Comparative between vertical and horizontal panel orientation for optimum membrane surface patterning effect

It is well-known that aeration an efficient method to reduce fouling formation for the membrane-based system. In recent years, membrane surface patterning was claimed able increase efficiency of by enhancing scouring action air bubbles. Many studies reported combination and showed excellent performance system various applications. Nevertheless, here another known as panel orientation evaluated observe microalgae harvesting application Chlorella vulgaris filtration. To date, none literature discussed about control crossflow filtration The aim this study determine most optimum would maximize effect, well improvement a combined technique. Two types membranes were fabricated in which flat (FM) corrugated (CM). FM has smooth (without method) while CM hills valleys topography (with method). First, effect measured find out tilting angle higher permeability. 0° (vertical), 15°, 30°, 45°, 60°, 75° 90° (horizontal) aerated under constant TMP (10 kPa). Results permeability increased from 90°, with than all applied tilted angles. Even though highest both are at horizontal but, increment vertical panel. Hence, effects further operating transmembrane pressures (2.5, 5, 7.5, 10, 12.5, 15, 17.5 19 kPa) CM. conclude, due compared TMPs values (from 2.5 till 12.5
