Membrane fouling is a significant drawback in the implementation of membrane processes. To tackle this problem, the polyvinyl chloride (PVC) membrane was made by non-solvent induced phase separation (NIPS) and then placed on the 3D printed wavy support using a vacuum to prepare the patterned membrane. Characteristic tests were applied to study the properties of flat and wavy membranes. Fouling experiments were conducted using bovine serum albumin (BSA) solution, sodium alginate (SA) solution, and fruit-roll wastewater to evaluate the level of fouling in membranes. The total fouling ratio (TFR) for the flat membrane in the presence of BSA solution, SA solution, and fruit-roll wastewater was achieved 30%, 64%, and 53%, respectively. This ratio for the wavy membrane was 15%, 52%, and 36%, respectively. The solutions of sodium hypochlorite (NaOCl) and sodium dodecyl sulfate (SDS) were utilized for the chemical cleaning of membranes. NaOCl solution exhibited the highest cleaning efficiency at 94% for wavy membrane and 85% for flat membrane.
