater. The main source of nitrate contamination appears to be from agricultural operations, farm runoff and fertilizer usage. There also is some nitrate formed in the atmosphere by oxidation of nitrogen oxides that are emitted from power plants and internal combustion engines. One other man-made source is industrial corrosion inhibitors that have leaked into the ecosystem.

Naturally occurring nitrate can result from a combination of nitrogen and oxygen through electrical discharges (lightning). Also, nitrate is formed by Nitrobacter bacteria by oxidation of nitrites.
