ABSTRACT:
This study evaluates a low-cost, sustainable filtration system using rice husk ash (RHA) enriched with Ocimum sanctum (Tulsi) for pond water purification. Seven pond samples (A–G) were assessed before and after treatment. Key parameters showed significant improvement: pH increased from acidic (5.62–6.94) to neutral–alkaline (6.11–8.21); turbidity was reduced by 72–90%; color and odor shifted from “disagreeable” to “agreeable”; and bacterial contamination was eliminated in all treated ponds. Total dissolved solids and conductivity exhibited minor reductions (~2–6%), confirming selective particulate removal without excessive ionic depletion. Results align with literature where RHA-based filters achieved up to 95% turbidity reduction and improved water quality metrics. The synergistic combination of RHA’s high surface-area silica and Tulsi’s antimicrobial properties underscores the filtration system’s efficacy. This eco-friendly, affordable approach demonstrates its potential for sustainable water treatment in rural and resource-limited contexts. Future work will optimize media ratios and assess long-term performance.
