Solution Overview
Problem
Current water purification methods are inadequate in managing sudden and time-limited increases in contaminant concentrations, leading to breakthroughs and unwanted desorption of pollutants in tap water, with existing systems often resulting in inefficient removal and premature exhaustion of adsorption materials.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single adsorption facility is used for continuous water purification, then the system structure is simple, but it cannot effectively manage sudden contaminant concentration increases leading to breakthroughs and premature exhaustion
Solution Approach 1:
The adsorption system is divided into two separate facilities: a peak load adsorption facility designed to handle sudden contaminant concentration increases, and a base load adsorption facility for continuous operation. This segmentation allows each facility to be optimized for its specific function, improving overall reliability without requiring a single overly complex system to handle all scenarios.
Solution Approach 2:
The peak load adsorption facility is positioned upstream to intercept and attenuate contaminant concentration peaks before they reach the base load facility. This preliminary action prevents breakthroughs in the main system and extends the service life of the base load adsorption material by avoiding premature exhaustion from handling peak loads.
2Reliability
If adsorption material is used to remove contaminants, then purification effectiveness is achieved, but the material becomes exhausted prematurely during concentration peaks requiring frequent replacement
Solution Approach 1:
The peak load adsorption facility performs preliminary interception of contaminant concentration peaks, preventing these high-concentration loads from reaching and exhausting the base load adsorption material. This extends the service life of the base load material and reduces replacement frequency.
Solution Approach 2:
The peak load adsorption facility is designed to be replaced or regenerated more frequently than the base load facility, as it handles the contaminant peaks. This allows the expensive base load material to be preserved and used for longer periods, optimizing the overall consumption and replacement strategy of adsorption materials in the system.
3Productivity
If contaminant concentration peaks are allowed to pass through, then the system operates continuously without interruption, but breakthroughs occur contaminating the purified water
Solution Approach 1:
The peak load adsorption facility is positioned upstream to intercept contaminant concentration peaks before they can cause breakthroughs in the purified water. This preliminary interception maintains continuous operation of the base load facility while preventing harmful contaminant release into the treated water stream.
Solution Approach 2:
The peak load adsorption facility acts as an intermediary between the raw water input and the base load facility. It absorbs and attenuates contaminant concentration peaks, serving as a protective buffer that prevents breakthroughs while allowing the base load facility to continue operating continuously at its optimal design point.
