Suntar Membrane System

High Pressure RO Membrane

Reverse osmosis is a water treatment process that removes contaminants from water by applying pressure to force water molecules against the concentration gradient through a semipermeable membrane. It is widely used in the purification and concentration of various liquids. The most common application of reverse osmosis is water purification which removes impurities such as inorganic ions, bacteria, viruses, organic compounds and colloids to obtain high-quality purified water.

Ultra-high-pressure reverse osmosis can be utilized to further remove any water in the concentrate after the reverse osmosis and/or the high-pressure reverse osmosis process. The membrane's highest operating pressure is 120Bar at a maximum temperature of 30℃ and has the characteristics of a high salt rejection rate.

Plant Extraction

In recent years, membrane separation technology in plant extraction has become more abundant. Suntar has also developed many applications in the plant extraction industry and an overall production process based on membrane separation technology and moving bed technology.

  • Apply ceramic membrane for the extraction of clarified liquid achieving higher filtrate quality, reduces resin pollution and solvent consumption in the subsequent processes.
  • Ultrafiltration removes protein, pigment and improves quality.
  • Nanofiltration concentrates plant extract which improves crystal recovery and reduces evaporative loss.
  • Continuous ion-exchange moving bed system replaces fixed bed system which reduces resin consumption and unit consumption.
  • Membrane technology to recycle wastewater and reclaimed water.

Aloe Vera Juice

01

APPLICATION

Ceramic membranes remove impurities and clarify extract which improves filtrate quality and recovery.
Nanofiltration concentration increases aloe vera juice soluble solid concentration from 0.75% over 7%

Stevia

01

APPLICATION

Membrane filtration has ideal impurity removal and clarification effect on stevia extract, and can better remove suspended solids, and pigments as well as improve product quality and yield.
Nanofiltration membrane increases the efficiency of resin adsorption and significantly reduces wastewater discharge. The filtrate can be discharged directly or be treated further and recycled.
Continuous moving bed reduces resin consumption by over 60% as well as reduces regenerant consumption and wastewater discharge by over 50%.
Wastewater treatment in each process becomes simpler with membrane. Membrane filtrate and the lower column waste of the resin adsorption process are fully recovered through reverse osmosis to achieve zero discharge.

Inulin

01

APPLICATION

Continuous moving bed separates the extract, reduces the resin consumption by 60%, saves more than 50% of the regenerant, and reduces wastewater discharge by more than 60%.
Nanofiltration concentrates the product to meet the needs of the subsequent processes, improves recovery rate and reduces energy consumption.
