Product Name: L-Lactic Acid Clarification by Ceramic Membrane Filtration Model NO.: JIUWU ceramic membrane CMF19040 Performance: Efficient Filtration Style: Vertical Motive Force: Pressure Usage: Food Upgrade Type: Ceramic Membrane Trademark: JIUWU HI-TECH Origin: China Product Description Ceramic membrane crossflow technology was chosen for food and feed ingredients, state of the art facility for its ability to reliably deliver the highest filtrate quality regardless of broth characteristics. Unlike centrifugation, where cell size and density as well as fluid viscosity influence the separation efficiency, membrane separation offers an absolute physical barrier that will always provide the optimum separation.Additionally, ceramic technology provided a solution which could operate without incurring the storage, handling and waste typical of filter aid-based precoat technology. An additional advantage of this solution is the ability to further use the product retentate stream, for example by drying it for use as animal feed.Large diameter membrane channels were selected to handle the high feed spin solids. This resulted in the highest possible VCF and a retentate concentration in excess of 45 %. To further maximize recovery, diafiltration was used and resulted in an additional increase in the final yield of over 25 %.+++ organic acidsOrganic acids: lactic acid, citric acid, itaconic acid, succinic acid and so onLactic acid is traditionally used in the food,pharmaceutical, andchemical industries, andrecently its potential for producing biocompatibleand biodegradable plastics has beenactively pursued.Approximately half ofthe world's supply of lactate is produced byfermentation.To replace plate and frame filter press and precipitation with ceramic membrane filtration is successfullyapplied in current L-lactic acid production industry. Permeation after ceramic membrane clarification entersinto non-crystallizing process and then goesto discoloring. During discoloringprocess, activated carbon is used for adsorptiont proved that activated carbon usage has been greatly decreased by ceramic membrane filtration.
