Estimating the term…
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.
A filter for treating fluids comprising a matrix containing one or a plurality of types of particles, said particles having an inherently active surface having the characteristic of fluid treating capability to treat a fluid which comes into contact with said active surface, said particles being pervious to the flow of fluid, a moderately viscous binder, said binder being impervious to the flow of the fluid, said binder contacting said particles to secure said particles in place and create a densely packed bed, portions of said active surfaces of said particles being free of contact with said binder, and tortuous paths of flow being created through said bed at said portions of said active surface to cause a fluid to intimately contact said fluid treating material as the fluid flows through said bed.
