Modular MBR Frame for Wastewater Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional membrane bioreactor (MBR) systems require heavy, expensive stainless steel frames that are immovable and costly, making them impractical for modular and movable wastewater treatment applications, especially when used with HDPE liners, as they cannot be securely anchored without damaging the liner.
Innovation Solution
The use of modular, dynamically configurable wastewater treatment containers with lightweight corrosion-resistant MBR frames and liners made from materials like PVC, HDPE, and fiberglass, allowing for easy movement and secure installation without damaging the liner, and enabling incremental expansion and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavy stainless steel frames are used for MBR systems, then structural strength and stability are improved, but cost and immobility increase
Solution Approach 1:
The MBR system is divided into modular components (membrane modules, frames, tanks) that can be independently assembled and disassembled. This segmentation allows the system to maintain structural integrity when assembled while enabling easy relocation by separating into transportable modules.
Solution Approach 2:
The system transitions from a fixed static design to a dynamic reconfigurable design. Frames and membrane modules can be assembled, disassembled, and reconfigured based on operational needs, allowing the system to adapt its structure while maintaining required strength during operation.
2Strength
If heavy stainless steel frames are used for MBR systems, then structural strength is improved, but cost increases
Solution Approach 1:
The patent employs lighter, less expensive materials for frames and structural components that can be replaced or upgraded as needed. This approach replaces expensive stainless steel with more cost-effective materials while maintaining sufficient structural strength for the application.
Solution Approach 2:
The system uses composite construction combining different materials (such as aluminum frames with plastic components, or steel reinforcement with concrete bases) to achieve required structural strength at lower cost than solid stainless steel construction.
3Stability of the object's composition
If MBR frames are made immovable and sturdy, then stability is improved, but ease of operation and relocation decrease
Solution Approach 1:
The system is divided into modular sections that can be independently handled during relocation. This segmentation allows the stable assembled configuration during operation while enabling easy disassembly and relocation by moving individual modules.
Solution Approach 2:
The patent introduces intermediary elements such as removable fasteners, connection couplings, and mounting hardware that facilitate both stable assembly during operation and easy disassembly for relocation. These intermediaries enable the transition between stable and mobile states.

AI summary
Embodiments described methods, systems and apparatuses to utilize a plurality of membrane cartridges and a housing frame comprising a lightweight corrosion resistant material (e.g., non-corrosive metals, non-corrosive composites such as PVC, HDPE and FRP). The anti-corrosive properties of said frame allow of it to be re-used (e.g., with replaced MBR filters). Said MBR frame may be used in a single function or multi-function wastewater treatment container. Said container may also include a corrosion resistant liner coupled to interior portions of each of the base and side walls of the basin, an inlet to receive wastewater treatment influent into the basin, and an outlet to output wastewater treatment process material from the basin.
