Definitions
- the invention relates to formulations consisting of cellulose, alkali caseinate and crosslinked homopolymers or copolymers of Isf-vinyl lactams and / or polymers based on a basic N-vinyl heterocycle with a pK a value of at least 3.8, the production and use thereof for the treatment of biological liquids of vegetable origin in a non-fermented, partially fermented or fully fermented state.
- the disadvantage with the native and modified proteins and the crosslinked polymers is that they require a certain pretreatment by swelling. This means a very large amount of time. Since the vast majority of products medium is extracted together with the suspended turbidity by sedimentation, this step is also very time-consuming and can take up to 6 weeks. In addition, these products have the disadvantage that they do not remove all phenolic substances or classes of substances to the same extent, but that there is in each case a preferred interaction with a certain group of phenolic substances.
- the anfal ⁇ lumbar sediments are mostly schleimigpast Surprise masses, which is removed by a downstream treatment liquid in order to bring them into a results processed further or landfillable state.
- the invention was therefore based on the object of finding a product which does not have the disadvantages mentioned above and is able to reduce the content of different groups of phenolic compounds and at the same time also the concentration of dissolved heavy metals. At the same time, manageability should be improved by eliminating the complex preparation phase of the feed material.
