There are currently two major technologies in use for perchlorate removal. Ion Exchange Technology uses a resin to absorb perchlorate and remove it from water, affording the opportunity for safe and appropriate disposal of perchlorate. Biological treatment is a process that uses microorganisms to break down perchlorate into other components. In this process, water can be treated in a tank or in the ground. The primary resulting component is chloride, which is part of common table salt. Other technologies are currently under development.
