Designed to provide high efficiency removal of naturally-occurring uranium from groundwater supplies, the packaged, pre-engineered AdEdge AD92 system features a twin 54-inch vessel configuration with a design flow of 250 gpm in parallel configuration. ...
In order to develop an effective and economical method for removing low concentration radioactive wastewater of uranium, the biomass of ‘CMCC(F)-98003’ Aspergillus niger was investigated in a batch system. The maximum uranium adsorption capacity of 12.5 mg g−1 was obtained at the initial uranium concentration of 0.75 mg L−1. ...
U(VI) adsorption was strongly pH dependent, and the optimum pH for U(VI) removal was 5.5. Isotherm adsorption data displayed good correlation with the Langmuir model, with a maximum monolayer adsorption capacity of 171.52 mg/g. ...
Spectroscopic analyses showed that uranium was adsorbed in the porous inside structure of the biosorbent. ...
The optimal pH for quantitative removal is 4.0–8.0, sorbent amount is 20 mg, contact time is 20 min and the retention capacity is 120 mg of uranyl ion per g of IIP. The IIP prepared demonstrated superior selectivity towards coexisting cations and therefore it can be used for selective removal of uranium from complex matrices.Keywords: complex ...
Treatment System Designed to provide high efficiency removal of naturally-occurring uranium from groundwater supplies, the packaged, pre-engineered AdEdge AD92 system featured a twin vessel configuration flowing 160 gpm in parallel or 80 gpm per vessel. ...
AdEdge was contacted by Otter Creek Engineering in June 2009 to assist the School in providing a packaged treatment system for uranium removal that complied with the Vermont Department of Health’s drinking water regulations. ...
The adsorption features of synthetic magnetite nanoparticles have been investigated for removal of uranyl ions from nitric solutions. These magnetic nanoparticles can be used to adsorb contaminants in wastewater and can subsequently be removed from the medium by a magnetic process because of their superparamagnetic behaviour. ...
Its adsorption performance was evaluated by the adsorption isotherm models of Langmuir and Freundlich for uranium ions, and the desorption behaviour using carbonate and oxalate ions was investigated. ...
The regenerative AD92 IX ion exchange approach was the preferred and most cost-effective option for this site, and this technology has been designed to provide high efficiency removal of naturally-occurring uranium from groundwater supplies. The AD92 IX media is a strong base-anion exchange resin used to selectively remove naturally-occurring ...
The uranium treatment system is rated for a maximum design flow of 200 gpm. ...
The macrofungus Ganoderma lucidum was employed for removing and recovering uranium (VI) from low-level (10-100 mg/L) uranium wastewaters. ...
Designed to provide high efficiency removal of naturally-occurring uranium from groundwater supplies, the packaged, pre-engineered AdEdge AD92 system features a twin 54-inch vessel configuration with a design flow of 250 gpm in parallel configuration. ...
However, in view of past experiences it is feasible to take into consideration some generic threat scenarios, potentially resulting in loss of control over the nuclear material, respectively its by-products, such as: illegal mining of an officially closed uranium mine; covert diversion of uranium ore whilst officially mining another ore; covert transport of ...
