N2 - The nitrate removal performance with a biosorbent based on Moringa oleifera Lam seeds was evaluated in the surface waters of the lower basin of the Chillón River - Puente Piedra District Lima, Peru in 2023. Initially, the water sample was characterized, obtaining the initial physicochemical parameters such as pH (6.5), nitrates (36.8 mg / L) and turbidity (23.7 NTU). A 23 factorial design was used, with 2 levels (high and low) and 3 variables pH (5 and 8), time (20 and 40 min) and moringa dose (1 and 2 g / 100 mL), being a total of8 treatments with 2 repetitions. It was found that pH, time and dose significantly influence the nitrate removal performance by applying Moringa oleifera Lam seeds as a bioadsorbent. A percentage of 73.32% was achieved with a pH of 8, a time of 20 minutes and a dose of 1 g/100 mL. Moringa seed is recommended as a sustainable, low-cost and eco-friendly alternative to absorbent chemical products.
