Mercury remediation system demonstrated to reduce contamination in power plant wastewater
Low-cost, reliable remediation system proven to address a range of trace metal contaminants, including ionic mercury.
The operation principle of the SafeGuard™ H2O system is based on a proprietary approach that generates an electrolytic stannous reagent on demand. As a result, the system is free from the drawbacks of using a traditional stannous chloride reagent. In fact, freshly generated stannous ion using tin metal precursor provides very accurate reagent dosing. This reagent poses no environmental and health risks.
AMS conducted a bench test study on its SafeGuard™ H2O mercury treatment system with both settled (clarified) Flue Gas Desulphurization (FGD) wastewater and unfiltered wastewater samples and achieved up to 99.9% mercury removal for settled FGD and up to 98% removal for unfiltered FGD wastewater. No sample preparation, such as pH, ORP adjustments were required to achieve high mercury removal efficiency. In addition, the system can operate in batch or continuous flow mode and is scaleable to large and small treatment volumes.
AMS’s bench test study concluded that its SafeGuard™ H2O system can effectively remove dissolved ionic mercury from both unfiltered and settled FGD blowdown wastewater, making it a cost-effective alternative to highly challenging and expensive existing mercury removal processes.
