Scenario: A small community is facing a challenge with contaminated groundwater. The contaminants include a mixture of organic pollutants and heavy metals. The existing water treatment plant uses a single-stage filtration system that is not effective in removing these pollutants.
Task: Design a hybrid system that could be used to treat the contaminated groundwater. Consider the following:
A possible hybrid system for this scenario could combine:
The combined system would first use activated carbon filtration to remove the organic pollutants. The water would then be passed through an ion exchange filter to remove the heavy metals.
Potential Benefits:
Potential Challenges:
This is just one possible hybrid system design, and the specific technologies and their configuration would need to be tailored to the specific characteristics of the contaminated groundwater and the community's needs.
