... resistance is discussed. After screening 17 diamines, N,N’-dimethyl-m-phenylenediamine (N,N’-DMMPD) was selected in the preparation of the reverse osmosis polyamide membrane. The membrane prepared from N,N’DMMPD and 1,3,5-benzenetricarbonyl trichloride (TMC) showed much higher chlorin ...

Site-specific raw seawater quality impact study on SWRO process for optimizing operation of the pressurized step
... site-specificity in the determination of seawater quality conditions is a crucial point for improving the overall energy efficiency of a seawater reverse osmosis (SWRO) process. To this end, field studies were carried out at 16 sampling sites along the shoreline in South Korea to investigate the... and microscopic contexts, respectively. As a result, the microscopic dynamic model revealed that concentration polarization in the vicinity of the membrane surface and permeate concentration are affected by the feed seawater concentration and pressure. Then, the application of Fujairah SWRO plan ...

... best operating performance of the RO process of desalination. Desalination 227 (2008) 295–305 Elimination of biological fouling in seawater reverse osmosis desalination plants Nobuya Fujiwaraa,b, Hideto Matsuyamaa* a Department of Chemical Science and Engineering, Kobe University, Rokkodai,... by chlorine injection were measured and quantified. Furthermore, actual demonstration of RO pilot tests using cellulose triacetate (CTA) RO membranes with chlorine resistance was performed in RO plants where bio-fouling actually occurred. By carrying out direct chlorine sterilization of the RO
