Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current filtration systems in industrial water systems are inefficient in managing contamination and maintaining operational efficiency due to constant filtrate flow designs that do not account for varying contamination levels, leading to increased energy consumption and chemical use, and are not adaptable to changes in water quality.
Innovation Solution
An automated filtration system with a controller that adjusts flow rates based on real-time water quality parameters, activating filtration only when necessary and using a combination of sensors to monitor and adjust filtration processes, allowing for on-demand filtration and reduced chemical use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If constant filtrate flow is maintained by increasing applied pressure, then filtration efficiency is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts the applied pressure and flow rate based on real-time water quality parameters. Instead of maintaining constant high pressure, the system varies operational parameters according to actual contamination levels, reducing energy consumption when filtration demand is low while maintaining efficiency when contamination is high
Solution Approach 2:
The system changes operational parameters (pressure, flow rate) based on water quality conditions. Sensors monitor contamination levels and the controller adjusts filtration parameters accordingly, allowing the system to operate at optimal efficiency without excessive energy input
2Reliability
If filtration system is continuously activated, then water quality is maintained, but energy consumption and chemical use increase
Solution Approach 1:
The system uses periodic monitoring of water quality parameters and activates filtration only when contamination thresholds are exceeded. This on-demand operation maintains water quality reliability while avoiding continuous energy consumption and chemical dosing
Solution Approach 2:
Sensors continuously monitor water quality and provide feedback to the controller. The system activates or deactivates filtration based on this feedback, ensuring water quality is maintained only when necessary, thereby reducing unnecessary energy consumption and chemical usage
3Productivity
If side-stream filtration unit size is increased to handle high contamination, then contamination removal capacity is improved, but device complexity and cost increase
Solution Approach 1:
The system uses a dynamically adjustable flow rate through the filtration unit rather than a fixed large-capacity unit. By varying the flow rate based on contamination levels, the system achieves high contamination removal capacity only when needed, allowing a smaller, less complex filtration unit to suffice
Solution Approach 2:
The system changes the flow rate parameter through the filtration unit based on contamination measurements. This allows a compact filtration unit to handle high contamination loads by increasing flow rate when necessary, rather than requiring a permanently oversized unit

AI summary
Disclosed and claimed is a method of removing contaminants from a process stream or stabilizing a system parameter in the process stream. The method includes providing a filtration system in communication with a controller, wherein the controller is operable to automatically initiate a flow from the process stream into the filtration system when the system parameter of the process stream is within above an upper threshold value and/or below a lower threshold value; and activating the filtration system, wherein the flow comprises a flow rate through the filtration system and the controller is operable to adjust the flow rate.
