Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If powder catalytic materials are used in advanced oxidation processes, then catalytic activity is improved, but separation from treated water becomes difficult and secondary pollution occurs
Solution Approach 1:
The patent employs porous ferrite particles as the catalytic material. The porous structure provides high surface area for catalytic reactions while the particulate form enables easy separation from treated water through sedimentation or filtration, eliminating the harm of powder suspension and secondary pollution.
Solution Approach 2:
The patent uses composite ferrite materials with specific compositions (e.g., Fe3O4, Fe2SiO4, FeAl2O4) that combine catalytic activity with separable physical properties. These composite particulate materials maintain high catalytic performance while allowing complete separation from water, preventing secondary pollution.
2Ease of operation
If powders are attached on porous carriers to improve separability, then separation becomes easier, but powders may falloff during degradation process
Solution Approach 1:
The patent extracts the catalytic function from powder form and concentrates it into stable particulate ferrite materials. By using inherently stable ferrite particles rather than attaching powders to carriers, the solution eliminates powder falloff while maintaining separability and catalytic activity.
Solution Approach 2:
The patent employs robust ferrite particles that can be easily separated and reused multiple times without degradation. The materials are designed for repeated use in AOP processes, maintaining stability and avoiding the need for frequent replacement.
3Productivity
If powders are used to enhance catalytic effect, then organic degradation efficiency is improved, but loss of powders reduces reuse potential
Solution Approach 1:
The porous ferrite particles provide high surface area for catalytic reactions, enhancing organic degradation efficiency. The particulate form allows complete recovery through sedimentation or filtration, enabling reuse without material loss and maintaining high productivity across multiple cycles.
Solution Approach 2:
The patent facilitates easy recovery of catalytic material through sedimentation or filtration of the particulate ferrite. The recovered particles can be reused in subsequent AOP treatments, preventing loss of substance and maintaining continuous high productivity.
