Solution Overview
Problem
Existing UV radiator modules for water or wastewater treatment require complex sensor arrangements for monitoring individual UV sources, leading to increased complexity and effort in installation and operation.
Innovation Solution
A UV radiator module design featuring two rows of UV radiators with a single UV sensor positioned between them, allowing for simplified monitoring and control, with the sensor being tubular and equipped with a mirror element for 360° sensitivity, and connected to a common control unit for flexible operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate sensor is assigned to each UV radiator for monitoring, then the radiation output of each radiator can be monitored individually, but the complexity of the sensor arrangement and its evaluation increases
Solution Approach 1:
Multiple separate sensors assigned to each UV radiator are merged into a single sensor that monitors the entire array of UV radiators collectively. This reduces the number of sensors from N (one per radiator) to 1, thereby reducing sensor arrangement complexity and evaluation burden while maintaining adequate monitoring capability through the combined signal from all radiators.
2Reliability
If multiple UV radiators are arranged in parallel rows, then the UV radiation coverage is improved, but the accessibility of individual UV radiators for maintenance deteriorates
Solution Approach 1:
The array of UV radiators is segmented into two distinct parallel rows, which allows the system to maintain good UV radiation coverage across the water channel while improving maintenance accessibility. The segmentation creates clear access pathways between and around the rows, enabling technicians to reach individual radiators more easily for maintenance while still providing comprehensive coverage through the combined output of both rows.

AI summary
A UV radiator module includes a number of elongated UV radiators arranged with their longitudinal axes parallel to one another in the UV radiator module. The UV radiators are arranged in two parallel rows which are spaced apart from one another. A UV sensor is set up to detect UV radiation emitted by the UV radiators. The UV sensor is arranged between the two rows.
