A method has been developed for removing chromium from alkaline high-level radioactive tank waste.Removing chromium from these wastes is critical in reducing the volume of waste requiring expensive immobilization and deep geologic disposition.The method developed is based on the oxidation of insoluble chromium(III) compounds to soluble chromate using ferrate.This method could be generally INTERNATIONAL JOURNAL OF SCIENTIFIC detrimental to the environment and people living nearby ,.In the Philippines,most SSGM ball milling facilities have inadequately designed sedimentation tanks as its only treatment method before disposing of overflow wastewater .This effluent coming out from these tanks is not completelyLocally produced natural conditioners for dewatering of that available space in urban areas for the treatment of FS is a challenge.Settlingthickening tanks and drying beds are the most common treatment technologies for solidliquid separation and dewatering of FS,[10,11] however,they are very land intensive.
