Dialysis Fluid Drain Container pH Adjustment and UV Disinfection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Used dialysis fluid, particularly with high pH values, can damage septic systems and contain harmful bacteria, posing risks to wastewater treatment in these systems.
Innovation Solution
A dialysis fluid drain container system that combines used dialysis fluid with an acid, such as citric acid, to lower the pH value and includes an ultraviolet (UV) treatment to disinfect the fluid, ensuring safe disposal in septic systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If used dialysis fluid is disposed of directly in a septic system, then disposal is simple and quick, but the high pH value damages the septic system and harmful bacteria contaminate the wastewater treatment
Solution Approach 1:
The system performs preliminary treatment of the dialysis fluid by lowering pH and disinfection before disposal. Acid is added to the collection container to reduce pH, and UV light is applied to kill bacteria, so the fluid is pre-treated before entering the septic system, preventing damage and contamination
Solution Approach 2:
The patent introduces intermediary substances and processes between the dialysis fluid and the septic system. Acid serves as a chemical intermediary to neutralize high pH, and UV light acts as a physical intermediary to eliminate harmful bacteria, creating a safe transition from medical waste to septic system input
2Reliability
If acid is added to lower pH and UV treatment is applied to disinfect the fluid, then septic system safety is ensured, but the system complexity increases
Solution Approach 1:
The patent combines multiple treatment functions into a single integrated system. The collection container simultaneously serves as the mixing vessel for acid addition, the reaction chamber for pH lowering, and the target for UV disinfection, eliminating the need for separate treatment equipment and reducing overall system complexity
Solution Approach 2:
The system is designed to be self-contained and self-operating. The acid is pre-loaded in the collection container, automatic mixing occurs when fluid is added, and UV disinfection is automatically activated, requiring minimal user intervention while ensuring consistent treatment and safety
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
