Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wastewater treatment systems, such as clarifiers, skimmers, and oil-water and sludge separators, are large, unwieldy, require significant energy, and create turbulence, making them difficult to modify, expand, and transport, and are inefficient in removing suspended and dissolved solids.
Innovation Solution
A passive gravity filter cell with a basin and angled sidewalls, a wide shallow inlet, and a discharge pipe, equipped with a flap and charged particle precipitators, allowing for calm flow without turbulence, low energy use, and modular design for adjustable filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional clarifiers are used for wastewater treatment, then suspended solids can be removed, but the devices become large, unwieldy, and require significant acreage
Solution Approach 1:
The filter cell is divided into distinct functional zones including an inlet zone, filtration zone with media bed, and outlet zone. This segmentation allows each zone to perform its specific function efficiently while maintaining a compact overall structure that reduces acreage requirements compared to traditional clarifiers.
Solution Approach 2:
The invention transitions from horizontal spreading of wastewater treatment (traditional clarifiers requiring large surface area) to vertical filtration through multiple media layers. This dimensional change allows high removal efficiency to be achieved in a compact footprint with reduced acreage requirements.
2Productivity
If traditional clarifiers with mechanical means are used, then continuous movement of wastewater can be achieved, but the devices become unwieldy and difficult to transport
Solution Approach 1:
The filter cell utilizes gravity-driven flow and passive filtration mechanisms without requiring mechanical pumps or moving parts. Wastewater continuously flows through the system driven by gravity, eliminating the need for mechanical means while maintaining productivity. This passive design makes the device portable and easy to transport.
3Manufacturing precision
If traditional clarifiers are used, then wastewater can be treated, but large electrical energy is required to pump and stir the wastewater
Solution Approach 1:
The system employs gravity-driven flow through the filtration media without requiring electrical pumps. The filtration process itself occurs passively as wastewater percolates through the media bed, eliminating the need for electrical energy to drive the treatment process while maintaining effectiveness.
Solution Approach 2:
The invention replaces mechanical stirring and pumping systems with gravity-driven flow and passive filtration. The natural gravitational force moves wastewater through the filter media, substituting mechanical energy consumption with a passive physical process that requires no electrical input.
4Manufacturing precision
If skimmers are used to collect floating contaminants, then the contaminated top layer can be removed, but flow is restricted and turbulent flow patterns are created
Solution Approach 1:
The filter cell extracts and removes floating contaminants at the surface layer as wastewater enters the filtration zone. The design allows this extraction to occur without restricting overall flow or creating turbulence, as the filtration process continues smoothly through the media bed below the surface.
5Manufacturing precision
If oil-water and sludge separators with baffles are used, then separation can be achieved, but heavy turbulence is created that suspends solids
Solution Approach 1:
The invention replaces mechanical baffle systems that create turbulence with passive gravity-based separation and filtration. Wastewater flows calmly through the filter media without mechanical disruption, allowing solids to settle naturally and be filtered without turbulent suspension while maintaining separation efficiency.
