Ultrafiltration as an alternative membrane technology to obtain safe drinking water from surface water: 10 years of experience on the scope of the AQUAPOT project

Tertiary amine block copolymer containing ultrafiltration membrane with pH-dependent macromolecule sieving and Cr(VI) removal properties

“…As pH value increased, the form of tertiary amine groups changed accordingly from fully protonated (at lower pH), partially protonated (near pKa), to deprotonated (at higher pH). Meanwhile, the Cr(VI) existed primarily as salts of chromic acid (H 2 CrO 4 ) (pH ≤ 1.0), hydrogen chromate ion (HCrO 4 − ) (pH = 1.0-6.0) and chromate ion (CrO 4 2− ) (pH ≥ 7.0) [34].…”

“…Membrane-based separation technology has been widely used in environment protection, industrial applications, pharmaceutical manufacturing, drinking water supply and so on, because of its Desalination 355 (2015) 91-98 high efficiency, implementation easiness, and cost effectiveness [1][2][3][4]. Ultrafiltration (UF) is one of the most important membrane-based separation technologies.…”

The use of nanoparticles as alternative pore former for the production of more sustainable polyethersulfone ultrafiltration membranes

“…Therefore, a lot of effort is spent in the modification of these membranes. In the literature, three different approaches are described: (1) pre-modification of the polymer (before membrane synthesis) [7]; (2) the use of additives in the dope solution (during membrane synthesis) [8] and (3) post-modification of the membrane surface for example by surface grafting or thin film coating [9]. Because of the simplicity of the method and the lack of additional steps in the membrane synthesis procedure, the use of additives is the most attractive solution for membrane manufacturers.…”

“…Access to safe drinking water is one of the main challenges worldwide [1]. Therefore, the reuse of (waste)water becomes more and more important.…”

Activated carbon impregnation with ag and cu composed nanoparticles for escherichia coli contaminated water treatment

“…Approximately 25 infectious diseases are related to water quality, and these diseases can be caused by pathogenic microbiological agents such as bacteria, viruses, protozoa, etc. (e.g., cholera, typhoid, dysentery, infectious hepatitis, leptospirosis, giardiasis, and gastroenteritis) . Due to the complexities associated attempting to detect all possible pathogens in water sources, bacteria such Escherichia coli have been widely used to evaluate the microbiological quality of natural water and water for human consumption …”
