Abstract:
Eine Vorrichtung zur Reinigung von Wasser umfasst ein Gehäuse (4) mit einem Rohwasserzulauf (5) und eine im Gehäuse (4) eingesetzte Kartusche (10), welche enthält: - eine erste Lage (1) aus einem elektroaktiven Adsorbermaterial mit einem in wässriger Umgebung elektrokinetischen Potential (Zeta-Potential), an dem sich im Wasser enthaltene Mikroorganismen, insbesondere Viren und Keime, durch Elektroadsorption anlagern, - eine zweite Lage (2) aus einem elektroaktiven Adsorbermaterial mit einem in wässriger Umgebung elektrokinetischen Potential (Zeta-Potential), an dem sich im Wasser enthaltene Mikroorganismen, insbesondere Viren und Keime, durch Elektroadsorption anlagern, - und eine zwischen der ersten Lage (1) und der zweiten Lage (2) angeordnete dritte Lage (3), welche ein Adsorbens enthält, an dessen Oberfläche sich im Wasser befindliche Partikel oder gelöste Stoffe durch physikalische und/oder chemische Adsorption anlagern, - wobei die Lagen (1, 2, 3) jeweils als Hohlzylinder ausgebildet und konzentrisch zueinander mit der ersten Lage (1) radial außen liegend angeordnet sind und wobei zwischen der Innenseite des Gehäuses (4) und der radial außen liegenden ersten Lage (1) ein mit dem Rohwasserzulauf (5) in Verbindung stehender Ringkanal (8) zur Verteilung des Rohwassers in der Kartusche (10) angeordnet ist. Diese Vorrichtung ermöglicht gleichzeitig eine Reinigung und eine Desinfizierung bzw. Sterilisierung von Wasser, wobei sowohl anorganische oder organische Verunreinigungen, wie z.B. Spurenstoffe und endokrine Disruptoren, als auch Mikroorganismen aus dem Wasser entfernt werden können.

Abstract:
A wastewater treatment system is provided comprising a first biological reaction zone, a second biological reaction zone and a membrane operating system. The first biological reaction zone is constructed and arranged to receive and treat the wastewater. The second biological reaction zone includes a separation subsystem and is constructed and arranged to receive effluent from the first biological reaction zone. A suspension system for adsorbent material is provided in the second biological reaction zone. The membrane operating system is located downstream of the second biological reaction zone and is constructed and arranged to receive treated wastewater from the second biological reaction zone and discharge a membrane permeate.
Abstract:
The invention relates to a sewage treatment system, comprising a separation unit (12) adapted to separate sewage sludge from sewage to obtain pretreated sewage; heat generation means (20), such as a two-stage furnace, adapted to generate heat from separated sewage sludge; a purifier unit (16, 18) adapted to evaporate pretreated sewage and re-condense evaporated water contained therein; and first heat transfer means (24) adapted to transfer heat from the heat generation means to the purifier unit, wherein the transferred heat is used to evaporate pretreated sewage. The invention further relates to a sewage treatment method.
Abstract:
The invention provides a method and device for decomposing environmental pollutants, capable of decomposing organic halogen compounds, etc., which are environmental pollutants in a short time and in large quantities to such a low concentration degree that allows them to be discharged as drainage into a sewage pipe or the like and also capable of decomposing organic substances, nitrogen, phosphorous, etc., which are hard to oxidation-decompose. To a sample solution (20) in a reaction vessel (10a) storing an aqueous solution containing environmental pollutants, a vibrator (30a) placed on the central bottom of the reaction vessel (10a), for example, radiates ultrasonic waves (50), and at the same time, ultraviolet lamps (40a) disposed on the peripheral edge within the reaction vessel (10a) radiate ultraviolet rays. On this occasion, the ultraviolet lamps (40a) are disposed at positions where they substantially do not interfere with the path of travel of ultrasonic waves (50).
Abstract:
Basalt selectively adsorbs organic toxic materials, such as dioxins, furans, poly- chlorinated biphenyls (PCBs), bis(2-ethylhexyl)phthalate, arsenic, mercury, chromium, copper, nickel, zinc, cadmium, lead, and the like, from substances such as sediment, which contains water and the toxic materials.
Abstract:
Disclosed are methods, apparatuses and systems for the remediation of contaminated soils, groundwater, water, and/or waste using a combination of reagents. The disclosed methods may be used to treat various recalcitrant halogenated substances, such as perfluoroalkyls and polyfluoroalkyls. Particular combinations of reagents that may be used in the disclosed methods include but are not limited to: (1) persulfate, oxygen and ozone; (2) persulfate, salt, oxygen and ozone; (3) persulfate, phosphate, and/or oxygen; (4) persulfate, phosphate, oxygen and ozone; (5) persulfate, phosphate, salt and oxygen (6) persulfate, phosphate, salt, oxygen and ozone; (7) oxygen and salt; and (8) air and salt. The disclosed methods may enhance destruction of organic contaminants in the liquid phase and may also control the rate of aerosol or foam formation relative to the rate of chemical oxidation and/or reduction/transfer.
Abstract:
The present invention features compositions and methods for reducing the concentration of an endocrine disrupting agent in an aqueous solution. We describe compositions comprising various polymeric resins. The methods can be used to reduce the concentration of endocrine disrupting agents, including estrogens, perfluorinated compounds and bisphenol A in an aqueous solution.
