A fill pack includes a first fill sheet defining an air intake edge, an air exit edge and an airflow axis extending between the air intake edge and the air exit edge. The first fill sheet defines a first flute section having a first inlet end, a first outlet end and a first peak extending between the first inlet end and the first outlet end. A second fill sheet defines a second flute section having a second inlet end, a second outlet end and a second peak extending between the second inlet end and the second outlet end. The first peak extends relative to the second peak such that a first flute portion defined by the first and second flute sections has a cross-sectional shape that changes between the first and second inlet ends and the first and second outlet ends.
摘要:
An apparatus for monitoring alignment of a transverse member conveyor wherein the member is attached transversely at opposite end portions to two parallel endless chains and includes two position sensors affixed and located transversely adjacent to each chain and each other. One or more targets are attached to link of each chain, and at predetermined distances from the member. The position sensors inductively or magnetically sense the relative position of the target on each chain with respect to the respective position sensor adjacent the chain, and send a signal comparing the target and sensor proximity with respect to the target on each chain. This allows determination of whether the opposite end portions of the member attached to the respective chains are aligned transversely within predetermined tolerance limits. Another aspect is monitoring a single position on an endless chain. Another aspect monitors chain catenary.

A wastewater or sludge treatment fixed film cross-flow distribution media corrugated sheet (84, 84′, 84″) and assemblies (118, 118′, 118″) thereof include corrugations (98, 98′, 98″), angled of about 10° to about 80° to the top and the bottom of the sheet and the assemblies. The sheet has a unitarily formed baffle (100, 100′, 100″) along at least a top portion of an exposed side of the sheet (96, 96′, 96″) or assemblies (130, 130′, 130″) exposed to denser wastewater or sludge outside of the assemblies than within the assemblies that is sufficient, when joined with either a like baffle (100, 100′, 100″) on a like sheet (84, 84′, 84″) or optional substantially planar interstitial sheets (132, 132′, 132″) adjacent the corrugated sheets, to substantially block air used in a sparging system from exiting or the denser wastewater or sludge being treated from entering the exposed side (96, 96′, 96″) of the sheet or the exposed side (130, 130′, 130″) of the assemblies. Beneficial biomass forming biofilm on the surfaces within the assemblies is controlled, effectively treating the wastewater or sludge.
摘要:
The invention relates to an aerobic wastewater digestion unit useful for degrading organic material dissolved or suspended in a wastewater stream. The wastewater is fed to a vessel, wherein it is circulated by a liquid conveyor between the vessel and a downwardly-directed tube. Expulsion of fluid from the tube into the lower portion of the vessel agitates the liquid in the vessel and disperses into the liquid air that has been entrained in the liquid in the tube. The digester can be operated using varying liquid levels, and is amenable to batch, semi-batch, and continuous operation. The digester is suitable for use in combination with other components of wastewater treatment systems, and can be included as a module in modular wastewater treatment systems.

A fill sheet for cooling heat transfer fluid in a cooling tower includes an air intake end, an air outlet end, a top edge and a bottom edge. The air outlet end is positioned opposite the air intake end along a lateral axis. The top edge connects the air intake end and the air outlet end and the bottom edge also connects the air intake end and the air outlet end. The bottom edge is positioned opposite the top edge along a vertical axis. A plurality of flutes extends generally parallel to the lateral axis between the air intake end and the air outlet end. An offset extends generally parallel to the vertical axis. A first flute of the plurality of flutes transitions from a first peak at a first side of the offset to a first valley at a second side of the offset.
