Customised Integrated Solution

Organic Acid

Suntar, together with organic acid production companies, developed a series of membrane technologies combined with continuous moving bed technology for the production of organic acids based on years of membrane application and engineering experience.

  • Ceramic membrane clarifies fermentation broth, improves filtrate quality and reduces resin pollution in the subsequent processes.
  • Membrane filtration removes impurities with small MWCO and improves the product quality.
  • Continuous ion-exchange moving bed increases desalination stability and product recovery rate as well as reduce resin consumption.
  • Chromatography extracts organic acids and revolutionized the extraction process.

Lactic Acid

01

APPLICATION

Nanofiltration: Reduce reducing sugar concentration in the product which increase its thermal stability. Membrane filtrations produce high quality lactic acid.
Continuous moving bed ion-exchange process greatly increases resin utilization and reduce material consumption.

Citric Acid

The traditional citric acid extraction method calcium salt precipitation method which is hindered by the low filtration quality of traditional filtration processes which causes problems to the subsequent processes.

 

Suntar developed continuous ion-exchange technology for clean production of citric acid based on many years of membrane application and engineering experiences which revolutionized the citric acid production industry.

01

APPLICATION

Continuous ion-exchange with increased resin utility reduces material consumption and increases citric acid product concentration

Vitamin

Vitamin is an organic molecule that is an essential micronutrient that an organism needs in small quantities for the proper functioning of its metabolism.

Initially, Suntar worked together with many vitamin companies to apply both membrane separation technology and continuous moving bed technology into vitamin production which achieved significant results in multiple vitamins including, Vitamin C, Vitamin B2, Vitamin B12, etc. Suntar revolutionized the extraction process of Vitamin C by successfully developing a Vitamin C production process based on membrane separation and moving bed technology. This greatly reduced the production cost and turned China's Vitamin C from the yellow“ Cuban sugar” to“ white sugar” grade.

  • Clarify fermentation broth with membrane which improves filtrate quality and reduce resin pollution in subsequent processes
  • Apply ultrafiltration to remove protein, decolourise and improve quality
  • Concentrate vitamins with nanofiltration with reduced losses and lower cost
  • Adopt moving bed ion exchange to reduce resin consumption
  • Chromatography separates and recover vitamin solution
  • Membrane technology to recycle wastewater and reclaimed water

Vitamin C

01

APPLICATION

Suntar designs the safest and most suitable complete process for the production and extraction of vitamin C with internationally leading technology.
Membrane filtration of vitamin C fermentation broth with accurate MWCO achieving high quality filtrate and recovery > 98%.
Concentration of gulonic acid to over 16% with nanofiltration reduces steam consumption and greatly reduces operation costs.
Continuous ion-exchange moving bed system reduces the resin consumption by 70% for both sodium gulonate and sodium vitamin C conversion process. Greatly reduce water, acid and alkaline consumption to achieve clean production.

Vitamin B12

01

APPLICATION

Ceramic membrane removes impurities in fermentation broth, achieving high filtrate quality.
Ultrafiltration membrane further removes smaller proteins, improving subsequent resin performance.
Concentrate Vitamin B12 with membrane, improving subsequent resin adsorption rate.
Continuous ion-exchange reduces resin consumption, significantly reduces water and chemical consumption achieving clean production.
