“…Recently, Sengur-Tasdemir et al investigated various HF NF membranes' performances during pilot-scale filtration tests of surface water from a lake reservoir in Turkey. The reinforced thin-film composite membrane showed the best results regarding water softening as a hardness removal of 57% was achieved [56]. A constant flux of 4.76 L•m −2 h −1 was reported over the testing duration of 150 h.…”

Hollow fiber nanofiltration (NF) membranes have gained increased attention in recent years, partly driven by the availability of alternatives to polyamide-based dense separation layers. Moreover, the global market for NF has been growing steadily in recent years and is expected to grow even faster. Compared to the traditional spiral-wound configuration, the hollow fiber geometry provides advantages such as low fouling tendencies and effective hydraulic cleaning possibilities. The alternatives to polyamide layers are typically chemically more stable and thus allow operation and cleaning at more extreme conditions. Therefore, these new NF membranes are of interest for use in a variety of applications. In this review, we provide an overview of the applications and emerging opportunities for these membranes. Next to municipal wastewater and drinking water processes, we have put special focus on industrial applications where hollow fiber NF membranes are employed under more strenuous conditions or used to recover specific resources or solutes.

“…The phase inversion method was used to produce all membranes, which had four different PVC ratios (11‐13‐15‐17 wt% PVC) 24 . First of all, the solvent (NMP) was stirred at 60°C and then 2 wt% MA was added into the solvent.…”

In this research, polyvinyl chloride (PVC) polymer was applied for the first time in the fabrication of braid-reinforced hollow fiber membranes for ultrafiltration applications. Different concentrations of PVC solutions were cast on tubular braids and coagulated by the phase inversion method in a pure water bath to produce membranes with various porosities and pore sizes. The characterizations such as scanning electron microscopy, overall porosity, contact angle and mean pore size were done to understand membrane morphology.

“…High-pressure NF and RO membranes can provide an alternative method for removing organic and inorganic matter. The NF process is already known for its capabilities in the removal of total organic carbon (TOC) in surface water treatment [ 56 ]. This process has been implemented in several drinking water industries [ 57 , 58 , 59 ].…”

Water is one of the main sources of life’s survival. It is mandatory to have good-quality water, especially for drinking. Many types of available filtration treatment can produce high-quality drinking water. As a result, it is intriguing to determine which treatment is the best. This paper provides a review of available filtration technology specifically for drinking water treatment, including both conventional and advanced treatments, while focusing on membrane filtration treatment. This review covers the concerns that usually exist in membrane filtration treatment, namely membrane fouling. Here, the parameters that influence fouling are identified. This paper also discusses the different ways to handle fouling, either based on prevention, prediction, or control automation. According to the findings, the most common treatment for fouling was prevention. However, this treatment required the use of chemical agents, which will eventually affect human health. The prediction process was usually used to circumvent the process of fouling development. Based on our reviews up to now, there are a limited number of researchers who study membrane fouling control based on automation. Frequently, the treatment method and control strategy are determined individually.
