Abstract. Water pollution by synthetic dyes such as Malachite Green (MG) poses a significant environmental challenge, particularly in developing countries. This study aims to create eco-friendly ceramic membranes from natural clay sourced from the Draa-Tafilalet region of Morocco to filtrate MG-contaminated water. The membranes were fabricated via a dry pressing method using varying proportions (0–12 wt%) of date palm pits as an organic pore-forming agent. The Physicochemical characterizations, revealed that increasing the additive content enhances membrane porosity while decreasing mechanical strength. With the optimal formulation identified at 6 wt% and sintering at 1000°C. The elaborated membrane was applied to the frontal microfiltration of MG dye solution. UV-Vis spectroscopic analysis confirmed high dye removal efficiency, with more than 70% retention after 200 minutes of filtration. Meanwhile, the permeate flow gradually decreased due to fouling, revealing a trade-off between filtration efficiency and flow rate. The results demonstrate that natural clay-based ceramic membranes, modified with agricultural waste, provide an environmentally friendly and cost-efficient approach for dye removal in water treatment systems.
