Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current filter systems for removing suspended particles from liquids often clog due to particle attachment, requiring frequent maintenance and increased energy usage, which is inefficient and costly.
Innovation Solution
A filter system with synthetic low friction surface layers having specific pore sizes, treated with thermal or plasma treatment, to prevent suspended particles from attaching, allowing them to sediment and be removed separately, while smaller particles pass through, utilizing a hydrophobic layer upstream and hydrophilic layer downstream for enhanced filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If filter devices with high absorptive capacity are used to remove particles and pollutants, then the filtering effectiveness is improved, but the hydraulic conductivity decreases resulting in low fluid flow rate
Solution Approach 1:
The filter device is divided into multiple filter elements arranged in parallel within the housing. Each filter element handles a portion of the fluid flow, allowing the system to maintain high filtering effectiveness while preserving hydraulic conductivity through distributed parallel processing of the fluid stream
Solution Approach 2:
The filter elements utilize porous synthetic material with specific pore size distribution to achieve effective particle and pollutant removal while maintaining adequate fluid flow. The porous structure provides large surface area for filtration without creating excessive flow resistance
2Productivity
If filter devices with macro and micro pores are used to increase fluid flow rate, then the hydraulic conductivity is improved, but the filter devices become clogged requiring constant maintenance
Solution Approach 1:
The filter elements utilize synthetic material with specific pore size parameters (macro pores greater than 10 micrometers) that prevent particle attachment and clogging while maintaining high fluid flow rates. The parameter optimization of pore size distribution prevents both particle capture and flow restriction
3Reliability
If conventional filter devices are used to remove suspended particles, then particles are trapped on the filter surface, but the filter device becomes clogged and requires frequent maintenance
Solution Approach 1:
Instead of designing filters that capture and hold particles on their surface, the invention uses filter elements that allow particles to pass through while preventing attachment. The filter elements are designed to be easily removable and replaceable, inverting the maintenance approach from cleaning reusable filters to simple replacement of consumable elements

AI summary
The present inventive concept relates to a filter system for filtering suspended particles from a liquid, the filter system comprising a housing having an inlet for receiving liquid, and an outlet for enabling liquid to leave said housing, and a filter device arranged within the housing between the inlet and the outlet. The filter device comprises a synthetic low friction surface layer having a plurality of pores with a pore size allowing suspended particles of a size smaller than the pore size to pass through the synthetic low friction surface layer together with the liquid. The low friction surface layer prevents a majority of the suspended particles of a size larger than the pore size to attach to the filter device.
