Abstract: A clarifier can comprise a floor, inner and outer walls that each extends upwardly from the floor such that a tank is at least partially defined by the inner wall and a launder channel is at least partially defined between the inner and outer walls and is disposed along at least a majority of a periphery of the tank. A launder cover comprising one or more flexible sheets can be disposed over at least a majority of the launder channel. Each of the sheet(s) can have opposing inner and outer edges, the inner edge coupled to the inner wall and the outer edge coupled to the outer wall, and can be configured such that, when a single one of the inner and outer edges is decoupled from the inner and outer walls, the sheet is deformable to at least partially uncover the launder channel.

Abstract: A treatment system is disclosed and includes a storage basin for retaining liquid, a cover system that covers the storage basin, and media disposed within liquid retained in the storage basin. In an embodiment, the media may be attached to the cover system. In an additional or alternative embodiment, the media may be detached from the cover system. In some embodiments of treatment systems having detached media, one or more stands may be provided for supporting the media. Configuring the treatment system to include both the cover system and the media may improve the operational efficiency of the storage basin, and may increase the volume or amount of liquid that may be treated by the treatment system.

Abstract: This disclosure includes sludge covers, sludge management systems, and related methods. Some sludge covers use or include a mesh layer configured to be disposed over sludge and/or a supportive layer configured to be disposed over sludge and, if present, the mesh layer, and a substantially fluid-impermeable layer configured to be disposed over the mesh layer, if present, and the supportive layer, if present.
