Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water treatment methods and apparatuses face challenges in efficiently and stably generating micro/nano bubbles, which are essential for enhancing treatment efficiency and improving water quality.
Innovation Solution
A water treatment method and apparatus that involves introducing treatment water to a first bubble treatment tank with a micro/nano bubble generator, then to a second tank for confirmation and control of bubble generation, optimizing the operation of both generators based on detected bubble states, and using turbidity meters to interlock air flow control valves for maintaining proper bubble generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If micro/nano bubble generators are used to enhance treatment efficiency, then water quality improvement is achieved, but stable and efficient bubble generation is difficult to maintain
Solution Approach 1:
The patent implements a feedback control system where a turbidity meter detects the generation state of micro/nano bubbles in the second tank and sends signals to the controller. The controller adjusts the operation of both bubble generators based on this feedback, maintaining stable and efficient bubble generation throughout the treatment process.
Solution Approach 2:
The patent divides the bubble treatment process into two separate tanks: a first bubble treatment tank for primary treatment and a second bubble treatment tank for confirmation and control. This segmentation allows independent optimization of each stage, improving overall reliability while maintaining high treatment efficiency.
2Productivity
If multiple bubble treatment tanks are used to optimize bubble generation, then treatment efficiency improves, but device complexity increases
Solution Approach 1:
The second bubble treatment tank serves multiple functions: it acts as a confirmation tank for bubble generation state, a control tank for optimizing bubble parameters, and a mixing tank for ensuring uniform distribution. This multi-functionality reduces the need for additional separate components, managing complexity while improving efficiency.
Solution Approach 2:
The patent combines the bubble generation, confirmation, and control functions into an integrated system where the second tank houses both a bubble generator and a turbidity meter, with the controller coordinating all operations. This merging of functions streamlines the apparatus structure despite having multiple tanks.

Data Source
AI summary
A water treatment apparatus has a turbidity meter, which is a detection part, for detecting a generation state of bubbles in a micro/nano bubble generation state confirmation tank, as a turbidity of treatment water. The water treatment apparatus also has a controller, which is a control part, for receiving an signal representing the turbidity of treatment water detected by the turbidity meter, to control openings of air flow control valves in an interlocked manner in response to the signal, so that the amount of air flowing through the control valves is automatically controlled. The openings of the air flow control valves are controlled in an interlocked manner by the controller in such a way that the signal representing turbidity shows that the treatment water within the confirmation tank is whitely turbid (i.e., the turbidity shows not less than a specified value).
