Chromatography is a groundbreaking technology used to separate the components in a mixtures using only water.
Chromatography is a groundbreaking technique used to separate the various components in a mixture. There are two different phases; the mobile phase moves through a bed constituting the fixed or stationary phase. During elution, which is performed with water, the solute with greatest affinity to the stationary phase is delayed, while the one with least affinity moves at high speed.
The RWL Water developed technology is based on the ISMB (Improved Simulated Moving Bed) chromatographic system which, in addition to guaranteeing continuity of the process, limits water consumption. It does not use chemical agents and reduces the saline content of the starting material by over 90%.
The main advantage of this technique is the absence of chemical reagents such as acid and soda. These particular resins used are never regenerated; the saline and polluting load in the wastewater is also greatly reduced.
RWL Water has been investing in this technology for several years in order to apply it, on a small scale, to the demineralization of food liquids such as grape must, apple juice, whey. It is also being applied to the separation of various compounds, such as glucose and fructose from RCM (rectified concentrated must) or fructose-glucose and sucrose from concentrated apple juice, contained in a mixture,
The latest international regulations (2013) have established ISMB technology as the only technique allowed for obtaining organic certification of fruit juices.
