Abstract
A water treatment device including a first hydrocyclone and a biocidal fluid injector is described. The first hydrocyclone has an internal space, a water inlet for supplying water into the internal space, a base outlet for discharging at least a part of the water, and an apex outlet. The biocidal fluid injector is configured to inject a biocidal fluid into the internal space for eliminating organisms present in the water. The biocidal fluid injector is positioned such that a pressure within the injected biocidal fluid is lower than a head pressure of the first hydrocyclone.
Claims17
A water treatment device comprising a first hydrocyclone and a biocidal fluid injector;
- the first hydrocyclone having an internal space, a water inlet for supplying water into the internal space, a base outlet for discharging at least a part of the water, and an apex outlet;
- and
- the biocidal fluid injector being configured to inject a biocidal fluid into the internal space for eliminating organisms present in the water, wherein the biocidal fluid injector is positioned such that a pressure within the injected biocidal fluid is lower than a head pressure of the first hydrocyclone.
A ballast water system comprising a ballast water tank and a water treatment device the water treatment device, including:
- a first hydrocyclone and a biocidal fluid injector;
- the first hydrocyclone having an internal space, a water inlet for supplying water into the internal space, a base outlet for discharging at least a part of the water, and an apex outlet;
- and
- the biocidal fluid injector being configured to inject a biocidal fluid into the internal space for eliminating organisms present in the water, wherein the biocidal fluid injector is positioned such that a pressure within the injected biocidal fluid is lower than a head pressure of the first hydrocyclone;
- and
- the ballast water tank being connected to the water treatment device so as to allow for a transfer of water in at least one direction.
A water treatment method comprising:
- feeding water into a water treatment device, the water treatment device, including:
- a first hydrocyclone and a biocidal fluid injector;
- the first hydrocyclone having an internal space, a water inlet for supplying water into the internal space, a base outlet for discharging at least a part of the water, and an apex outlet;
- and
- the biocidal fluid injector being configured to inject a biocidal fluid into the internal space for eliminating organisms present in the water, wherein the biocidal fluid injector is positioned such that a pressure within the injected biocidal fluid is lower than a head pressure of the first hydrocyclone.
