AI Technical Summary

Problems solved by technology

However, the release of highly chlorine-contaminated water also exhibits a very significant intervention in native ecosystems
[0005] Therefore, the most advanced known methods and devices for ballast water purification also offer only low flexibility, reliability and / or environmental safety when treating ballast water
Furthermore, known methods and devices for ballast water treatment require relatively high maintenance consumption and do not provide sufficient protection against the spread of organisms in exotic ecosystems

Embodiment Construction

[0039] figure 1 An embodiment of a device for liquid purification is schematically shown.

[0040] The device 100 comprises two filter modules 10, each having the shape of a hollow cylinder and consisting of a stainless steel tube closed at both ends. At the upper end of each filter module there is an inlet 12 for the liquid to be purified and at the lower end a first outlet 14 for the liquid. In addition, on the pipe casing of the filter module 10, a second outlet 16 is provided near the upper end of the module.

[0041] A stainless steel membrane with pores of about 30 μm is provided inside the filter module 10 . The stainless steel membrane 18 also has the shape of a hollow cylinder, which is arranged substantially coaxially (ie concentrically in cross-section) in the stainless steel tube of the filter module 10 , wherein the diameter of the stainless steel membrane is smaller than that of the filter module 10 . The inlet 12 and the first outlet 14 are arranged approxima...

Abstract

The invention relates to an apparatus for purifying liquids, in particular for purifying ballast water.

Description

technical field [0001] The present invention relates to a device for purifying liquids, in particular ballast water. Background technique [0002] Ballast water is carried by seagoing ships to stabilize the ship and ensure its seaworthiness when sailing empty. For this purpose, sea or river water is contained in special ballast tanks or, in the now common case of double hulls, sea or river water is contained in cavities located between the two shell walls of the hull. By holding ballast water at a first location and releasing the same ballast water at a second location, the spread of organisms into exotic ecosystems often occurs (invasive species problem). [0003] To compensate, seagoing ships are usually equipped with coarse mechanical screens for filtering the carried ballast water. A disadvantage here is that the filters, which for example consist of grids of the pipe network, require regular maintenance and cleaning. [0004] In some cases, the ballast water is kept ...
