Development of a Lactic Acid Recovery System Using Ammonia from a Fermentation Broth

Abstract

In order to lower the price of polylactic acid, it is necessary to reduce the energy required to produce energy lactic acid, which is its main material. In this work, we focused on a lactic acid recovery system after lactic acid fermentation, and proposed a new recovery process which combines the reverse osmosis (RO) method with ammonia removal method. Results shows that more than 90% of the glucose and ammonia were removed.
