摘要：
The invention relates to a method for concentrating an at least partially crystalline solid containing at least one zeolite in a mixture, said mixture containing at least one auxiliary agent, for example a template compound, and the cited solid. The inventive method is characterised in that the mixture is divided into a retentate and a permeate in one step (II) by means of ultrafiltration, the solid content in the retentate being higher than that in the mixture and the solid content in the permeate being lower than that in the mixture. Said method enables auxiliary agents in the permeate, especially template compounds, to be redirected into a crystallisation step (I) which precedes the cited step (II).
