Benefits of technology
The patent describes an apparatus and method for heating and directing fluids in a piping system. The technical effect is the ability to control the temperature and flow of fluids in a more precise and efficient manner, which can improve the overall performance and efficiency of the system.
Problems solved by technology
Validation of a static decontamination process is challenging, as the temperature distribution may be compromised due to various reasons such as air pouches and type of heating.
Furthermore, kill tanks, being pressure vessels, require regular inspection, and their energy requirements and space requirements are large.
Since the liquid effluent comprises contaminants such as organic matter and scaling agents, a continuous decontamination system has the drawback that the heating arrangements tend to soil the inner surfaces of the system with a contaminant layer.
Thus frequent chemical washing is required.
The performance of the static systems is difficult to validate, and the systems are expensive as well as time- and energy inefficient.
Then again, the continuous systems may require frequent chemical cleaning, for example due to heating arrangements and very long piping runs, and include moving parts prone to fault and requiring service.
This branch is a contamination risk in itself, and adds complexity to the system.

Embodiment Construction
[0039]In the following description, like reference signs denote like elements.
[0040]FIG. 1 shows a schematic example presentation of an apparatus according to an embodiment of the invention. The effluent decontamination apparatus 100 comprises a first inlet A configured to connect to a supply of motive fluid, such as steam, and a second inlet B configured to connect to a source of effluent, e.g. biological effluent, to be decontaminated. The apparatus 100 further comprises an outlet C for discharging the treated, i.e. decontaminated effluent into for example a drain. A skilled person appreciates that the inlets and the outlet are realized in a conventional manner, and that the source of the effluent is either a direct connection to a process of the facility the effluent of which is processed or the effluent is supplied from an intermediate storage such as a storage container or a transport vessel. Furthermore, the skilled person appreciates that instead of or in addition to a direct...

An apparatus and method for decontamination of effluent, comprising 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.
Description
TECHNICAL FIELD[0001]The present invention generally relates to decontamination of effluents. The present invention relates to any effluent where heat treatment can reduce or eliminate any undesired effect, such as chemical, physical, biological reaction or activity (pathogen inactivation, protein denaturing, prion inactivation etc.). In particular, but not exclusively, the present invention relates to decontamination of effluent liquid from biologically contaminated areas. The present invention can also be used as part of a system for chemical treatment of effluents.BACKGROUND ART[0002]Effluent decontamination is carried out in order to inactivate micro-organisms—including pathogens—present in liquid effluents from sources such as research laboratories, pharmaceutical or biopharmaceutical production plants and further bio-contained areas. The decontamination is effected with the principles of sterilization, i.e. high temperature is applied for a sufficient time to achieve a reducti...
