preheating boiler feed-water or accumulating preheated boiler feed-water F22D) - C02F 1/041: {by means of vapour compression} - C02F 2101/30: Organic compounds - C02F 2303/04: Disinfection - C02F: TREATMENT OF WATER, WASTE WATER, SEWAGE, OR SLUDGE (separation in general B01D; special arrangements on waterborne vessels of installations for treating water, waste water or sewage, e.g. for producing fresh water, B63J; adding materials to water to prevent corrosion C23F; treating radioactively-contaminated liquids G21F9/04; regeneration of reactants for recirculation into processes, see the relevant places for the processes) ## Abstract An apparatus and method for decontamination of effluent, includes connecting a first ejector to source of a first motive fluid, directing from the first ejector first motive fluid into piping connected to a source of effluent thus causing the effluent to stream in the piping and simultaneously causing the effluent to be heated, and controlling the directing of the first motive fluid in such a way that a predetermined thermal effect is achieved. ## Claims ### Claim 1 An apparatus for decontamination of effluent, comprising: a first inlet configured to be connected to a source of motive fluid; a second inlet configured to be connected to a source of effluent; an outlet-configured for discharging a treated effluent; piping connecting the second inlet and outlet; and a first ejector configured to direct the motive fluid from the first inlet into the piping connected to the second inlet thus causing the effluent to stream from the second inlet towards the outlet, and simultaneously causing the effluent to mix with the motive fluid and be heated to a predetermined temperature to achieve a predetermined thermal effect; wherein the apparatus is configured to direct pulses of the motive fluid to remove air from the apparatus prior to causing the effluent to flow in the piping. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the motive fluid from the first inlet is a first motive fluid, further comprising: a treatment tank positioned between the second inlet and the outlet and configured to hold the effluent; and a second ejector configured to cause emptying the treatment tank by directing a second motive fluid from a third inlet into piping connecting the treatment tank to the outlet. ### Claim 3 (depends on 1) The apparatus of claim 1, further comprising a further ejector configured to direct the motive fluid from the first inlet into the stream of effluent downstream from the first ejector thus causing the effluent to be heated further. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the apparatus is configured to cause the effluent to stream from the second inlet only in the direction of the outlet so that the effluent is inhibited from returning to the source of the effluent or to the second inlet. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the apparatus further comprises a temperature probe suitable to measure the temperature of the effluent being decontaminated. ### Claim 6 (depends on 1) The apparatus of claim 1, further comprising a first valve suitable to regulate the motive fluid supplied from the first inlet and a second valve suitable to regulate the effluent supplied from the second inlet. ### Claim 7 (depends on 1) The apparatus of claim 1, further comprising a temperature probe suitable to measure the temperature of the effluent mixed with the motive fluid supplied from the first inlet. ### Claim 8 An apparatus for decontamination of effluent, comprising: a first inlet configured to be connected to a source of steam; a second inlet configured to be connected to a source of effluent; an outlet configured for discharging the effluent; piping connecting the second inlet and outlet; and a first ejector configured to direct steam from the first inlet into the piping connected to the second inlet thus causing the effluent to stream from the second inlet towards the outlet, and simultaneously causing the effluent to mix with the steam and be heated; wherein the apparatus is configured to remove air from the apparatus with pulses of steam prior to causing the effluent to flow in the piping. ### Claim 9 (depends on 8) The apparatus of claim 8, further comprising: a treatment tank positioned between the second inlet and the outlet and configured to hold the effluent; a second ejector configured to cause emptying the treatment tank by directing a second motive fluid into piping connecting the treatment tank to the outlet. ### Claim 10 (depends on 8) The apparatus of claim 8, further comprising a third ejector configured to direct steam from the first inlet into the stream of effluent downstream from the first ejector thus causing the effluent to be heated further. ### Claim 11 (depends on 8) The apparatus of claim 8, wherein the apparatus is configured to cause the effluent to stream from the second inlet only in the direction of the outlet so that the effluent is inhibited from returning to the source of the effluent or to the second inlet. ### Claim 12 (depends on 8) The apparatus of claim 8, wherein the apparatus further comprises a first valve for regulating the supply of the steam and/or a second valve for regulating the supply of the effluent. ### Claim 13 (depends on 8) The apparatus of claim 8, wherein the apparatus further comprises a temperature probe suitable to measure the temperature of the effluent being decontaminated.
