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.
