A liquid treatment system and a cleaning arrangement, wherein said liquid treatment system comprises at least one ultra-violet (UV) light treatment lamp arranged within an elongated protective UV-transparent sleeve provided along a central longitudinal axis A, said sleeve having an outer surface and an essentially circular cross-sectional shape; and a reactor configured to receive said sleeve, whereby a liquid treatment chamber for receiving liquid to be treated, is provided between an inner surface of the reactor and the outer surface of the sleeve; wherein said liquid treatment system further comprises at least one cleaning arrangement comprising at least one coil spring, which is wrapped around at least a part of a circumference of the sleeve such that a spring force of the at least one coil spring will press the coil spring towards the sleeve, wherein said cleaning arrangement is configured to be moved along the sleeve and the coil spring will clean the outer surface of the sleeve, wherein said cleaning arrangement comprises at least two coil springs which are mounted in a holder of the cleaning arrangement such that the coil springs together wrap over essentially the whole circumference of the sleeve.

Cleaning arrangement for a liquid treatment system

A liquid treatment system comprising at least one ultra-violet light treatment lamp arranged within an elongated protective UV-transparent sleeve provided along a central longitudinal axis A, said sleeve having an outer surface and an essentially circular cross-sectional shape; and an elongated reactor configured to receive said sleeve, whereby an elongated liquid treatment chamber for receiving liquid to be treated, is provided between an inner surface of the reactor and the outer surface of the sleeve; wherein said liquid treatment system further comprises at least one cleaning arrangement comprising at least one cleaning device, wherein said cleaning arrangement is configured to compress said cleaning device towards the outer surface of the sleeve and to transfer the cleaning device over the sleeve surface for cleaning the outer surface of the sleeve, wherein the at least one cleaning device comprises at least one metal braid.

Liquid treatment system

A liquid treatment system () comprising a liquid enclosure () having a main axis A, at least one ultra-violet (UV) light source () with an extension along said main axis and configured to emit UV light to a liquid in the liquid enclosure (). The liquid enclosure comprises at least one liquid section () with an extension along the main axis and structured to contain the liquid. The system () comprises swirl generating members () configured to generate a swirling motion of the liquid around a swirling axis S in the at least one liquid section () wherein the swirling axis is essentially parallel to the main axis, wherein the swirling motion is such that a controlled varying distance is induced to essentially all liquid elements of the liquid in relation to said light source () such that essentially all liquid elements are moved into high UV radiation zones closest said UV transparent wall (), to achieve uniform UV radiation of the liquid.

System for treating liquids by applying ultra-violet radiation

A liquid treatment module (), configured for ultraviolet (UV)-light treatment of a liquid () flowing through a first treatment chamber () defined as a first elongated circumferential hollow cavity () between an outer surface () of a first translucent inner sleeve () and an inner surface () of a first outer sleeve (') configured to enclose said first translucent sleeve (). The inner sleeve () is arranged to protect and include a UV-light treatment lamp (). The module comprises a module inlet connection () configured to receive liquid to be treated and a module outlet connection () configured to expel liquid treated by the liquid treatment module. The module comprises: &#x2014;first liquid flow guiding members (&#x2032;) configured to guide and direct a liquid flow () from said module inlet connection () into said first treatment chamber (), &#x2014;second liquid flow guiding members (&#x2032;) configured to guide and direct a liquid flow () from said first treatment chamber () into a second treatment chamber (&#x2032;), and &#x2014;third liquid flowing guiding members (&#x2032;) configured to guide and direct a liquid recirculation flow () from said second treatment chamber (&#x2032;) back into the first treatment chamber () again.
