and anion resins, used to remove anions like nitrate, arsenate, arsenite, or chromate from waste solution/water (Alexandratos2009; Calmon1986). Regeneration can be possible using sodium chloride. In case of cation resins, sodium ion displaces the cation from the exchange site; whereas in case ...

A. F. Miquel of Otto Oeko-Tech looks at potential water treatment technologies that are able to remove nitrates from drinking water and details the way in which the development of nitrate selective membranes has resulted in the adaptation of electrodialysis and the development of the Nitrem ...
Thus, once the surface water is contaminated by pesticides, it does not receive suitable treatment to remove them, and they will still be present in the water provided to the population. The Iowa DWTP performs the following steps: sorting, chemical pre-treatment, sedimentation, lime softening, ...
One of the goals of wastewater treatment is to remove nitrogen to prevent over-enrichment of receiving waters. Processes in the nitrogen cycle – specifically nitrification and denitrification – play a vital role in accomplishing this goal.

How to Remove Nitrates from Water What Are Nitrates? Nitrates (NO₃⁻) are naturally occurring compounds composed of nitrogen and oxygen. They are an integral part of the nitrogen cycle and are commonly found in soil, plants, and water. While nitrates are relatively stable, nitrites are mor...
