Abstract
Official abstract text for this publication.
Provided is a method for regenerating a liquid to be treated, the method includes bringing a lactic acid adsorbent that contains a Mg—Al-based layered double hydroxide having Mg 2+ and Al 3+ as constituent metals, and an ammonia adsorbent having L-type zeolite, into contact with the liquid to be treated that contains lactic acid and ammonia, to remove lactic acid and ammonia in the liquid to be treated.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for regenerating a liquid to be treated, the method comprising: bringing a lactic acid adsorbent that contains a Mg—Al-based layered double hydroxide having Mg 2+ and Al 3+ as constituent metals, and an ammonia adsorbent having L-type zeolite, into contact with the liquid to be treated that contains lactic acid and ammonia, to remove lactic acid and ammonia in the liquid to be treated, wherein the liquid to be treated is a culture liquid of at least either cell or microorganism that contains glucose, and wherein an amount of consumption of each of the lactic acid adsorbent and the ammonia adsorbent is adjusted so that a concentration thereof relative to the liquid to be treated is 0.05 g/mL or higher and 0.1 g/mL or lower for both the lactic acid adsorbent and the ammonia adsorbent. 2 . A regenerating agent for a liquid to be treated, the regenerating agent comprising: a lactic acid adsorbent that contains a Mg—Al-based layered double hydroxide having Mg 2+ and Al 3+ as constituent metals; and an ammonia adsorbent having L-type zeolite, wherein the regenerating agent is configured to remove lactic acid and ammonia in the liquid to be treated, upon being bought into contact with the liquid to be treated that contains lactic acid and ammonia, wherein the liquid to be treated is a culture liquid of at least either cell or microorganism that contains glucose, and wherein an amount of consumption of each of the lactic acid adsorbent and the ammonia adsorbent is adjusted so that a concentration thereof relative to the liquid to be treated is 0.05 g/mL or higher and 0.1 g/mL or lower for both the lactic acid adsorbent and the ammonia adsorbent.
