Abstract: A method for processing chemical cleaning solvent waste that combines evaporation, purification, and detoxification. The method is mobile and thus allows the processing to be done at the site of the cleaning where the entire processing can be completed. Evaporation produces a concentrated solvent and vapor and gas. The concentrated solvent is detoxified to produce a dry residue for long term storage or disposal and a liquid that is filtered and then released to the surrounding environment. The vapor and gas are scrubbed and condensed to produce a gas that is suitable for release and a distillate. The distillate is purified by filtration and reverse osmosis to produce a distillate that is suitable for release.

Abstract: An ion exchange resin regeneration apparatus. A nine compartment module has two end anode electrode compartments and a center cathode electrode compartment. These three compartments contain a mixture of cation and anion resin. The two end compartments are lined by cation membranes while the center compartment is lined on both sides by anion membranes. All but two of the remaining compartments are provided with cation or anion exchange resin and opposing cation and anion membranes in an arrangement whereby a resin slurry may be consecutively directed through two of the compartments for processing.

Abstract: A non-intrusive vibration measurement system and method using commercial ultrasonic instruments together with digital signal filtering and analysis techniques is adapted to quantitatively detect vibrations as small as 0.04-inch peak-to-peak. The system and its methodology is used for in-service vibration monitoring of internal components of check valves, pumps, nuclear reactors, steam generators and heat exchangers, especially when the vibration frequency is too low for quantitative analysis by accelerometers and when the strain induced is too low for strain gauge analysis, and when the vibrating component is in an "encased" environment.
