What is the target pH range for chrome removal treatment?

The target pH range for chrome removal treatment is typically around 7.5 to 8.5. This range is essential because chromium, particularly in the hexavalent form, can be effectively reduced to its trivalent form under these alkaline conditions. The trivalent chromium is less toxic and more easily precipitated and removed from water. Operating within this pH range helps maintain optimal conditions for the chemical reactions necessary for chrome reduction, ensuring better removal efficiency and compliance with environmental regulations.

In contrast, lower pH levels may not facilitate the same effectiveness in terms of conversion and removal. Therefore, treatments designed for chrome remediation target slightly alkaline conditions to maximize chromium reduction and achieve desired treatment outcomes.
