Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swimming pool water treatment systems require constant operator attention and are not reliable in detecting turbidity levels, leading to sub-optimal purification and excessive energy consumption, as they often overestimate or underestimate contamination levels, resulting in inefficient use of purification substances and mechanical filters.
Innovation Solution
A plant and method that automatically control filtration and purification cycles based on predefined turbidity thresholds, using multiple sensors and a control unit to adjust the recirculation pump's speed and chemical substance dispensation according to real-time water quality parameters, optimizing energy consumption and filtration efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If constant purification cycles are operated to maintain water quality, then water cleanliness is improved, but energy consumption increases
Solution Approach 1:
The system uses turbidity sensors to continuously monitor water quality and provides feedback to the control unit, which automatically adjusts or activates purification cycles based on actual contamination levels rather than operating on fixed schedules, thereby reducing unnecessary energy consumption while maintaining water cleanliness
Solution Approach 2:
The purification system operates autonomously by self-monitoring water quality through sensors and self-regulating purification cycle activation and duration based on detected contamination levels, eliminating the need for constant operator intervention and enabling energy-efficient operation
2Reliability
If purification substances are continuously added to maintain water quality, then water cleanliness is improved, but chemical usage increases
Solution Approach 1:
The control unit receives feedback from sensors monitoring water quality parameters and automatically adjusts chemical substance dispensation rates based on actual contamination levels, adding chemicals only when and where needed rather than continuous addition, thereby reducing overall chemical usage while maintaining water cleanliness
3Productivity
If recirculation pump operates at high flow rate to improve water circulation, then water circulation is improved, but energy consumption increases
Solution Approach 1:
The recirculation pump operates with variable flow rate controlled by the control unit, which dynamically adjusts the pump speed based on real-time water quality conditions detected by sensors, enabling the system to use high flow rates only when purification is needed and reduce flow rates during normal conditions, thereby improving water circulation efficiency while reducing energy consumption

Implementation Method 1
measuring the 'turbidity' of the water, namely by quantifying the degree to which the light passing through a liquid volume is diffracted by any particles suspended in the water
