Abstract
A column for removing poisons and/or other undesired substances from a liquid mixture. The column has a mixture of inactive filler particles and active granules positioned therein, with said filler particles being substantially larger than said active granules, (which are selected from adsorbing material and ion-exchanging material). The filler particles are in fixed contact relationship with each other and the active granules completely fill the spaces between the filler particles.
