Title: Filter for adsorption from and/or dispersion of ingredients into a fluid

Abstract: A filter for the adsorption of ingredients from and/or the dispersion of ingredients into a fluid includes a matrix which has a plurality of particles having an inherently active surface or an active surface made of a fluid treating material. The particles are held in place by a moderately viscous binder which is impervious to the flow of the fluid. The particles, however, are made of a fluid pervious material. An insufficient amount of binder is incorporated in the matrix to otherwise completely cover the particles. Thus portions of the active surface of the particles remains exposed to the flow of fluid thereby resulting in tortuous paths of flow through the matrix, thereby assuring contact with the treating particles.
