摘要： A bio-inspired method for detoxifying contaminated water is disclosed. In the method, polydopamine, a mussel-inspired adhesive catecholamine was used as an adsorbent to effectively remove from contaminated water three major classes of toxic agents: heavy metal ions (e.g., Cr, Hg, Pb, Cu, and Cd), toxic organic species (e.g., 4-aminopyridine), and radioisotopes (e.g., Lutetium-177). Furthermore, the polydopamine adsorbent was regenerated by treatment with acid or hydrogen peroxide.

摘要： A device, method, and processor-readable medium for water quality detection and diversion are disclosed. Water entering a building's plumbing system is tested for impurities before it routes for consumption. Impurities in the water could include bacteria, viruses, chemicals, toxins, fertilizers, minerals, biological weapons, radioactive materials, and radioactive waste. Sensors are located throughout the device to check for impurities in the water as it travels through the building's plumbing. Certain sensors decide how to route the water through various treatments within the device. Treatments to the impure water could include multi-level filtration and heating/cooling cycles for a prescribed time period to reduce impurities below an EPA-approved threshold. If the water still retains impurities after treatment in the device, the device can decide to divert the water out of the building to prevent consumption and illness to building occupants.

摘要： The present disclosure relates, according to some embodiments, to systems and methods for removal of contaminants from water including, but not limited to, industrial wastewater, brackish water, municipal wastewater, drinking waters, and particularly waters obtained from fracking operations. For example, a method for purifying a feed water composition may comprise (a) contacting the feed water composition with an activated manganese dioxide to form an activated manganese dioxide-containing feed water composition, where the activated manganese dioxide was formed by contacting soluble organics with soluble permanganate ions (MnO4−) at a pH from about 5.5 to about 14; (b) increasing the pH of the activated manganese dioxide-containing feed water composition sufficient to form a contaminant precipitate and an alkaline solution, wherein the contaminant precipitate comprises at least some of the metal; (d) removing the contaminant precipitate from the alkaline solution to form a treated water, wherein the treated water is purified relative to the feed water composition. The activated manganese dioxide material may be formed in situ by adding the soluble permanganate ions to the feed water composition where the permanganate will react with the contained proper organic or a proper organic added to the feed water composition, such as glycerin. In the alternative, the activated manganese dioxide can be formed in vitro by reacting the soluble permanganate ions with the proper organic, and the resulting activated manganese dioxide can thereafter be added to the feed water composition. Optionally, the pH of treated water can be lowered, for example to a pH suitable for transportation or for further industrial use, such as liquid road salt. In addition, either or both the feed water composition and the treated water can be exposed to activated carbon. Further yet, the treated water can be exposed to ultraviolet (UV) light. The treated water is then suitable for industrial purpose, such as liquid road salt.

摘要： Systems and methods are provided for the removal and disposal of radium form an aqueous medium. The systems and methods include the removal of radium from a source by contact with either natural or synthetic zeolite. The spent zeolite is monitored for radiation levels and replaced with fresh zeolite when the level of radioactivity reaches approximately 9,000 pCi/g. Spent zeolite is disposed of at a low-level radioactive waste site. A system for monitoring and maintaining radium removal and disposal by an off-site provided is also disclosed.

摘要： Flow and product waste water from fracturing can be cleaned and reused utilizing a precipitation methodology incorporating, in part, a super critical reactor 30. Initially, the waste water is treated to remove solids, destroy bacteria, and precipitate out certain salts, such as barium, strontium, calcium, magnesium and iron. The waste water then can be passed through a radioactive material adsorption unit 20 to remove radium, as well as other radioactive materials, and then introduced into the super critical reactor 30. The super critical reactor is designed to bring the waste water to super critical conditions at a central portion of the reactor. This causes any dissolve solids, in particular sodium chloride and the like, to precipitate out of solution in the center 42 of the reactor 30 thereby avoiding scale formation on the walls of the reactor. A catalyst can be utilized to promote the breakdown of carbon bonds and promote the water/gas shift reaction. The effluent from the super critical reactor is then cooled and any formed gases separated from the remaining liquid. The remaining liquid can then be introduced back into the environment and the gases can be used to heat the super critical reactor.

摘要： An adsorbent is provided to adsorb ruthenium from aqueous solution for recovery and/or reuse or removal of said ruthenium, and a method for purifying, for example, sea water and/or water containing sodium ions, magnesium ions, calcium ions, chlorine ions or other ions, polluted with a radioactive element, using said adsorbent.The ruthenium adsorbent includes manganese in the form of oxides thereof. The adsorbent can further include at least one additional transition metal element other than manganese, such as copper. The adsorbent soaked in water removes radioactive ruthenium or the like through adsorption, and thereby can purify, for example, sea water and/or water containing sodium ions, magnesium ions, calcium ions, chlorine ions or other ions.
