Between the 26th and 28th of April the annual Engineering with Membranes was held in Singapore organised by the Singapore Membrane Technology Centre (SMTC). The main goal of the conference was to share knowledge on recent advances in membrane science and technology. Leading membrane specialists from around the world gave a total of 70 lectures covering desalination, reclamation & resource recovery, molecular separation, membrane fouling, gas separation, pre-treatment, industrial & bioprocess application and membrane monitoring. The Dutch representative at this conference was Dr. Emile Cornelissen, senior researcher at KWR, who presented his research on controlling Reverse Osmosis (RO) fouling after minimal pre-treatment. His main conclusion was that the 1-step RO scenario was approximately 20% lower in costs than the Ultrafiltration (UF) – RO scenario. Air/water cleaning is effective to control clogging, while lowering flux values results in less membrane fouling.
