Permanganate oxidation remediation technology has two major advantages: low secondary pollution and rapid pollutant remediation, which can save on materials, monitoring, and maintenance costs during the remediation process. Additionally, permanganate oxidation remediation offers diverse agent delivery methods and high flexibility in treatment plans, which can be adjusted and optimized according to the site's actual needs. As a result, the permanganate oxidation remediation method is widely used.

Permanganate oxidation remediation technology is divided into in-situ permanganate oxidation technology (ISCO) and ex-situ permanganate oxidation technology (ESCO). In-situ permanganate oxidation involves injecting permanganate oxidants into the soil environment, where they react with pollutants to convert them into harmless substances.
