A novel sealing and supporting means for treating trays in fluid-treating apparatus in which the fluid-treating apparatus is comprised of a vessel having ledges on inner walls thereof forming liquid-containing chambers and treating tray structure resting on the ledges and supported thereby. The tray structure has flanges depending into the chambers for forming a liquid seal therewith whereby the ascending fluids are prevented from escaping around the peripheries of the trays. The provision of liquid seals at the peripheries of the trays avoids welding or bolt and gasket seals, facilitating the installation and removal of the trays and reducing construction and maintenance costs.
