The Core Product: A Gravity-Fed Water Filtration System
The main physical solution is a multi-stage water filtration system designed to be effective, durable, and suitable for rural environments without reliable electricity.
Input
Contaminated water is poured into the top chamber, where it begins the process of filtration and purification.
Sand & Gravel Filtration:
The water flows through layers of fine sand, coarse sand, and gravel, which physically trap dirt, sediment, and some bacteria.
Biological Purification:
A natural biological layer (biofilm) forms in the sand, which breaks down and consumes harmful pathogens.
Enhanced Purification:
ChatGPT said: Activated charcoal is used to eliminate unpleasant odors and further purify the water by trapping impurities and harmful substances.
Final Filtration:
A hollow fiber membrane filter is attached to remove 99.9% of the remaining harmful bacteria and pathogens, ensuring the water is safe to drink.
Output:
The clean, purified water is collected in the lower chamber, safely stored, and conveniently dispensed through a tap for easy use.
