Abstract

This research looks at how to constantly remove nitrate from water using fine powder brick, which is a cheap and eco-friendly material. The paper addresses the growing concern of nitrate contamination in water sources, particularly from agricultural runoff and industrial discharge, which generates significant health risks such as methemoglobinemia and environmental harm. The main goal of the study is to see how well fine powder brick works under different conditions, like starting nitrate levels (7–21 mg/L), flow rates (4–16 L/hr), and the depth of the adsorbent bed (6–18 cm). Monitoring the effluent-to-influent concentration ratio (Co/Ce) over time showed breakthrough behavior. The results indicated that nitrate removal worked better at slower flow rates, lower starting concentrations, and shallower bed depths because there was more time for the nitrate to come into contact with the adsorbent and a larger area for it to stick to. The study emphasized the potential of recycling construction waste as an adsorbent for nitrate removal in continuous flow systems and provided helpful suggestions for optimizing fixed-bed column operations in real water treatment applications.
