Xylem Water Filtration

Abstract: This project explored the usage and effectiveness of a natural water filtration system using xylem from Picea Abies, or Norway Spruce. The project is concentrated on the region of southeast and south Asia where people suffer from water contamination, providing a concept of a water filter with comprehensive protection against waterborne diseases. The study implemented secondary research on product design, material selection, conceptual testing and followed by filtration system design. The filter successfully filtered challenged test water, leaving a clear liquid free from dirt. Additional filters were introduced, such as ceramic and metal filters to filter larger particles to prolong the lifespan of the wood filter. A solution to tackle the natural variation of the wood filter, a flexible silicone socket was developed. The final design housed all filters within a box, making it possible for easy cleaning and replacement. The product was designed to exhibit a clinical look to emphasize cleanliness, precision, and functionality. A color coding system guidedusers in assembly, with red indicating the dirty water entrance and blue indicating the exit of clean water. Materials considered for construction included recyclable, durable aluminum and transparent plastic, each with its advantages and drawbacks. The product is powered by solar energy and uses a pay-as-you- go model, offering affordability and scalability. The system includes a microcontroller that alerts for filter replacements and manages the system's operation. Potential areas of further research include real-world water testing for quality verification, addressing leakage issues, understanding the influence of cultural contexts on product acceptance, and exploring the potential benefits of pressure integration in the system. While the system performed well under controlled conditions, its effectiveness in real-world scenarios and under varying operational pressures remains to be tested.
