“…However, both techniques have disadvantages; for example, activated carbon filtration is effective but expensive since it requires frequent regeneration [6]. Membrane technology processes, such as ultrafiltration, reverse osmosis and nanofiltration, have increasingly been used for pesticide and micropollutant removal in recent years [4,6,[8][9][10][11][12]. Considering that the molecular weights of almost all pesticides range from 200 to 400 Da [3], nanofiltration membranes are potentially useful for their removal.…”

A B S T R A C TThe solution-diffusion model was used to predict the behaviour of four nanofiltration membranes, two were made of polyamide and the other two were made of polypiperazineamide (DL and DK), when used for the removal of atrazine from aqueous solutions. The mass transfer model applied is very simple and its linearization facilitates rapid calculation of the relevant parameters. The two main parameters, permeate concentration and volumetric permeate flux, are obtained from three different coefficients: water permeability, A w , solute permeability, B s , and osmotic pressure coefficients, W. Good agreement between the experimental and the predicted atrazine concentrations was obtained for the NF-99, DL and DK membranes when the concentration was low. However, only the NF-99 membrane provided accurate values for the two main parameters in the whole range of concentrations studied, which suggests that the solution-diffusion model can only be applied to this membrane.

“…Nowadays, the technologies that have shown more favorable results for recovering desirable compounds from the brines have been membrane processes. This can be combined with adsorption processes using active carbon or ion exchange resins (Bódalo et al 2008). The rejection of total suspended solids, dissolved COD and phenolic compounds in UF process treating olive mill wastewater (OMW) and table olive wastewaters was investigated by El-Abbassi (El-Abbassi et al 2014).…”

“…Our research group has studied the removal of some typical organic compounds such as phenol and atrazine using NF and RO membranes [27][28][29]. The performance of three RO membranes (two of polyamide and one of polyether sulfone) to remove aniline from aqueous solutions was also studied [2].…”

The behavior of different reverse osmosis membranes, namely, HR98PP, SEPA-MS05, and DESAL-3B, was compared with the one predicted by a solution-diffusion model. This model assumes that the membrane has a homogeneous, nonporous surface layer and uses two main parameters, permeate concentration C p and volumetric permeate flux Q p , to characterize the membrane system. In order to calculate these parameters, the theoretical values of water and solute permeability constants, A w and B s , and the osmotic pressure coefficient, W, were initially determined. Using the software Sigma Plot V 10.0, accurate values of W, Q p , and C p were only obtained for the DESAL-3B membrane, i.e., the selected solutiondiffusion model can be applied to this membrane.
