Nonwoven fibrous webs including amorphous polymeric fibers with improved and/or more convenient bondability are disclosed. The nonwoven fibrous webs may include only amorphous polymeric fibers or they may include additional components in addition to amorphous polymeric fibers. The amorphous polymeric fibers within the web may be autogeneously bonded or autogeneously bondable. The amorphous polymeric fibers may be characterized as varying in morphology over the length of continuous fibers so as to provide longitudinal segments that differ from one another in softening characteristics during a selected bonding operation.

Nonwoven amorphous fibrous webs and methods for making them

An assembly and method for cleaning a conveyor belt system is disclosed. The cleaning assembly is for removing liquids and solids from an endless conveyor belt, the assembly includes a plurality of laterally extending liquid absorbent material sheets disposed adjacent the belt, with the sheets collectively defining a contact face that is engageable with the belt for wiping liquids from the belt.

Conveyor belt cleaning system

Described is an apparatus for the removal of organic substances and/or nitrogen sources from an aqueous medium by exposing the aqueous medium to the action of microorganisms supported on a gas permeable, water impermeable layer, or on and/or in a three dimensional microbial support layer, that is proximate a gas delivery layer through which gas, preferably, oxygen-containing gas, is supplied to the gas permeable layer such that it diffuses through the gas permeable layer and is supplied to the microorganisms.

Layered sheet construction for wastewater treatment

An assembly for cleaning a conveyor belt system is disclosed. The cleaning assembly is for a conveyor belt system with the type having first and second endless belts which each traverse a separate belt travel path and together define a generally upright article transport path between opposed top faces of the belts. The cleaning assembly includes a belt wiping blade assembly for moving liquids and debris from a belt, an absorbent material downstream from the blade assembly for wiping excess liquid from the belt, and belt edge seals disposed between the opposed top faces of the belts along the article transport path.
