“…Thanks to research, air scouring for submerged hollow fiber MBRs represents only 20% of the energy required [ 5 ]. With significant reductions in the size of equipment, lower energy requirements, and low capital costs, membrane technology becomes an attractive solution in wastewater treatment [ 6 , 7 , 8 ].…”

“…NF membranes with a pore size of approximately 1 nm can effectively remove relatively smaller organic substances such as pharmaceuticals and personal care products (PPCPs), color, degradation products from BTSE, and dissolved organics, targeting dissolved compounds [ 11 ] with a molecular weight of about 300 Da. NF proves to be an efficient system capable of treating BTSE to produce water of desired quality for industrial, agricultural, and indirect potable reuse applications [ 8 , 10 ].…”

In this article, an extensive examination is provided on the possible uses of membranes and hybrid processes in wastewater treatment. While membrane technologies face certain constraints, such as membrane fouling and scaling, the incomplete elimination of emerging contaminants, elevated expenses, energy usage, and brine disposal, there are approaches that can address these challenges. Methods such as pretreating the feed water, utilizing hybrid membrane systems and hybrid dual-membrane systems, and employing other innovative membrane-based treatment techniques can enhance the efficacy of membrane processes and advance sustainability.

This study investigates the scale inhibition performance of a commercial polyacrylic acid-based (PAA) antiscalant used for drinking water production and its molecular weight fractions (≤ 500 Da, ≥ 500 Da). The investigated antiscalant is used to prevent sulfate and carbonate scaling in treatment of drinking water sources by reverse osmosis or nanofiltration (RO/NF). Based on two complementary tests involving determination of induction time in a batch test and rate of flux decline in a lab-scale RO/NF plant, concordant results were obtained, proving that the overall performance of commercial PAA was controlled almost entirely by the higher molecular weight fraction. The low molecular weight fraction, which is potentially more permeable through the NF/RO membrane, showed poor inhibition against both sulfate and carbonate scalants. Furthermore, measurements on the assimilable organic carbon (AOC) by flow cytometry reveals that the low molecular weight PAA fraction has low biological stability, as its potential transport into the permeate of a NF270 nanofiltration membrane was inferred by elevated AOC values in the NF-permeate. These results are crucial information for water utilities, plant engineering, regulatory bodies and public authorities with respect to the possible operation of RO/NF especially in drinking water production.
