LIQUID TREATMENT APPARATUS

摘要

A liquid treatment apparatus suitable for dewatering a radioactive sludge includes a cylindrical housing (14) open at one end and defining two ports (24, 26) for the sludge, one near the open end and the other at the closed end. A plug (30) locates in the open end of the housing and supports a module (44) comprising a sealed permeate-collecting chamber (46) through which extend a number of permeable-walled tubes (54), open at each end. The plug defines a header chamber (40) for the tubes (54) which communicates with the one sludge port (24); and defines an outlet duct (62, 38) for the permeate liquid. The apparatus can be installed remotely within a shielded enclosure (12), and the plug and module can be withdrawn without risking contamination of the permeate liquid.
