Micellar-enhanced ultrafiltration (MEUF) was studied to remove reactive dyes from aqueous solution. Two different types of reactive dyes, C.I Reactive Black 5 (RB5) and C.I Reactive Orange 16 (RO16) were tested. A cationic surfactant, cetylpyridinium chloride (CPC) was used for the MEUF and its effe

In this paper, the implications of the so-called optimized NF membrane properties on the economic assessment as well as the process performance of NF membrane system will be discussed. The predictive model for NF membranes such as the Donnan-steric-pore model has been used in conjunction with an eco

Pretreatment process is a significant factor in the success of desalination process. It plays a key role in enhancing the lifetime of RO membranes in desalination process. Microfiltration process is emerging as an alternative solution for desalination pretreatment process. The baffled microfiltratio

Thin film composite (TFC) co-polyamide membranes were modified by adding carboxyl group to the polypiperazinamide backbone. The sodium chloride, sodium sulphate, magnesium chloride and magnesium sulphate rejections were measured at various feed pressures for the modified and unmodified membranes. Th

Reverse osmosis performance for certain low molecular weight organic solutes in water, such as phenol and its derivatives, is markedly different from that of simple aqueous salt solutions. The unusual solute–membrane affinity reverse osmosis behaviour of phenol–water–cellulose acetate system has bee
