Abstract
Biomass support members, including woven textile media, useful in biological contact processes and apparatus; biomass support panels of limited flexibility and substantial surface expanse, with or without frames, comprising a variety of different woven or non-woven biomass supporting members, which may or may not include the foregoing media; biological treatment processes using biomass supporting panels in any at least partly supported growth biological process, whether a wastewater treatment or not; and biological wastewater treatment apparatus comprising diffusers and biomass support panels that may or may not include the above media, and which may also include certain preferred spatial and operational relationships.
Claims19
Biomass support member comprising:
- an elongated flexible mass of threads in the form of open-structure, bunched biomass-supporting elongated yarns that comprises gathered curly filaments in the yarns, and run generally in a common direction, along-side one another in the mass, and with overlapping of adjacent yarns of the mass, which mass of yarns has an expanse of length and width that are each at least 15 times their general thickness, and is “hydraulically open” in that water can flow from one face of the member, when laden with biomass, to biomass in the interior of the member, wherein the mass has a plurality of cross-supports, extending across the yarns at two or more intervals of yarn length, and comprises support member filaments that are of multi-lobed cross-section.
Biological treatment process which comprises, in at least a portion of the process, using support member panels comprising
- an elongated flexible mass of threads in the form of open-structure, bunched biomass-supporting elongated yarns that comprises gathered curly filaments in the yarns, and run generally in a common direction, along-side one another in the mass, and with overlapping of adjacent yarns of the mass, which mass of yarns has an expanse of length and width that are each at least 15 times their general thickness, and is “hydraulically open” in that water can flow from one face of the member, when laden with biomass, to biomass in the interior of the member, wherein the mass has a plurality of cross-supports, extending across the yarns at two or more intervals of yarn length, and comprises support member filaments that are of multi-lobed cross-section to support biomass.
