Pulverulent or very fine-grained, physically/chemically active substances are applied to a support material, which determines the filter structure, by the precoat process at high flow velocity and distributed as uniformly as possible on its surface and are made to adhere reversibly to this surface. By reversing the directions of flow, the active substances can be completely removed. Such filter units can be connected in series one after the other and can be furnished with a shared connectable and disconnectable conditioning circulation having a circulation pump designed for high flow velocity and high output rate. |
