Tubular Filter Pool Backwash Filtration Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Primary filtration assemblies for pool water fail to remove fine particulates, preventing effective recycling of pool water through secondary filtration.
Innovation Solution
A cylindrical housing with a tubular filter and endcap configuration, connected to both a primary filtration device and the pool, allowing water to pass through the tubular filter before reentering the pool, ensuring finer filtration than primary systems alone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a primary filtration assembly is used for pool water, then basic filtration is achieved, but fine particulates cannot be removed
Solution Approach 1:
The filtration system is divided into two distinct segments: a primary filtration assembly for basic filtration and a secondary tubular filter assembly for fine particulate removal. Each assembly handles a specific filtration stage, allowing the system to achieve high filtration precision without overwhelming complexity in a single component.
Solution Approach 2:
The invention adds a secondary filtration dimension by introducing the tubular filter assembly that operates in parallel with the primary filtration system. This additional filtration layer addresses fine particulates that the primary system misses, effectively adding another dimension of filtration capability.
2Productivity
If primary filtration only is used, then system simplicity is maintained, but water recycling effectiveness is insufficient
Solution Approach 1:
The system performs preliminary filtration through the primary assembly to remove larger particulates, then directs water through the secondary tubular filter for fine particulate removal. This staged preliminary action ensures that the secondary filter receives pre-conditioned water, improving overall recycling effectiveness while managing complexity through systematic progression.
Solution Approach 2:
The invention introduces an intermediary component - the secondary tubular filter assembly - that mediates between the primary filtration system and the water recycling process. This intermediary handles the specific task of fine particulate removal, enabling effective water recycling without requiring complete system redesign.
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 solution enables the removal of particulates too small for primary filtration systems, purifying pool water to a higher extent, allowing for effective recycling and reuse.
Implementation Method 1
a tubular filter, both ends open... The internal space of the tubular filter is in fluidic communication with the pool... Water that is pumped from the pool through the primary filtration device thus passes through the tubular filter prior to reentering the pool

AI summary
A pool backwash secondary filtration assembly for filtering water from a pool for reuse includes a housing, which is cylindrical and which has a first end that is open. A tubular filter is positionable within the housing and an endcap is selectively attachable to the housing to close the first end. A biaser attached to the endcap biases a plug into the tubular filter upon attachment of the endcap to the housing and the tubular filter is sealingly engaged to a second end of the housing. First and second connectors are attached to the endcap and to the second end of the housing, respectively, and are attachable to a first and second conduits, respectively, which extend from a primary filtration device and a pool, respectively. Water that is pumped from the pool through the primary filtration device thus passes through the tubular filter prior to reentering the pool.
