Solution Overview
Problem
Existing water treatment systems face challenges in achieving stable and optimal intake of air/ozone mixtures, minimizing deposition and contamination on UV radiation components, optimizing energy and chemical usage, and enhancing operational control when treating water contaminated with microorganisms and micropollutants.
Innovation Solution
The system incorporates a reactor with two reaction chambers, a UV lamp, and an air/ozone conduit, allowing air to form ozone under UV radiation, which is then fed into the water treatment process, along with recirculation and fresh water integration to maintain constant flow and pressure, and includes sensors and controllable pumps for optimized operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air/ozone mixture is fed into process water via inlet point or bypass branching with injection nozzle, then water treatment is achieved, but intake performance becomes unstable due to pressure fluctuations in main water circuit
Solution Approach 1:
The system divides the water flow into two separate circuits: a recirculation circuit that passes through the reactor and a bypass that maintains stable pressure conditions. This segmentation isolates the ozone injection system from pressure fluctuations in the main water circuit, ensuring stable intake performance.
Solution Approach 2:
The system uses a controllable pump in the recirculation circuit that can respond to pressure conditions, maintaining stable operation of the ozone injection system by adjusting flow rates to compensate for pressure variations in the main circuit.
2Reliability
If UV lamp is used for water treatment, then disinfection and degradation of micropollutants is achieved, but deposition and contamination on the outside of quartz tube occurs, reducing UV radiation efficiency
Solution Approach 1:
The system performs preliminary cleaning of the quartz tube by circulating cleaning solutions through the reactor before UV treatment begins, preventing deposition buildup that would reduce UV transmission efficiency.
Solution Approach 2:
The system implements continuous or periodic cleaning cycles that maintain the quartz tube surface cleanliness throughout operation, ensuring uninterrupted UV radiation efficiency without requiring system shutdowns for maintenance.
3Reliability
If conventional water treatment system is used, then water purification is achieved, but energy and chemical consumption is high, increasing operational costs
Solution Approach 1:
The system recirculates treated water back through the reactor, allowing multiple passes through the UV and ozone treatment zones. This increases treatment efficiency and reduces the need for additional chemicals and energy input compared to single-pass conventional systems.
4Reliability
If conventional water treatment system is used, then water purification is achieved, but operational control and maintenance capability is limited
Solution Approach 1:
The system incorporates sensors and controllable pumps that enable automated monitoring and adjustment of treatment parameters, improving operational control capability while maintaining water purification quality.
Solution Approach 2:
The system implements self-cleaning functions and automated maintenance routines that reduce manual intervention requirements, enhancing operational control and maintenance capability.
