Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid treatment systems face issues with precipitate buildup on surfaces, leading to reduced efficiency and increased maintenance costs due to frequent mechanical or chemical removal requirements, which can hinder the process and cause downtime.
Innovation Solution
A dasher assembly with cylindrical actuator rods and a dasher equipped with teeth is used to scrape and remove precipitates from the interior surface of a water treatment chamber, utilizing a mechanical actuator for linear translation and an electrolysis rod to separate ions, allowing for efficient purging of precipitates without obstructing fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical or chemical removal methods are used to remove precipitates, then the surface can be cleaned, but the process requires frequent maintenance and causes downtime
Solution Approach 1:
The system uses the water treatment process itself to generate the cleaning action. The electrolysis rod creates ion separation that prevents precipitate adhesion, and the normal water flow mechanically flushes away loosened precipitates during regular operation, eliminating the need for separate maintenance operations
Solution Approach 2:
The electrolysis rod continuously prevents precipitate adhesion by maintaining ion separation at the surface during normal operation, addressing the cleaning need before precipitates can firmly attach and require removal
2Reliability
If chemicals are used to prevent precipitation, then precipitate buildup is reduced, but other parts of the process are hindered
Solution Approach 1:
The system replaces chemical prevention methods with a physical/electrical mechanism. The electrolysis rod uses electrical current to create ion separation that prevents precipitate adhesion, substituting mechanical/electrical action for chemical additives and avoiding interference with other process components
Solution Approach 2:
The system changes the electrical parameters at the surface through electrolysis, creating a localized electrical field that prevents precipitate adhesion without altering the chemical composition of the water or interfering with other process parameters
3Reliability
If flow changes are used to prevent precipitation, then precipitate buildup is reduced, but process efficiency is reduced
Solution Approach 1:
The system changes the electrical parameter at the surface through electrolysis rather than changing flow parameters. This creates ion separation that prevents precipitate adhesion while maintaining normal flow rates and process efficiency

Data Source
AI summary
The present disclosure comprises devices, systems and methods for the removal of a precipitate from a surface of a water treatment chamber using a dasher assembly having two cylindrical actuator rods connected to a dasher for scraping an interior surface of the water treatment chamber. The water treatment chamber has an enclosed first end, an enclosed second end, and an electrolysis rod extending linearly therein. The two cylindrical actuator rods extend linearly within the water treatment chamber and pass through the enclosed first end so that portions of the two cylindrical actuator rods are within the water treatment chamber and portions are outside the water treatment chamber. The dasher includes an aperture therethrough so the electrolysis rod can pass through the aperture and allow the dasher to translate from a first location and a second location by translation of the two cylindrical actuator rods via a mechanical actuator. The dasher may include teeth extending from an outer edge of the dasher to score the precipitate as it translates from the first location to the second location. The dasher assembly is controlled manually and/or by an automated control system.
