Activated carbon filtration is known for its efficiency in reducing hexavalent chromium levels.

Reverse osmosis

Reverse osmosis is another effective treatment method for removing hexavalent chromium. It involves forcing water through a semipermeable membrane, effectively trapping and removing chromium ions and other contaminants. Reverse osmosis systems can be installed at the point of use or as a whole-house system, depending on your specific needs.

Ion exchange

Ion exchange is a water treatment process that involves the exchange of ions between a resin material and the water. This method can effectively remove hexavalent chromium by replacing it with less harmful ions. Ion exchange systems are typically designed as whole-house systems and require regular maintenance to ensure optimal performance.


Electrodialysis is a water treatment method that uses an electric current to selectively remove ions from water. This process can be effective in reducing hexavalent chromium levels in well water. Electrodialysis systems are typically more complex and expensive to install compared to other treatment methods, making them suitable for larger-scale applications.


Distillation is a purification method that involves boiling water and collecting the resulting steam, which is then condensed into clean water. This process effectively removes contaminants, including hexavalent chromium. However, distillation can be energy-intensive and may not be the most practical option for every situation.

UV oxidation

UV oxidation is a treatment method that utilizes ultraviolet light to break down and neutralize harmful compounds, including hexavalent chromium. This process disrupts the chemical bonds and renders the chromium ions less toxic. UV oxidation systems are often used in conjunction with other treatment methods to provide comprehensive water purification.

Combination of treatment methods

In some cases, a combination of different treatment methods may be necessary to effectively address elevated levels of hexavalent chromium. This could involve a multi-stage treatment process, utilizing various technologies in sequence to ensure thorough and reliable removal of the contaminant. Water treatment professionals can guide you in determining the most suitable combination for your specific needs.
