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...

In this study, Cabernet Sauvignon red wine was subjected to reverse osmosis and nanofiltration processes at four different pressures (25, 35, 45, 55 bar) two temperature regimes (with without cooling). The aim obtain concentrates with a higher content of phenolic compounds antioxidant activity determine the influence membrane types (Alfa Laval RO98pHt M20 for NF nanofiltration) operating condit...

UV-induced grafting technique was used as a flexible method for surface modification of Polysulfone (PSf) ultrafiltration (UF) membranes in order to prepare hydrophilic nanofiltration (NF) membranes. Flat sheet Polysulfone (PSf) ultrafiltration membranes were prepared via phase inversion method. N-methylene-2-pyrrolidone (NMP) and polyethylene glycol (PEG) of three different molecular weights (...

A novel nanofiltration membrane bioreactor (NF-MBR) was constructed by integrating a loosely structured hollow fiber into an aerobic activated sludge system. In order to verify the feasibility of loose NF bioreactor, parallel experiments conventional ultrafiltration (UF-MBR) and NF-MBR were conducted investigate process performances, fouling characteristics. The showed relatively high permeabil...
