    摘要： 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： A biofilm process is disclosed for treating wastewater containing readily biodegradable dissolved organic matter (measured as chemical oxygen demand or COD) and producing surplus biomass from the biofilm process that includes an enhanced polyhydroxyalkanoate (PHA) content. The process comprises directing a wastewater influent containing the readily biodegradable COD (RBCOD) into a biofilm unit process. The PHA content of surplus biomass is enhanced by controlling for a decreased biofilm process specific organic loading rate in combination with controlling phosphorus loading rates relative to the process RBCOD loading rates: (1) controlling the wastewater influent phosphorus loading rate to the biofilm unit process includes maintaining an average RBCOD/P ratio of the influent that is between 200 and 800 g/g; (2) decreasing the process specific organic loading rate includes producing a biofilm unit process effluent having readily separable mixed liquor volatile suspended solids (RS-MLVSS); and (3) separating a portion of the RS-MLVSS from the biofilm unit process effluent and recycling at least a portion of the separated RS-MLVSS back to the biofilm unit process. The combination of the RBCOD/P control and specific loading rate control maintains, on average, the surplus biomass with a PHA content that is greater than 30% gPHA/g VSS.

    摘要： The invention relates to an installation element (1) for use in cooling technology, in water treatment, or in mass transfer. The installation element (1) is self-supporting and is composed of a plurality of plies (10), which are at least partially spatially structured and which are connected to each other. Adjacent plies (10) form flow paths (14) for a liquid and/or for a gaseous medium between said adjacent plies. The installation element (1) according to the invention is characterized in that at least some of the plies (10) are composed of an at least three-layer coextruded plastic film, that a center layer (11) of the three-layer plastic film is a mechanically supporting plastic layer, and that the two outer layers (12, 13) of the three-layer plastic film either are composed of a plastic having application-specific properties or are plastic layers each having at least one additive, which is added to the plastic and which gives application-specific properties to the outer layers. The invention further relates to a method for producing such an installation element (1).
