Large bubble mixer and method of using same in a wastewater treatment system
A mixer configured for releasing large bubbles into wastewater is provided. The mixer can include a central draft tube, an upwardly-extending member surrounding the draft tube, and an accumulator surrounding both the upwardly-extending member and the draft tube. A lower end of the draft tube sidewall may be sealed and not include any openings beneath the lower end of the upwardly-extending member, so as to prevent liquid pumpage through the draft tube. A method for treating wastewater in a system that includes at least one large bubble mixer and at least one fine bubble diffuser is also provided. The large bubble mixer and fine bubble diffuser may be supplied gas independently from one another. The method can include multiple modes of operation wherein gas is either supplied to the mixer, to the diffuser, to neither the mixer or the diffuser, or to both the mixer or the diffuser.
B01F 3/04 - Mélange, p.ex. dispersion, émulsion, selon les phases à mélanger de gaz ou de vapeurs avec des liquides
B01F 23/231 - Mélange de gaz avec des liquides en introduisant des gaz dans des milieux liquides, p. ex. pour produire des liquides aérés par barbotage
C02F 3/20 - Procédés par les boues activées utilisant des diffuseurs
A system and method for aerating and mixing wastewater that includes fine bubble diffusers located at least partially below a large bubble mixer. At least a portion of the gas discharged from the fine bubble diffusers is captured by the large bubble mixer and is reused by the large bubble mixer to form and release intermittent large bubbles. Prior to being captured by the large bubble mixer, the gas discharged by the fine bubble diffusers can aerate the wastewater. The large bubble mixer includes an accumulator that, upon becoming filled with gas, generates and releases a large bubble. Upon discharge from the large bubble mixer, the large bubbles generated therein may separate into a plurality of coarse bubbles for providing additional oxygen transfer and mixing of the wastewater. The system may include supply lines for supplying gas only to the fine bubble diffuser.

A diffuser membrane and a method for manufacturing the same are provided. In the method for manufacturing, a first material is heated and extruded to form a base layer and a second material is heated and extruded to form a coating layer. The base layer and coating layer may be extruded substantially simultaneously in a coextrusion process. Accordingly, the coating may be applied to the base layer in a manner that optimizes the bonding between the two layers and provides the ability to control the thickness of the coating layer. Alternatively, the base layer is formed initially and the coating layer is subsequently formed thereover. The first and second materials have differing properties. The first material may comprise polyurethane and the second material may comprise polyurethane and PTFE.

A wastewater treatment system is provided having a reactor, first and second bio media and an aeration system. The first bio medium is located proximate an inlet end of the reactor and extends vertically between a top water level and the reactor's floor. The second bio medium is located proximate an outlet end of the reactor and extends vertically between a bottom water level and the reactor's floor. The media are adapted for retaining solids within the reactor as clarified water is withdrawn after treatment. The first bio media is further adapted to act as a baffle thereby causing wastewater to flow generally uniformly into a primary reactor zone. The aeration system includes a plurality of diffusers, some of which may be located adjacent or underneath the bio media and are adapted for promoting the shaking the bio media when activated in order dislodge excessive biomass therefrom.

Submerged media useful with or without aeration and/or mixing to enhance an aquatic environment by promoting and retaining biogrowth. The media takes the form of a cluster of individual flexible elements having free ends. The media are submerged in a liquid such as a water or wastewater treatment basin or an aquaculture environment. The media are characterized by the ability to promote and retain microbial growth. The media clusters have substantial flow through thicknesses to provide a three dimensional effect along with baffling for increased contact with the liquid being treated. The media may be thin strips constructed to avoid sticking together to allow maximum exposed surface area. The media clusters can create oxic, anoxic and anaerobic environments for maximum treatment during flow through the media cluster. The flexibility of the media elements and their free ends automatically dislodges excessive biomass buildup to avoid clogging of the media.
