Document Type and Number:
WIPO Patent Application WO/2022/050271
Kind Code:
A1
Abstract:
This method for regenerating a liquid to be treated comprises bringing a lactic acid adsorbent 4, which contains a Mg-Al-based layered double hydroxide containing Mg2+ and Al3+ as constituent metals, and an ammonia adsorbent 5, which contains L-type zeolite, into contact with a liquid to be treated, which contains lactic acid and ammonia, and removing the lactic acid and the ammonia from the liquid to be treated.
