  • Patent number: 8999254
    Abstract: Apparatus and a method for decomposing a body of a deceased person, as an alternative to traditional cremation. The apparatus includes a primary vessel where the body is treated with a highly basic solvent to render the body into skeletal remains and liquid remains. A clamp is applied to the skull during processing for solvent access to the skull. A secondary vessel is used to receive the liquid remains from the primary vessel and further treat them. During this further treatment, the skeletal remains left in the primary vessel after the liquefied portion has been transferred to the secondary vessel, can be treated to be decolorized and deodorized, and then returned to the decedent's next of kin as ash-like material.

  • Patent number: 8993827
    Abstract: A method and apparatus for the stabilization and safe removal of buried waste that is tested and classified as being transuranic or not transuranic waste and disposed accordingly. The buried waste (usually in vertical pipe units) is enclosed in a casing and ground and mixed with the surrounding soil. This process allows for chemical reactions to occur that stabilizes the mixture. The entire process is contained within the casing to avoid contamination. In situ or external testing is done for radio isotopes to classify the waste. If it is classified as transuranic the waste is removed in a controlled way into a retrieval enclosure and disposed off in drums. If the waste is not transuranic then grout is introduced into the mixture, allowed to set and the resulting monolith is removed and buried in trenches.

  • Patent number: 8444928
    Abstract: A method for treating waste water is provided, in which a wastewater is treated through a distilling process to obtain a distilled liquid, and then a reactant is added into the distilled liquid during the distilled liquid flowing to a liquid collecting tank, such that the reactant reacts with the distilled liquid by utilizing the residual temperature of the distilled liquid to form a processed liquid. Meanwhile, a system for wastewater treatment is also provided, which includes a distillation unit, a guiding unit, a means for adding the reactant, and a collecting unit. Since the present invention utilizes the residual temperature of the distilled liquid for the need of the reaction, an additional heat source is unnecessary, such that the consumption of energy can be greatly reduced.

  • Patent number: 8097765
    Abstract: Parts, structural components, etc. that have their surfaces contaminated by radioisotopes in the accelerators, nuclear reactors, RI product manufacturing factories, nuclear fuel factories, nuclear fuel reprocessing factories, etc. are decontaminated by non-thermal laser peeling without suffering re-melting, re-diffusing and re-contaminating such that upon non-thermal laser irradiation, areas near the irradiated surface are evaporated and removed faster than the heat generated in the irradiated surface is transmitted to nearby areas.

  • Patent number: 8047978
    Abstract: A new High-Throughput Explosive Destruction System is disclosed. The new system is comprised of two side-by-side detonation containment vessels each comprising first and second halves that feed into a single agent treatment vessel. Both detonation containment vessels further comprise a surrounding ventilation facility. Moreover, the detonation containment vessels are designed to separate into two half-shells, wherein one shell can be moved axially away from the fixed, second half for ease of access and loading. The vessels are closed by means of a surrounding, clam-shell type locking seal mechanisms.

  • Patent number: 7878100
    Abstract: An apparatus useful in the removal of toxic materials from toxic weapon projectiles has a base, a projectile retaining container and a ram. The projectile retaining container has a projectile retainer opening, a ram opening and a drain opening. The projectile retaining container is adapted to retain a toxic weapon projectile in the projectile retainer opening. The ram is adapted to extend into a toxic weapon projectile disposed within the projectile retaining container to crush the projectile's burster well and to thereby release toxic materials to the drain opening in the projectile retaining container. The ram alternatively includes high pressure water nozzles for breaking up any coagulant particles and for thoroughly rinsing the interior side walls of the toxic weapon projectile.

  • Patent number: 7854107
    Abstract: The present invention discloses a solution for disposing waste having potentially hazardous airborne emissions. The solution can include a step of receiving waste through an aperture of a disposal unit exhibiting a closed environment. The received waste can be placed within an air tight disposal container. An opening of the disposal container can be sealed to separate the disposal container from the remainder of the substantially closed environment. Air included in the remainder of the substantially closed environment can be captured and placed in a holding unit. The captured air can be ejected from the holding unit into the air tight disposal container. The disposal container containing the received waste and the ejected air can be sealed. The disposal unit can be thereafter opened so that the sealed disposal container is able to be discarded.

  • Patent number: 7812210
    Abstract: The invention relates to a refuse treatment plant (1) with a closed construction, which permits the aerobic degradation of organic material, for example in refuse comprising biodegradable fractions. The refuse treatment plant (1) comprises a bay (5) with an aeration and deaeration installation. At least one refuse treatment chamber (16), which is connected to the bay (5) via an opening (7) in the bay wall, is located on at least one external face of the bay wall (6). The refuse treatment chamber (16) is configured by a cover tarpaulin (30), which is provided with a raising and lowering device (20), is water-and particle-tight but permeable to air and water vapour. The cover tarpaulin (30) comprises an edge (32), which is attached to the bay wall (6) and to the ground (50) in a rigid and airtight manner by means of a fixing device (50). The raising and lowering device (20) can be configured with the aid of a pneumatic support structure (22) consisting of inflatable tubes (23).

  • Patent number: 7798951
    Abstract: An apparatus for disposal of low-level surface radioactive pollutants has a container body which center has accommodating space with opening at its top. Around the accommodating space there is a layer of barrier space for holding water. At the periphery of the barrier space there is a non-barrier hollow channel for the accommodating space to connect outside. A rotating disk is located at the bottom of the accommodating space in the container body for holding and turning the low-level radioactive waste to be treated and also facilitating the worker to pass through the non-barrier hollow channel for cleaning task.
