Aeration Control Valve System for Water Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water treatment systems using venturi for aeration suffer from noise, rattling, and flooding during backwash cycles, waste of water for air introduction, and incomplete air regeneration, leading to inefficient operation and potential contamination.
Innovation Solution
An aeration control valve system that pumps air into the water treatment system at atmospheric or higher pressures, allowing for controlled air release and regeneration without using water, thus preventing sudden air escapes and maintaining air charge during service cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a venturi is used to provide aeration by directing water through it, then air is drawn into the filter tank, but excessive water is wasted (1 gallon of water to introduce 1.75 gallons of air)
Solution Approach 1:
The patent extracts the air introduction function from the water flow path by using a separate air pump to deliver air directly to the top of the tank, eliminating the need to waste water through the venturi for aeration purposes
Solution Approach 2:
The control valve is designed to perform multiple functions: directing water for filtration, controlling air intake for aeration, managing backwash cycles, and regulating air release during air draw cycles, all through a single integrated system
2Quantity of substance
If compressed air is released suddenly during backwash cycle, then air regeneration is achieved, but noise, rattling, and flooding occur along with drain line damage
Solution Approach 1:
The system performs preliminary air release during the air draw cycle before the backwash cycle begins, so that when backwash occurs there is no compressed air charge to escape suddenly, preventing noise, rattling, and flooding
Solution Approach 2:
The control valve manages air release in periodic cycles - releasing air during air draw cycles and maintaining air charge during service cycles, creating a rhythmic operation that prevents harmful sudden releases
3Quantity of substance
If rapid air escape occurs during backwash, then air is vented from the tank, but filter media jumps vertically and is lost through the drain line
Solution Approach 1:
The control valve releases compressed air during the air draw cycle before backwash begins, eliminating the air charge that would otherwise cause filter media to jump vertically during backwash, thereby preventing media loss through the drain line
4Quantity of substance
If a larger tank is used to prevent filter media loss, then more air charge is available, but more water goes to drain during air draw cycle and filter media cost increases
Solution Approach 1:
The system changes the timing parameter of air release by performing it during the air draw cycle rather than during backwash, allowing adequate air charge to be available without requiring a larger tank, thus reducing water waste and media costs
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system reduces noise and flooding, conserves water, and enables frequent air regeneration while maintaining air charge, enhancing the efficiency and reliability of water treatment processes.
Implementation Method 1
the control valve may perform an air draw cycle by directing water through a venturi coupled to an air inlet such that the venturi draws air into the top of the filter tank

AI summary
An aeration control valve system may be used with a water treatment system to control aeration and flow of water in accordance with various operating cycles. The aeration control valve system pumps air into the water treatment system to provide an air charge for aerating the water to facilitate water treatment. The aeration control valve system may pump air into the water treatment system at atmospheric pressure or may pump air at higher pressures such that the air may be recharged while also treating the water. The aeration control valve may also control the release of air from the water treatment system. The operating cycles may include, for example, a service cycle, a backwash cycle, an air regeneration cycle, a service/air charge cycle, an air release cycle, and a rinse cycle.
