Cl₂/UV AOP treatment processes are highly complex and dependent on a number of water chemistry and treatment process parameters. With over three years of direct experience, MIOX is in a unique position to apply its expertise towards customer-specific optimization of Cl₂/UV AOP treatment processes with the goal of reducing costs and improving safety. The use of MIOX’s On-Site generation systems, which produces aqueous chlorine from non-hazardous sodium chloride brine, offers a safer and superior chemical introduction into AOP treatment trains compared to concentrated hydrogen peroxide or bulk hypochlorite.
Aerojet Rocketdyne, Inc. (Aerojet Rocketdyne) oversees a groundwater remediation program at their Rancho Cordova facility. Aerojet Rocketdyne was tasked with removing perchlorate, VolatileOrganic Compounds (VOCs), and N-nitrosodimethylamine (NDMA) associated with historic Aerojet Rocketdyne operations from the groundwater. As a result, Aerojet Rocketdyne designed, built and operates several Groundwater Extraction and Treatment (GET) facilities to achieve its long-term remediation goals, treating over 25 million gallons of groundwater per day. At several GET facilities, Aerojet Rocketdyne utilizes a treatment technique called Advanced Oxidation Processes (AOPs) to facilitate the removal of VOCs. AOP technology currently deployed at many Aerojet Rocketdyne GET sites generates highly reactive radical species by using UV to break apart hydrogen peroxide (H2O2). While AOP methods that employ H2O2 are effective at meeting remediation goals, H2O2 is a costly chemical that, without proper safety equipment and training, could present a hazard in the work place. MIOX’s Applications Research Group anticipated that hypochlorite could replace the H2O2 effectively, thereby lowering operational costs and possibly reducing hazards in the work place, key Aerojet Rocketdyne priorities as they improve ongoing remediation processes.
