NITRATE REMOVAL FROM GROUND WATER – A REVIEW
An ion exchange process was tested for the removal of nitrate from ground water containing 16-23 mg NO 3-/L at flow rates of up to 31.5 L/m2. s27. Treatment of sulfate water with resins is difficult as the nitrate removal capacity of the resin is reduced by the sulfate ions. It was observed that sulfate selectivity was reduced by
In McCook, Neb., a 15-year-old nitrate contamination problem that increased in scope over the years to also include uranium and arsenic was solved through the installation of a multi-contaminant-removal ion exchange treatment plant for the city’s drinking water.

Nitrate in drinking water is a global issue, and it is a regulated contaminant by the U.S. Environmental Protection Agency as well as the World Health Organization. Ion exchange technology is an effective solution to treat water systems and help municipalities, manufacturers and other industry professionals comply with regulations.
Low-Cost Solution to Treating Nitrates in Drinking Water | WQP
Ion exchange is a proven technology commonly used in residential water softeners to treat hard water as well as in industrial processes to remove metals and other contaminants from wastewater. At Blissfield, anions (negatively charged nitrate and sulfate ions) are selectively removed in the treatment process.
Pure Aqua, Inc. designs and manufactures both standard and specially engineered ion exchange water filter equipment for an array of applications including deionization (separate and mixed bed), dealkalizers, nitrate removal from water (NO3), and condensate polishers.
Ion Exchange Treatment Systems | AdEdge Water Technologies
Ion Exchange (IX) is a method of removing undesirable metallic salt ions from water by exchanging them with other ions attached to a media or resin. This chemical process occurs because ions have differing affinities for the resin and these ions will replace ions with less attraction as they flow over the media.
Source water protection is an important step in the implementation of a multi-barrier approach that ensures delivery of safe drinking water cost effectively. However, implementing source water protection strategies can be a challenging task due to technical and administrative issues. Currently many decision support tools are available that mainly use complex mathematical formulations. These

- Why is polyacrylamide better than agarose?
- The pores formed in polyacrylamide are smaller than those of agarose, used for agarose gel electrophoresis. This makes it more suitable for the separation of proteins over large polynucleotide DNA or RNA fragments and allows the separation of relatively small proteins.
- Why should you choose wholesale polyacrylamide & chemical products supplies?
- Wholesale polyacrylamide and chemical products supplies from our company are high-quality and affordable. You will enjoy our quick responses from our sales team whether it is wholesale, pre-sales, post-sales or something in between; We are at your disposal all the time.
