Conical Filter Sediment Separation Storm Water
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional silt protection devices around storm drain catch basins are laborious, costly, and often ineffective during heavy storms, while sediment ponds require efficient filtration and treatment of discharged water to meet regulatory standards.
Innovation Solution
A multipurpose conical filter with a surrounding wall structure and array of openings is used to filter storm water before it enters a catch basin or is pumped from a sediment pond, utilizing stones to separate sediment and allow clear water to pass through, with the option to lift and clean the collected solids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional silt fences are erected around catch basins, then protection against sediment entry is provided, but installation becomes laborious, time-consuming and expensive
Solution Approach 1:
The silt fence system is divided into modular sections that can be quickly assembled and deployed around catch basins, reducing installation time while maintaining protection effectiveness
Solution Approach 2:
A pre-assembled frame structure serves as an intermediary between the ground and the silt fence fabric, enabling rapid deployment without requiring complex on-site construction of support structures
2Reliability
If conventional silt fences are used around catch basins, then sediment protection is intended, but the fences often fail during heavy storms allowing substantial volumes of silt and debris to enter
Solution Approach 1:
The frame structure is pre-assembled with reinforced connections before deployment, ensuring structural integrity is established in advance to withstand heavy storm conditions
Solution Approach 2:
The system combines a rigid frame structure with durable silt fence fabric to create a composite system that maintains structural strength during heavy storms while effectively filtering sediment
3Reliability
If water is pumped from sediment ponds for discharge, then sediment removal is required to meet regulations, but filtering and treatment processes are complex and costly
Solution Approach 1:
The conical filter serves multiple functions: it filters sediment from pumped water, provides structural support for the discharge system, and can be easily removed and cleaned, simplifying the overall filtration process while ensuring regulatory compliance
Solution Approach 2:
Instead of using complex multi-stage filtration systems, the invention inverts the approach by using a simple conical shape with a closed bottom that relies on gravity and geometry to separate and collect sediment, reducing system complexity while maintaining effectiveness
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 conical filter effectively reduces sediment and debris entry into catch basins, lowers installation and maintenance costs, and ensures compliance with regulations by efficiently filtering water from sediment ponds, thereby protecting infrastructure and the environment.
Implementation Method 1
Water from the sediment pond is pumped into a top portion of the conical filter. The pump forces the water downwardly through the conical filter. This restriction of flow causes the water entering the interior of the conical filter to be expelled out the sides or the surrounding wall structure of the conical filter having the array of openings. This causes the sediment, including sand, silt, fines and mud, etc. to be separated and trapped interiorly within the conical filter.
Implementation Method 2
a pump that is employed to pump the water from the sediment pond. Water from the sediment pond is pumped into a top portion of the conical filter. The pump forces the water downwardly through the conical filter.
