Abstract:
The aim of the invention is to provide a device and a method for producing sterile water by means of a cross-flow liquid sterile filter without the closure of the water line during the filtration process, said closure being bacteria-tight according to the prior art of point-of-use potable-water sterile filtration, and without the negative consequences associated with said closure. Said aim is achieved according to the invention by the simultaneous, continuous discharge of the germ-containing retentate from the cross-flow liquid sterile filter during the filtration and the disinfection thereof in a disinfecting apparatus. The result of the interaction of all components according to the invention is therefore a device and a method by means of which sterile and endotoxin-poor water can be produced without bacteriological closure of the water line, without interruption of the filtration at short intervals, and with maximum hygienic safety and which thus no longer have all the stated disadvantages of the POU sterile filters described according to the prior art and used in practice.
Abstract:
The invention relates to a method for the regeneration of deNOx catalysts with a reduced activity caused by the accumulation of phosphor and phosphorous compounds. The method is characterized in that the catalysts are treated with an essentially aqueous solution of water-soluble alkaline reacting alkaline earth salts, ammonium hydroxide, or alkaline reacting ammonium salts, or water-soluble organic amines with an approximate pK value ranging between 2.5 and 5.5 and that the excess alkali is neutralized by subsequent treatment with inorganic or organic acids.
Abstract:
The invention entails a sanitary wash area which includes a wash basin or a shower basin or bath or birthing tubs (1), whose water supplies (2) are provided with sterile filters (4) for sterilizing tap water and whose water outlets (3) are furnished with self-disinfecting siphon traps (5). In addition, the sanitary wash area may be furnished with one or more UV lamps (6), which emit ultraviolet light, for the surface disinfection of the outlet of the sterile filter (7) and the outer area of the inlet of the self-disinfecting siphon trap (5) as well as for the intensive sterilization of the sink or tub surface.
Abstract:
The self-disinfecting drain trap is an arrangement for the automatic cleaning and disinfecting of drain traps in drain channels. The cleaning and disinfection take place automatically during normal usage and without interruption of the operation of the drain trap. They take place by means of a novel combination for drain traps of electromechanical oscillation, preferably ultrasound, heating the interior space of the drain trap and heating the confining liquid and preventing growth on the inner wall by means of a growth-inhibiting and antimicrobially effective coating. The danger of recontamination of sanitary apparatuses and devices and therewith also of the ambient air by microorganisms from wastewater pipelines is effectively countered therewith.
Abstract:
A process for regenerating catalytic converters includes placing the catalytic converter in motion in a cleaning solution and subjecting it to ultrasonic treatment. Catalytic converters so treatable include those which have ceramic bodies and which catalyze the reduction of nitrogen oxides into molecular nitrogen and which substantially include titanium oxide TiO2, tungsten oxide WO3, and active component vanadium pentoxide V2O5.

Abstract:
The invention relates to a self-disinfecting drain trap in wastewater drains, having an automatic cleaning through an electromagnetic oscillator and an automatic disinfection through heat, UV-C radiation, antibacterial coating, or ultrasound. The inner wall of the drain trap may be coated with a titanium dioxide nano-coating, on which a catalytic oxidizing reduction of organic substances that can be oxidized takes place, and microorganisms are killed. The titanium dioxide nano-coating may be activated through irradiation with at least one light source located inside or outside the drain trap. When the cleaning and disinfection functions are inactive, a retrograde microbial contamination of the barrier fluid is prevented, both on the part of the wastewater drain as well as through the ambient air, through the oxidizing disinfecting effect of the titanium dioxide nano-coating.
