Development of Asymmetric Low Pressure Reverse Osmosis-Surfactants Membrane: Effect of Surfactant Types and Concentration

Abstract: The effect of surfactants that are cationic (Cetyl trimethylammonium bromide (CTAB)), anionic (Sodium Dodecyl Sulphate (SDS)) and non-ionic (Triton X-100) on performance, morphologies and molecular orientation of Polysulfone (PSF) low pressure reverse osmosis (LPRO) membrane were addressed. The experimental data showed that the increasing of 0.5 wt% in surfactant concentration produced higher pure water permeation (PWP) and flux. At 2.5 wt% of SDS, the LPRO membranes achieved the highest PWP of about  64.42 L/… Show more

“…Polyvinylidene fluoride/polyether glycol ultrafiltration membranes are also subjects of surface modification with surfactants. Using dual surfactants in the PVDF membranes improved the performance properties (flux and retention [3]) similarly to that of polysulfone membranes [1].…”

“…By the surface modification of polysulfone RO membranes by surfactants (either cationic, anionic or nonionic) performance of the membranes can be increased via modified morphologies and molecular orientation. Thus reverse osmosis can be carried out at lower pressure than usually used [1]. Surface modification is a frequent technique to create new membranes, thus cellulose acetate membranes (which are known as the oldest types of artificial membranes) can act as novel membranes after their surface modification with nano-particles.…”

“…The solution was stirred until it became homogeneous and then ultrasound was applied to the solution for 1 hour. Sulaiman et al [19]. Have used a nano ZnO composite membrane PSF that has been left for 1 day to remove air bubbles trapped in the solution due to stirring.…”

“…The solution was cast on a glass plate with a membrane thickness of 0.1 mm, and then the polymer is immersed into the coagulation site. In this study, a thin layer of the membrane was then soaked with water for 24 hours to separate the solvent trapped in the membrane matrix [19]. Membrane sheets were dried at room temperature for 24 hours [20].…”

“…3 Membrane-based seawater desalination and wastewater reuse are widely considered as promising solutions to augment water supply and alleviate water scarcity. 4,5 Now membrane processes are an efficient and reliable way to treat water and they have become better functioning and more cost effective than they were a few years ago. Reverse osmosis (RO) is one of established process and the leading technology for the desalination process of saline water which purify water by separating the dissolved solids from feed stream resulting in permeate and reject stream for a wide range of applications in domestic as well as industrial applications.…”
