Organic acids: lactic acid, citric acid, itaconic acid, succinic acid and so on Lactic acid is traditionally used in the food, pharmaceutical, and chemical industries, and recently its potential for producing biocompatible and biodegradable plastics has been actively pursued.Approximately half of the world’s supply of lactate is produced by fermentation.


To replace plate and frame filter press and precipitation with ceramic membrane filtration is successfully applied in current L-lactic acid production industry. Permeation after ceramic membrane clarification enters into non-crystallizing process and then goes to discoloring. During discoloring process, activated carbon is used for adsorption t proved that activated carbon usage has been greatly decreased by ceramic membrane filtration.
