Multi-Disc Diffuser Mount for Faster Wastewater Aeration Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for assemblies that allow large numbers of smaller-diameter disc diffusers to be economically and efficiently installed in wastewater treatment tanks, while being robust enough to withstand harsh operating conditions.
Innovation Solution
A diffuser assembly comprising a diffuser mount with a mount-to-pipe connection portion, distribution conduits, and curved mount-to-diffuser attachment slots, allowing for the snap-fit attachment of multiple disc diffusers, which are connected via a grommet to a pipe, facilitating efficient aeration without the need for specialized tools or fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If smaller-diameter disc diffusers are used, then aeration efficiency is improved and membrane deflection is reduced, but installation complexity and time increase due to the need to install larger numbers of diffusers
Solution Approach 1:
Multiple disc diffusers are merged into a single assembly unit by attaching them to a common distribution manifold. This allows numerous small-diameter diffusers (e.g., 6-10 diffusers per assembly) to be installed as one integrated unit rather than individually, significantly reducing installation time while maintaining the aeration efficiency benefits of smaller diffusers
Solution Approach 2:
The disc diffusers are pre-assembled and pre-configured on the distribution manifold before being deployed in the wastewater treatment tank. This preliminary assembly action prepares the complete diffuser assembly in advance, eliminating the need for on-site installation of individual diffusers and reducing overall installation time
2Manufacturing precision
If smaller-diameter disc diffusers are used, then air distribution uniformity is improved, but the number of diffusers required increases leading to higher assembly complexity
Solution Approach 1:
The air distribution system is segmented into multiple small-diameter diffusers (6-10 per assembly) rather than using fewer large diffusers. Each diffuser is a standardized modular component with uniform dimensions, and the distribution manifold is divided into multiple branches that feed each diffuser equally, ensuring uniform air distribution while organizing complexity into manageable segments
Solution Approach 2:
The distribution manifold serves multiple functions simultaneously: it acts as a structural support for the diffusers, provides uniform air distribution through multiple branches, and facilitates easy assembly and disassembly of the diffusers. This multi-functionality reduces overall system complexity despite the increased number of diffusers
3Area of stationary object
If larger numbers of disc diffusers are installed, then aeration coverage is improved, but installation cost and labor requirements increase
Solution Approach 1:
Multiple disc diffusers are combined into integrated assemblies with distribution manifolds, allowing large numbers of diffusers (providing extensive aeration coverage) to be installed as fewer complete units. This merging approach reduces the total number of separate installation operations required, lowering labor costs and installation expenses while maintaining comprehensive aeration coverage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the efficient installation of numerous smaller-diameter disc diffusers, providing uniform air distribution, reducing spiral flow and bubble coalescence, and enhancing aeration efficiency in wastewater treatment systems.
Implementation Method 1
a plurality of distribution conduits in gaseous communication with the mount-to-pipe connection portion
Implementation Method 2
When pressurized with air, the diffuser membrane of a smaller-diameter disc diffuser tends to deflect less than that in a larger-diameter disc diffuser, resulting in a more uniform distribution of air
Implementation Method 3
This causes the air to pass through the holes in the diffuser membrane into the water, forming a plume of small bubbles

AI summary
An exemplary wastewater treatment system includes a pipe, a diffuser mount, and four disc diffusers. The diffuser mount includes a mount-to-pipe connection portion attached to the pipe, four distribution conduits arranged in a cross shape and in gaseous communication with the mount-to-pipe connection portion, and four curved mount-to-diffuser attachment slots located above the four distribution conduits. Each of the four disc diffusers occupies one of the four curved mount-to-diffuser attachment slots and is attached to one of the four distribution conduits. Configured in this manner, each of the four disc diffusers is in gaseous communication with an interior of the pipe and can be used to generate plumes of bubbles in wastewater for aerobic wastewater treatment applications.
