This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
淊 combines 氵 (water) with 臽, which likely contributes the sound. The exact historical development and original meaning are uncertain.
Water 氵 beside 臽 suggests something related to water, but the specific meaning is unclear. Picture water flowing into a pit or hollow shape.
For カン, imagine a can of water being poured into the hollow shape on the right: can -> カン.
