NuVision Engineering, Inc has access to a number of waste treatment and stabilization technologies. These have been developed and proven over a number of years for the safe treatment and stabilization of various wastes including;
- Ion exchange resins
- Nerve agents
- Explosives
- Propellants
- Plutonium contaminated cellulosic wastes (tissues, gloves, bottles, etc.)
- Acidic sludges
- Alkaline sludges
Combined with our Power FluidicsTM technology, these treatment options enable us to offer a comprehensive retrieval and treatment package to our customers.
One example is the ModulOxTM treatment process which has been developed by NuVision Engineering's sister company, WMT, during the past 15 years in response to concerns over the disposal of radioactive wastes containing certain types of organic materials such as cellulosics, ion exchange resins and wastes containing organic chelating agents.The technology has proceeded from bench top units through to mobile pilot plant and has been used to treat a wide range of organic waste streams including PWR type ion exchange resins, PWR circuit decontamination waste and active sludges.
The benefits of the ModulOxTM process are:
- Low temperature process
- Low atmospheric pressure process
- Simple single stage process design
- Process output can be readily tailored to further conditioning, storage and disposal requirements
- Volume reduction of wastes and associated economic benefits
- Removal of organic components to enable compliance with acceptance criteria for disposal
- Treatment of a wide range of organic wastes
Since many radioactive waste-producing sites do not generate sufficient volumes to justify a fixed facility and also because of the costs associated with decontaminating such a facility, the ModulOxTM system has been designed to be mobile. Such a system has been used in the UK to treat more than 400 liters of ion exchange resin and in Belgium to treat 3000 liters of aqueous organic liquid effluents. In both cases the treated products were compatible with the existing water treatment plant.
More recently the process has been adopted in the UK for treatment of spent ion exchanger resins containing high levels of complexing agents. |
