Covered Bath Water Treatment for Volatile Compound Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating water in covered bathing establishments fail to effectively reduce the levels of volatile compounds like trichloramine and trihalomethanes, leading to atmospheric contamination and health issues for users and staff, with existing techniques only achieving partial reductions and requiring significant modifications or energy-intensive equipment.
Innovation Solution
A process involving heating and spraying water from a buffer zone into an enclosure with controlled pressure, followed by air extraction and filtration, which significantly reduces the concentration of volatile compounds, including trichloramine and trihalomethanes, by volatilizing and removing them from the water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional water treatment methods (buffer tank with filtration and disinfectant injection) are used, then water sanitation is achieved, but volatile compounds (trichloramine and trihalomethanes) are not effectively reduced, causing atmospheric contamination
Solution Approach 1:
The invention utilizes phase transition from liquid to gas (volatilization) to remove volatile compounds from water. By heating the water and spraying it into an enclosure with controlled pressure, the volatile compounds (trichloramine and trihalomethanes) transition from dissolved state in liquid phase to gas phase, where they can be extracted and removed from the system, achieving 85-97% reduction in trichloramine and 70% reduction in trihalomethanes.
Solution Approach 2:
The invention changes physical parameters (temperature and pressure) to enhance the removal of volatile compounds. Water is heated to elevated temperatures and sprayed into an enclosure with controlled pressure conditions, which alters the volatility and mass transfer characteristics of the compounds, significantly improving their removal efficiency from the water.
2Productivity
If stripping towers are used to reduce volatile compounds, then compound reduction is achieved, but the equipment becomes bulky and energy-intensive
Solution Approach 1:
The invention segments the water flow by directing only a portion of the basin water through the treatment system (spraying heated water into the enclosure), while the remaining water stays in the basin. This partial treatment approach achieves effective volatile compound reduction without requiring treatment of the entire water volume, thereby reducing equipment size and energy consumption compared to conventional stripping towers.
Solution Approach 2:
The invention introduces an intermediary enclosure with controlled pressure conditions as a medium between the water source and the final discharge. This enclosure acts as a transfer chamber where volatile compounds are efficiently removed through phase transition, replacing the need for large, energy-intensive stripping towers while achieving comparable or superior removal efficiency.
3Object-affected harmful factors
If air bubbles are injected into buffer zone to emit volatile compounds, then some reduction is achieved, but powerful and bulky pumps are required
Solution Approach 1:
The invention replaces the mechanical bubble injection system (requiring powerful pumps) with a thermal and pressure-based spray system. Instead of forcing air bubbles through water mechanically, the system heats water and sprays it into a controlled-pressure enclosure, allowing volatile compounds to naturally volatilize and be extracted, thereby eliminating the need for high-power pumping equipment.
