Abstract Membrane technology has emerged as a viable method for water purification due to the high quality of water that is produced. Flat sheet polysulfone membranes were prepared using the phase inversion method. N‐methylpyrrolidone was used as a solvent and water as a coagulant. Lantana camara of different dosages was used as the polymeric additives in the casting solution. The morphology of the prepared membranes was analyzed using scanning electron microscopy and performance of membranes was evaluated in terms of porosity, tensile strength, elongation at break, thermal stability and surface roughness. Results shows that L. camara particles are a pore former and they have the ability to improve the antifouling properties of the resultant membrane from 1.91×10 5 m −1 to 0.59×10 5 m −1 .
