Customised Integrated Solution

Amino Acid

Amino acid is a common name for a class of organic compounds containing amino groups and antelope groups, and there are more than 300 kinds of natural amino acids, of which about 22 kinds of amino acids are needed by the human body. Suntar's integrated separation solutions have been successfully applied in a variety of amino acid production processes, such as lysine, tryptophan, threonine, arginine, glutamine, leucine, valine, isoleucine, homoserine, methionine, citrulline, etc.

  • Fermentation broth is filtered with membrane to remove all bacteria, solid proteins, colloids and other insoluble content. On top of that, this removes most of the macromolecules, such as protein, polysaccharides, etc. This clarifies the resin feed increasing the utilization rate of resin while solving most of the sewage problems.
  • Continuous ion-changer moving bed instead of fixed bed reduces resin, water and chemical consumption.
  • A variety of membrane separation technology are applied to recover mother liquor, recycle waste liquid and reclaim water.

Threonine

01

APPLICATION

Threonine requires higher filtrate quality from ceramic membrane separation than other amino acids. Suntar developed threonine specific ceramic membrane with high precision and high resistance to abrasion.

Lysine

01

APPLICATION

Membrane filtration produces clear filtrate with 15% increased resin equivalent weight.
Less impurities in the pillar reduces the amount of water needed for resin regeneration which increase the resin lifespan and total yield.
Membrane retains bacteria and protein in the fermentation broth which is then dried and processed into 65% lysine product.
Ion-exchange continuous moving bed dissociative adsorption increases resin utilization rate and the concentration of lysine in the permeate. this also reduces the consumption of water, analytical ammonia and wastewater discharge.

Tryptophan

01

APPLICATION

Ceramic membrane removes impurities and clarifies the permeate. This ensures high quality feed supplied to resin that ensures long lifespan of resin.
Continuous ion-exchange reduces chemicals and water consumption.
Nanofiltration removes impurities to improve the light permeability of tryptophan and lower the load of subsequent decoloring process.
