Pool Overflow Channel Air Stripping for Chloramine Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for removing volatile disinfection by-products (DBPs) from swimming pool water, such as chloramines and halomethanes, are inefficient as they accumulate near the water surface and are not effectively addressed by traditional HVAC ventilation systems, leading to health issues for users and staff.
Innovation Solution
A system comprising a main channel with air suction holes and an air insufflation device that forces the release of volatile substances into a confined space for efficient removal, using a suction duct to collect and discharge these substances outside the pool facility, integrated with the pool's overflow and deck water systems to treat all recirculating water and ambient air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional HVAC ventilation systems are used to remove volatile substances, then the entire environmental volume is covered, but the volatile substances accumulate in the breath zone near the water surface and are not effectively removed
Solution Approach 1:
The invention applies local quality by positioning air suction holes specifically at the breath zone level near the water surface, rather than using uniform ventilation throughout the entire environmental volume. This localized approach concentrates removal capacity where DBPs accumulate most, improving efficiency without requiring system-wide increases in ventilation capacity.
Solution Approach 2:
The invention introduces a new spatial dimension for volatile substance removal by placing suction holes at the water surface level (breath zone), creating a horizontal removal plane that complements traditional vertical HVAC airflow patterns. This dimensional addition allows direct interception of DBPs at their source accumulation point.
2Temperature
If air vents are located in the upper part of the facility for HVAC systems, then temperature and humidity regulation is achieved, but the vents are away from the region most affected by DBP accumulation
Solution Approach 1:
The invention merges the functions of temperature/humidity control and DBP removal by integrating air suction holes into the existing HVAC ventilation system structure. The same ventilation infrastructure that regulates environmental conditions now also captures volatile substances at the breath zone, combining two previously separate functions into one unified system.
Solution Approach 2:
The ventilation system is enhanced to perform multiple functions: traditional temperature and humidity regulation plus targeted DBP removal at the breath zone. The air suction holes serve dual purposes by being positioned to both capture volatile substances and participate in the overall environmental air circulation required for thermal comfort.
3Adaptability or versatility
If environmental ventilation systems cover the entire environmental volume, then comprehensive air treatment is provided, but they are not efficient in removing volatile substances that remain near the free water surface
Solution Approach 1:
The ventilation function is segmented into two distinct components: traditional bulk environmental ventilation for overall air treatment, and localized air suction holes at the breath zone for targeted DBP removal. This segmentation allows each component to optimize its specific function without compromising the other, improving overall system efficiency.
Solution Approach 2:
The air suction holes perform preliminary action by capturing volatile substances at the breath zone before they can disperse throughout the entire environmental volume. This early interception at the source accumulation point prevents DBPs from mixing with the general ambient air, making removal more efficient.
