Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
205 words
A multiple unit fluid treatment apparatus having a cylindrical principal vessel extending through the apparatus and including first and second galleries both extending along the length of said vessel, external inlet means to said first gallery and external outlet means from said second gallery; a plurality of fluid treatment units each having a fluid treatment means enclosed in a generally cylindrical container detachably connected by fluidtight means to a head surrounding part of said principal vessel and rotatable about said vessel in a fluidtight engagement, and two ports in each said head respectively connecting the inlet and outlet sides of the said fluid treatment means; a plurality of sets of two further ports in the cylindrical surface of said principal vessel, one set for each said unit, one port of each set communicating with said first gallery and the other port of each set communicating with said second gallery, and said ports in each said head being capable of being brought into and out of registration with the respective ports of a cooperating set in said principal vessel by rotation of said fluid treatment unit about said vessel to connect and disconnect the fluid treatment means in said unit so rotated with said two galleries.
