Abstract Low‐cost separation techniques are crucial for treating wastewater. Developing inexpensive membranes made from natural materials has become a popular research area in recent years. Tubular were produced by adding 10% organic additives to mixture of 80% zeolite and smectite. New composite ceramic smectite prepared using the extrusion method create plastic paste characterized XRD, SEM, EPMA, FTIR. The impact sintering temperature ( T sint , 850–950 °C) on membrane properties, such as microstructure, mechanical strength (MS), water permeability, filtration performance, was investigated. MS shrinkage rate increased with . At 950 °C, resulting exhibited high over 65 MPa, relatively low porosity 30%, appropriate filtration, permeability L·h⁻¹·m⁻ 2 ·bar⁻¹. When applied remove pollutants wastewater, this demonstrated color retention 98.4% an aqueous Evans blue‐colored solution (Effluent 1). For extensive application wastewater treatment, showed high‐efficiency level real effluent pulp industry, removing 62.4% chemical oxygen demand, 36% hardness, 82% color. Finally, ultrasonic cleaning procedure allowed restoration 70% initial after four cycles both effluents. Thanks exciting properties offered these their competitive cost less than $ 20·m −2 industrial
