Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water filtration systems for aquatics and recreational facilities face challenges in achieving uniform fluid flow distribution, which can lead to inefficient filtration and increased particulate media use, due to turbulent flow and uneven coating of particulate media on filter elements.
Innovation Solution
A regenerative media filter system with a diffuser having a conduit with apertures that reduce flow velocity by at least 50% and provide a uniform flow distribution, positioned based on the ratio of the vessel's height to diameter and radius of curvature, ensuring that the flow velocity exceeds the settling velocity of particulate media, allowing for effective coating and filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a diffuser is positioned to reduce flow velocity by at least 50% and provide uniform flow distribution, then filtration efficiency is improved and particulate media use is reduced, but the device complexity increases due to precise positioning requirements based on height-to-diameter ratio and radius of curvature
Solution Approach 1:
The patent applies parameter changes by optimizing the diffuser position based on specific geometric parameters of the filter vessel (height-to-diameter ratio and radius of curvature). By establishing quantitative relationships between these parameters and the optimal diffuser position, the system achieves uniform flow distribution and reduced media consumption without requiring complex control mechanisms. This transforms a potentially complex positioning problem into a standardized parameter-based solution.
2Stability of the object's composition
If the diffuser position is optimized based on height-to-diameter ratio and radius of curvature to achieve uniform flow distribution, then media coating uniformity is improved, but the ease of manufacture decreases due to customized positioning requirements
Solution Approach 1:
The patent establishes design parameters (height-to-diameter ratio and radius of curvature) that determine optimal diffuser positioning. By providing calculation methods and guidelines for determining the optimal position based on these parameters, the invention enables manufacturers to achieve uniform media coating through standardized design procedures rather than trial-and-error approaches, thereby improving ease of manufacture while maintaining coating uniformity.
3Productivity
If the diffuser aperture size and position are optimized to maintain sufficient water pressure for efficient filtration, then filtration performance is improved, but the loss of substance increases due to reduced particulate media usage
Solution Approach 1:
The patent optimizes the diffuser aperture characteristics (size, position, and configuration) to achieve a balance between maintaining sufficient water pressure for effective filtration and reducing particulate media consumption. By carefully selecting aperture parameters, the system ensures that water flow maintains the necessary velocity and pressure to support media particles and achieve effective filtration, while the uniform flow distribution prevents excessive media usage and reduces breakthrough.

AI summary
Water filtration systems are disclosed. The water filtration systems include a regenerative media filter vessel comprising a housing, an inlet, and an outlet, a diffuser fluidly connected to the inlet and disposed within the regenerative media filter vessel, and at least one pump configured to direct water through the water filtration system. The housing of the regenerative media filter vessel comprises a concave lower portion centered about a vertical axis of the vessel. The position of the diffuser along a height of the regenerative media filter vessel is determined by at least a ratio of the height to an inner diameter of the regenerative media filter vessel and a radius of curvature of the concave lower portion. A regenerative media filter including a diffuser having asymmetrically spaced apertures is also disclosed.
