Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid treatment systems face challenges in treating large volumes of fluid efficiently, requiring a large footprint, high hydraulic pressure loss, and prone to radiation source oscillation and breakage, while also being costly and difficult to maintain.
Innovation Solution
A fluid treatment system with radiation source assemblies arranged in a non-parallel orientation to the fluid flow, forming a staggered or V-shaped configuration, which reduces oscillation and allows for efficient disinfection with a smaller footprint and lower pressure loss, enabling the use of low-pressure high-output lamps and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If radiation source assemblies are arranged in parallel to fluid flow, then the system can treat large volumes of fluid, but the system requires a large footprint and experiences high hydraulic pressure loss
Solution Approach 1:
The radiation source assemblies are arranged at angles non-parallel to the fluid flow direction, transitioning from a conventional parallel arrangement to an angular configuration. This dimensional change in orientation allows the system to treat large fluid volumes while reducing the reactor footprint by utilizing three-dimensional space more efficiently.
2Productivity
If radiation source assemblies are arranged in parallel to fluid flow, then the system can treat large volumes of fluid, but the system experiences high hydraulic pressure loss
Solution Approach 1:
By arranging radiation source assemblies at angles non-parallel to the fluid flow, the system reduces hydraulic resistance and pressure loss while maintaining large fluid treatment capacity. The angular configuration optimizes fluid flow paths and reduces energy dissipation.
3Device complexity
If radiation source assemblies are arranged parallel to fluid flow, then the system structure is simple, but the radiation sources are prone to oscillation and breakage
Solution Approach 1:
The radiation source assemblies are arranged at asymmetric angles non-parallel to the fluid flow direction rather than in a symmetric parallel arrangement. This asymmetric angular configuration reduces oscillation forces on the radiation sources, improving their reliability and reducing breakage while maintaining structural feasibility.
4Reliability
If conventional enclosed chamber design is used, then the system provides complete containment, but accessibility to submerged equipment is difficult
Solution Approach 1:
The system divides the radiation treatment function into modular radiation source assemblies that can be independently accessed and maintained. The angular arrangement and modular design allow submerged equipment to be more easily accessed for cleaning and replacement while maintaining effective fluid containment during operation.

AI summary
The present invention relates to a fluid treatment system comprising: an inlet; an outlet; and a fluid treatment zone disposed between the inlet and the outlet. The fluid treatment zone has disposed therein: (i) an elongate first radiation source assembly having a first longitudinal axis, and (ii) an elongate second radiation source assembly having a second longitudinal axis. The first longitudinal axis and the second longitudinal axis are non-parallel to each other and to a direction of fluid flow through the fluid treatment zone. The present fluid treatment system has a number of advantages including: it can treat large volumes of fluid (e.g., wastewater, drinking water or the like); it requires a relatively small “footprint”; it results in a relatively lower coefficient of drag resulting in an improved hydraulic pressure loss/gradient over the length of the fluid treatment system; and it results in relatively lower (or no) forced oscillation of the radiation sources thereby obviating or mitigating of breakage of the radiation source and/or protective sleeve (if present). Other advantages are discussed in the specification.
