Lewatit® S 7968 is a food grade, macroporous adsorber resin without functional groups. It has beads of a uniform size (monodisperse). It can be used in the extraction/purification of: natural or synthetic organic products in the food industry. In addition, it can be used for the adsorption/removal of:- anionic, cationic, and nonionic surfactants
- chlorinated and nitrated hydrocarbons
- colorants of inert organic materials
- for removing of non-polar organic ingredients of low molecular mass from land fill leachates
- for debittering of fruit juices
Lewatit S 7968 has the following properties:- very good mechanical stability and low attrition
- longer resin life time and better regeneration efficiency compared to activated carbon
- high adsorption capacity especially at medium and high feed concentration
- good kinetic performance during adsorption and elution
Prior to industrial application, preliminary tests should be carried out on a laboratory scale, in order to determine the maximum adsorptive capacity and the optimum regenerant. Experience has shown that the maximum capacity of the adsorber resin is reached after the third cycle. When using Lewatit S 7968 to treat potable water and the aqueous solutions listed above, special care should be given to the initial cycles of the new resin.Information provided by Lanxess. |
