Evaluation of Multi-Coloured Filter Containers for Water Quality

This study examines the effectiveness of multi-coloured filter containers, black (BK), blue (BL), and transparent (TR), in improving water quality, focusing on indicators such as turbidity, Total Suspended Solids (TSS), pH, electrical conductivity, total alkalinity, calcium, and iron. The investigation aims to determine whether container colour impacts filtration performance. Water samples were drawn from a shallow, untreated well at the Federal Polytechnic, Ado Ekiti, known for poor water quality and contaminant levels exceeding WHO standards, providing an ideal source for testing filtration efficacy. Identical filter media were installed in each container to ensure consistency, and samples were periodically tested over time. Results indicated that the blue (BL) container provided the most effective overall filtration, demonstrating superior turbidity reduction and stable water quality improvements. Black and transparent containers showed effectiveness in specific areas but were generally less consistent than blue ones. These findings suggest that container colour, likely influenced by factors such as light transmission, impacts filtration outcomes. The study concludes that blue containers offer the best performance for enhancing water quality, and future research should explore additional colours and materials to improve contaminant removal further and achieve reliable water quality standards.
