ABSTRACT:
A tank containing a bed of particulate material, e.g. a sand filter bed or an ion exchange bed, has a bed-supporting bottom structure formed by upper and lower bottom plates rigidly connected with each other through a plurality of vertical sleeves opening into the spaces above and below the tank bottom structure. Openings in the wall of each sleeve connect the interior of the sleeve with the compartment formed between the bottom plates. A strainer unit is removably inserted in each sleeve through the lower end of the sleeve and passes liquid between the bed and the compartment between the bottom plates by way of the openings in the side wall of the sleeve. An adjustable valve member accessible from below the tank bottom structure serves to control the flow of liquid through the strainer unit.
