A mobile processing system is disclosed for the removal of radioactive contaminants from nuclear process wastewater. The system is fully scalable, modular, and portable allowing the system to be fully customizable according to site-specific remediation requirements. It is designed to be both transported and operated from standard sized intermodal containers or custom designed enclosures for increased mobility between sites and on-site, further increasing the speed and ease with which the system may be deployed. Additionally, the system is completely modular wherein the various modules perform different forms or stages of wastewater remediation and may be connected in parallel and/or in series. Depending on the needs of the site, one or more different processes may be used. In some embodiments, one or more of the same modules may be used in the same operation.

A dissolved air floatation apparatus including an ultrafine bubble-containing liquid production device and a dissolved air floatation tank. The ultrafine bubble-containing liquid production device includes a gas-liquid mixing unit and a bubble-containing liquid separation device. The bubble-containing liquid separation device swirls a liquid containing ultrafine bubbles and larger bubbles in a storage tank to concentrate the liquid that contains the ultrafine bubbles and the liquid that contains the larger bubbles to a central part of the swirling flow followed by discharge. A pressurized ultrafine bubble-containing liquid is mixed in a raw liquid containing a subject to be cleansed and is poured into the dissolved air floatation tank to cause a suspended substance and a dissolved component in the raw liquid to be adsorbed on an interface of fine bubbles and be floated in the dissolved air floatation tank to be extracted.

The invention relates to an apparatus which comprises a pyrolytic plasma reactor (1) with: a conical head (8), on which are mounted: inlets (2, 3, 4); a first plasma torch (6); and first gas outlet (5); a cylindrical reaction chamber (9), under the head (8), and which comprises: a side wall (11) with a refractory covering (12); and a bottom (16), o with a decreasing cross-section, for receiving lavas; a base (10), for supporting the head (8) and the reaction chamber (9); and discharge means in the reaction chamber (9) and/or in the base (10) for discharging the lavas. By keeping the first torch (6) lit, the method comprises directing solid, liquid and gaseous hazardous waste towards the central portion of the plasma jet from the first torch (6), with no contact between the various types of hazardous waste. The dissociation conditions are improved by the invention.
