Abstract: An apparatus is presented that includes a body and a membrane. The body defines an externally hemispherical body portion with an orifice, as well as a channel passing through the body and terminating in the orifice. The membrane is formed at least in part of an elastomeric material and overlies a portion of the externally hemispherical body portion. The membrane defines a plurality of holes therein, and a plug that is inserted into the orifice and the channel. When submerged at the bottom of a wastewater treatment tank and in gaseous communication with a distribution conduit providing compressed gas, the apparatus may function to release bubbles into the wastewater. When the compressed gas is turned off, the apparatus acts as a check valve that stops water from entering the diffuser and the distribution conduit.

Abstract: A wastewater filter cartridge includes a peripheral frame, two filter media sheets, two sets of angled fins, and a filtered water outlet. The two filter media sheets are attached to the peripheral frame in spaced face-to-face relation such that they combine with the peripheral frame to define an interior volume within the filter cartridge. At the same time, the two sets of angled fins are attached to the peripheral frame external to the interior volume and project away from the filter media sheets at oblique angles. As wastewater passes through the two filter media sheets into the interior of the filter cartridge, the two filter media sheets act to reduce the suspended solids in the wastewater. Once in the interior volume of the filter cartridge, the filtered water is collected via the filtered water outlet, which is connected to the interior volume.

Abstract: Aspects of the invention describe a tube diffuser design and associated saddle design that allow the two elements to be easily and quickly attached to each other in the field for the purpose of aerating wastewater. The tube diffuser is cylindrical and includes a gas distribution section spanning across an interior diameter of the tube diffuser. The saddle includes a pair of engagement arms that are able to couple to this gas distribution section of the tube diffuser. Once the tube diffuser is attached to the saddle and the assembly is submerged in wastewater, the saddle may be used to transport air from an air distribution pipe to the tube diffuser. The air may then be made to leave the tube diffuser as a plume of air bubbles.

Abstract: A diffuser assembly includes a flexible diffuser membrane and a diffuser body. The flexible diffuser membrane defines a perimeter edge bead along four edges. The diffuser body defines an underlying body portion underlying the flexible diffuser membrane, and a perimeter edge frame covering a covered portion of the perimeter edge bead. The edge frame defines an inside surface that conforms to an outside shape of the covered portion of the perimeter edge bead. The perimeter edge frame is integral to the underlying body portion.

Abstract: A diffuser assembly includes a flexible diffuser membrane and a diffuser body. The flexible diffuser membrane defines a circumferential bead. The diffuser body defines a circular plate underlying the flexible diffuser membrane, and an edge ring covering a covered portion of the circumferential bead. The edge ring defines an inside surface that conforms to an outside shape of the covered portion of the circumferential bead. The edge ring is integral to the diffuser body. Such a diffuser assembly may provide a disposable diffuser assembly option with many advantages over conventional technologies such as improved ease of installation, lower weight, and lower cost.

Abstract: An apparatus for use with a wastewater treatment tank is described. The apparatus includes a track, pipe modules coupled to the track such that the pipe modules are translatable along the track, and diffusers attached to the pipe modules. Each pipe module defines a respective partially curved mating surface, a respective partially curved mating cavity, and a respective gas passage passing through it. The respective partially curved mating surface of a first pipe module is inserted into the respective partially curved mating cavity of a second pipe module, while the respective partially curved mating surface of the second pipe module is inserted into the respective partially curved mating cavity of a third pipe module. Each gas passage of the pipe modules is in gaseous communication with the other gas passages of the pipe modules. At the same time, each diffuser is in gaseous communication with the gas passages of the pipe modules.

Abstract: An apparatus comprises a distribution conduit, a diffuser body, and an insert. The distribution conduit defines an aperture. The diffuser body defines a mating tube, at least a portion of the mating tube passing through the aperture, and the mating tube defining a mating tube passage therethrough with an inside sidewall. The insert is at least partially disposed in the mating tube passage and presses against the inside sidewall so as to cause the mating tube to expand. Removal of the mating tube from the distribution conduit is thereby inhibited.

Abstract: A process for forming a biofilm carrier suitable for use in a moving bed biofilm reactor (MBBR) is presented. A blowing agent is mixed with a plastic material to form a blended material. The blended material is then heated to a temperature where the blowing agent liberates gas by decomposition. The heated blended material is extruded through a die to provide the extrudate with a profile of the biofilm carrier. Advantageously, biofilm carriers produced in this manner have increased effectiveness when compared to conventional biofilm carriers.
