Domestic Water Filter for Treatment of Arsenic Contaminated Water

Abstract

The feasibility and efficacy of continuous up flow filter packed with Shelled Moringa Oleifera Seed (SMOS) powder for the evacuation of As(V) from polluted water was explored by varying SMOS dose, initial As(V) intensity, and adsorbate flow rate. The finding from fixed column operations depicted that highest As(V) uptake, breakthrough, and saturation time improved with rise in SMOS dosage and with decline in volumetric flow rate. The highest As (V) uptake attained was 55.41 μg g-1 at 100 μg L-1 As(V) intensity, 6 g of SMOS, and flow rate of 2 mL min-1. The breakthrough curves of As(V) removal were modeled by Thomas model and results depicted that the Thomas model delivers excellent similarity with experimental data. From practical and economic view, the filter packed with SMOS might be exceptionally employed as a sustainable and cost-effective strategy for the evacuation of As(V) in polluted water for rural household applications.
