AN ADVANCED LIQUID WASTE TREATMENT SYSTEM USING A HIGH EFFICIENCY SOLIDIFICATION TECHNIQUE

Description: An advanced system using High Efficiency Solidification Technology (HEST) was developed to treat PWR liquid waste and the first unit is operating in Taiwan (1) and a detailed design is being carried out for the second unit in Japan. The HEST system consists of two subsystems, a super-concentration subsystem and a solidification subsystem. The super-concentration subsystem is able to concentrate the waste solution to a total boron content as high as 130,000 ppm prior to solidification. The highe… more

Development of Wet-Oxidation Treatment System for Filter Backwash Sludge and Ion Exchange Resins

Description: Decomposition of organic compounds contained in filter backwash sludge and spent ion exchange resins is considered effective in reducing the waste volume. A system using the wet-oxidation process has been studied for the treatment of the sludge and resins stored at Tsuruga Power Station Unit 1, 357MWe BWR, owned by The Japan Atomic Power Company. Compared with various processes for treating sludge and resin, the wet-oxidation system is rather simple and the process conditions are mild. Waste sa… more

Conditioning Technology for Radioactive Waste Resulted From the Treatment of Liquid Waste From the Romanian Nuclear Power Plant

Description: For the conditioning of spent resins contaminated with radionuclides, such as: 137Cs, 134Cs, 60Co, 58Co, 57Co, 54Mn, etc., techniques of direct immobilization in cement, bitumen and organic polymers have been tested. The selected process was the bituminization using industrial bitumen, I 60-70, made in Romania, which had very good characteristics. The paper presents stages of the research project, technical conditions for the process and advantages of the bituminization of spent resins.

BIOTIGER, A NATURAL MICROBIAL PRODUCT FOR ENHANCED HYDROCARBON RECOVERY FROM OIL SANDS.

Description: BioTiger{trademark} is a unique microbial consortia that resulted from over 8 years of extensive microbiology screening and characterization of samples collected from a century-old Polish waste lagoon. BioTiger{trademark} shows rapid and complete degradation of aliphatic and aromatic hydrocarbons, produces novel surfactants, is tolerant of both chemical and metal toxicity and shows good activity at temperature and pH extremes. Although originally developed and used by the U.S. Department of Ene… more
