“…NF membranes are appropriate for dairy applications due to the permeability for monovalent ions (40 to 90%) and the restriction of multivalent ions (5 to 20%), sugars, dyes and small organic molecules (TOUATI et al, 2018). As lactose is a carbohydrate, the value obtained indicates the possibility of using the permeate in the production of sports drinks in accordance with Brazilian legislation (BRASIL, 2010), which stipulates a maximum concentration of 8% carbohydrates for this type of drink.…”

“…The pH values differed significantly (p < 0,05) and were lower than that described for ultrafiltered milk permeate reported by Faedo et al (2013) (6,70). This difference may be related to the type of membrane used in the whey concentration process and the separation of specific ionic groups (TOUATI et al, 2018) as well as the type of coagulation used to obtain the whey. In the production of acid cheeses, demineralization of the mass occurs due mainly to the exiting of calcium form the casein complex to the whey, which is inherent to the process (temperature and pH) (FOX et al, 2004).…”

“…To add value, whey can be concentrated through membrane systems [ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO)], which are widely used for reuse of whey components by the dairy industry (ILTCHENCO et al, 2018). NF is used in desalination and wastewater treatment as well as the food and pharmaceutical industries (TOUATI et al, 2018;RODRIGUEZ et al, 2017;ZACHAROF et al, 2016;WOODS et al, 2016;ZHOU et al, 2015).…”

Whey derives from cheese production and is used either in its original form or concentrated in dairy drinks and food products. The whey concentration process generates permeate, which is composed of water and minerals. An alternative for the use of whey permeate is in beverage products. Then, it is important to evaluate its physicochemical properties and sensory aspects of sports drinks formulated with this waste. Different sodium concentrations (0,024, 0,030 and 0,40%) were tested and the intermediate concentration achieved the best results in terms of osmolality in accordance with the standard of current legislation. For the sensory analysis, different concentrations of lemon flavor (0,02, 0,04 and 0,06%) were used, all of which differed significantly (p<0,05) from the commercial sports drink, but the 0,02% concentration had the smallest difference (1,47). The present findings demonstrate the potential of use of whey permeate obtained from nanofiltration for the formulation of sports drinks.

“…It was found that blending NF permeate and RO permeate after NF pretreatment is a cost-effective option as the RO process is more expensive than NF, and only 50% of the NF permeate was treated by RO. Touati et al designed a UF-NF-RO hybrid process to produce isotonic solutions and drinking water from coastal well water [ 24 ]. The brine produced by NF was treated using RO to be used as drinking water.…”

A Hybrid NF-FO-RO Process for the Supply of Irrigation Water from Treated Wastewater: Simulation Study

et al. 2021

Municipal treated wastewater could be considered as a water source for food crop irrigation purposes. Enhancing the quality of treated wastewater to meet irrigation standards has become a necessary practice. Nanofiltration (NF) was used in the first stage to produce permeate at relatively low energy consumption. In the second stage, two membrane combinations were tested for additional water extraction from the brine generated by the NF process. The simulation results showed that using a hybrid forward osmosis (FO)–reverse osmosis (RO) system is more efficient than using the RO process alone for the further extraction of water from the brine generated by the NF process. The total specific energy consumption can be reduced by 27% after using FO as an intermediate process between NF and RO. In addition, the final permeate water quality produced using the hybrid FO-RO system was within the allowable standards for food crops irrigation.
