nanofiltration-based separation processes have found diverse applications in industrial and environmentalproblems recently, due to several advantages such as lower energy requirement and elevated flux ratescompared with their reverse osmosis (ro) counterparts. several attempts have been made for modellingnf-based separation processes ranging from rigorous space-charge approaches to simpler irre...

The direct utilisation of side streams from membrane processing and evaporation is great potential interest for dairies to reduce water consumption. In an analytical screening 89 industrially obtained streams, samples varied in pH conductivity broad ranges 4.22 7.56 0.001 0.949 Siemens per meter, respectively. Detailed compositional data the enabled assessment their applicability as diafiltrati...

Fouling of nanofiltration (NF) membranes is the most significant obstacle to the development of a sustainable and energy-efficient NF process. Colloidal fouling and performance decline in NF processes is complex due to the combination of cake formation and salt concentration polarization effects, which are influenced by the properties of the colloids and the membrane, the operating conditions o...

To overcome the limitations of polymers, such as trade-off relationship between water permeance and solute rejection, well difficulty functionalization, research on nanomaterials is being actively conducted. One representative graphene, which has a two-dimensional shape chemical tunability. Graphene usually used in form graphene oxide treatment field because it advantages high functionality its...

Liquid desiccant air conditioning (LDAC) is an emerging technology able to maintain optimal growing conditions in self-sustained greenhouses powered by solar energy. However, the regeneration of liquid (LD) a bottleneck LDAC. This study investigates six desalination technologies – membrane distillation (MD), reverse osmosis (RO), nanofiltration (NF), forward (FO), thermoresponsive (TR) solution...

Membrane technology has a significant role in textile wastewater treatment considering the modular design of membrane processes that enables to conceive complete scheme. The study presents comparative microfiltration (MF) (0.2 µm and 0.05 µm), ultrafiltration (UF), ozonation (0.1, 0.2 g/L ozone), ultraviolet (UV) irradiation titanium dioxide (TiO2) (0.05, 0.15, 0.3, 0.5 TiO2) zeolite adsorption...

Separation of monosaccharides and monovalent salts is important in the biorefinery food industry. Nanofiltration (NF) technology promising for this purpose but its poor selectivity still needs to be addressed. In work, separation by NF improved regulating surface charge pore size distribution polyamide membranes. The carboxyl groups on membrane are selectively activated N-(3-Dimethylaminopropyl...

We have combined a turbulent jet flow ozone contactor (TJC) with a membrane bioreactor (MBR) to establish a zero-discharge system in terms of excess sludge in the MBR. The TJC-MBR system was compared with the conventional MBR (Control-MBR) with respect to i) the size and zeta potential of the sludge particles, ii) the loosely bound extra-cellular polymeric substances (EPSs) and tightly bound EP...

A membrane bioreactor (MBR) combines biological treatment with the membrane separation technology. To improve the understanding of the MBR processes and know how, many researches were carried out suing the trial and error method and build the knowledge based on experiments. The problem with such an empirical research is that the results are difficult to generalize due to the complexity of the s...
