Abstract
A liquid treating apparatus in which a vertically disposed tank has a series of longitudinally arrayed volume variable beds of liquid treatment material with fluid permeable partitions between the beds which move longitudinally in response to expansion and contraction of the beds. Forming a part of each partition and moving therewith is a fluid conduit system for collecting and distributing fluids between pairs of beds.
Claims33
A liquid treatment apparatus, comprising:
- a generally vertically disposed tank having a plurality of fluid permeable beds arranged in longitudinal sequence in said tank generally one above the other, each of said beds being composed of a liquid treatment material and at least one of said beds beneath the top most bed being volume variable;
- each said at least one volume variable bed having a fluid permeable partition situated above said bed separating said bed from the next bed, each said partition being freely longitudinally movable with respect to said tank and including partition conduit means for collecting and distributing fluids at said partition, each said partition conduit means being an integral part of its partition and being freely longitudinally movable therewith;
- each said partition having associated therewith a main fluid conduit passing between the inside and the outside of said tank to which said partition conduit means is connected;
- and,
- each said partition including sealing means about its periphery which engages the inside wall of said tank to prevent the passage of said liquid treatment material between said partition and said inside wall while permitting the relative movement of said partition with respect to said tank.

A liquid treatment apparatus, comprising:
- a generally vertically disposed tank having two fluid permeable beds therein arranged generally one above the other so as to define an upper bed and a lower bed, each of said beds being composed of a liquid treatment material with at least said lower bed being volume variable;
- a fluid permeable partition in said tank separating said beds, said partition supported by said lower bed and in turn supporting said upper bed, said partition being freely longitudinally movable with respect to said tank in response to expansion and contraction of said lower bed and including partition conduit means for collecting and distributing fluids between said beds, said partition conduit means being an integral part of said partition and being freely longitudinally movable therewith;
- a main partition fluid conduit passing between the inside and the outside of said tank to which said partition conduit means is connected;
- and,
- said partition including sealing means about its periphery which engages the inside wall of said tank to prevent the passage of said liquid treatment material between said partition and said inside wall while permitting the relative movement of said partition with respect to said tank.

A liquid treatment apparatus, comprising:
- a generally vertically disposed tank having two fluid permeable beds therein arranged generally one above the other so as to define an upper bed and a lower bed, each of said beds being composed of a liquid treatment material with at least said lower bed being volume variable;
- a plurality of fluid permeable partitions separating said beds, each of said partitions being a sector of a circle such that all of said partitions define a complete circle with each of said partitions being supported by a portion of the surface area of said lower bed and in turn supporting a portion of the surface of said upper bed;
- each of said partitions being freely longitudinally movable with respect to said tank in response to expansion and contraction of said lower bed;
- said partitions being separated from one another by walls coinciding with the radii of said tank extending transversely from the longitidinal axis of said tank to the wall thereof and extending longitudinally into said upper and lower beds past the limits of the longitudinal travel of said partitions;
- each of said partitions including a partition conduit means for collecting and distributing fluid between said beds and a main partition fluid conduit passing between the inside and the outside of said tank to which said partition conduit means is connected, each said partition conduit means being an integral part of its partition and being freely longitudinally movable therewith;
- and,
- each of said partitions also including sealing means about its periphery which engages the inside wall of said tank and said radial walls to prevent the passage of said liquid treatment material between said partition and said tank wall or said radial walls while permitting the relative movement of said partition with respect to said tank wall and said radial walls.

A liquid treatment apparatus, comprising:
- a generally vertically disposed tank having two fluid permeable beds therein arranged generally one above the other so as to define an upper bed and a lower bed, each of said beds being composed of a liquid treatment material with at least said lower bed being volume variable;
- an impermeable partition in said tank separating said beds, said partition supported by said lower bed and in turn supporting said upper bed, said partition being freely longitudinally movable with respect to said tank in response to expansion and contraction of said lower bed and including sealing means about its periphery which engages the inside wall of said tank to prevent the passage of said liquid treatment material between said partition and said inside wall while permitting the relative movement of said partition with respect to said tank;
- a first partition conduit means attached to and positioned immediately above said partition for collecting and distributing fluids immediately above said partition, said first partition conduit means being freely longitudinally movable with said partition;
- a second partition conduit means attached to and positioned immediately below said partition for collecting and distributing fluids immediately below said, said second partition conduit means being freely longitudinally movable with said partition;
- a first main partition fluid conduit passing between the inside and the outside of said tank to which said first partition conduit means is connected;
- and,
- a second main partition fluid conduit passing between the inside and the outside of said tank to which said second partition conduit means is connected.
