Low-Cost Household Water Filtration: Efficiency, Limitations And Optimization a Performance Analysis Of Diy Multi-Layer Filtration System
Author(s): Adhrit Didwania*
Water contamination causes 3.4 million deaths annually, with 2.2 billion people lacking access to safe drinking water. This research investigates the development and efficacy of a low-cost water filtration system constructed from readily available materials for use in emergency situations and resource-limited environments. The system employs a multi- layer filtration design incorporating activated charcoal, sand, and gravel within a repurposed plastic container, with a total cost under $15 USD. Performance testing with three distinct water samples demonstrated significant improvements in water quality parameters including turbidity reduction (87.6%, 95% CI: 84.2-91.0%), pH normalization (to 7.1- 7.4 range), and odor removal. Microbial analysis showed moderate reduction in total coliform counts (68.3%) but insufficient pathogen removal for safe drinking without additional disinfection... Read More»
