Electrocoagulation Cartridge for Rapid Electrode Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrocoagulation systems require frequent replacement of electrodes, which disrupts continuous treatment processes and can lead to accumulation of waste water during maintenance, especially in industrial settings where water purification is critical.
Innovation Solution
A flow-through assembly with a removable cartridge containing sacrificial electrodes, allowing for easy and rapid replacement within a chamber that maintains a liquid-tight seal, enabling continuous treatment without halting the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrodes are used in electrocoagulation systems, then water purification is achieved, but electrodes require frequent replacement which disrupts continuous treatment processes
Solution Approach 1:
The electrode assembly is segmented into a removable cartridge format, allowing the electrodes to be replaced as a complete unit without disrupting the continuous treatment process. The cartridge can be quickly removed and replaced through a simple extraction mechanism, maintaining system reliability while minimizing downtime.
Solution Approach 2:
Electrodes are pre-assembled in cartridges before being installed in the treatment system. This preliminary assembly allows for easy replacement of entire cartridge units rather than individual electrodes, reducing replacement time and maintaining continuous operation capability.
2Productivity
If electrodes are replaced during operation, then fresh electrodes are installed, but waste water accumulates during maintenance
Solution Approach 1:
The removable cartridge design enables electrode replacement without interrupting the water treatment process. The system maintains continuous operation by allowing cartridge exchange while water flow continues uninterrupted, preventing waste water accumulation and maintaining productivity.
3Manufacturing precision
If high levels of electrolyte are added to facilitate flocculation, then particle removal is improved, but dissolved electrolyte remains in the treated water
Solution Approach 1:
The electrocoagulation system uses electrical energy to generate counterions through electrolysis of water itself, rather than requiring external electrolyte addition. The process self-regulates by using the water in the system as the electrolyte source, achieving effective particle removal without introducing excess dissolved electrolyte into the treated water.

Function Achieved in This Case
Facilitates continuous electrocoagulation treatment by allowing for quick electrode replacement, ensuring uninterrupted water purification and reducing the risk of pollution in industrial settings, such as food manufacturing plants and polymer recycling facilities.
Implementation Method 1
electrochemical dissolution of an electrode by electrolytic oxidation with OH− to form counterions of high charge, at the anodes
Implementation Method 2
an electrical field being set up across the sacrificial electrodes, causing them to have cathodic and anodic surfaces and causing a current to flow between them
Implementation Method 3
hydrogen bubbles being generated at the cathodic surfaces
Implementation Method 4
the presence of gas bubbles from the cathode, subsequently entrained within the resulting floc of particulate matter, may assist in removal of the particulate matter by flotation and bulk separation

AI summary
Apparatus for Treatment of Liquid A flow-through assembly for electrocoagulation treatment of a liquid has a replaceable cartridge with sacrificial electrodes held in a chamber arranged for flow of the liquid through and over the sacrificial electrodes. The chamber has a pivoting door which can be opened for removal and replacement or refurbishing of the cartridge. One electrode for providing a current to electrochemically dissolve the sacrificial electrodes is located in the chamber with a second electrode on the inner face of the door, with the sacrificial electrodes located between the current-providing electrodes with chamber door closed in use.
