Nanofiltration Membranes for Removal of Color and Pathogens in Small Public Drinking Water Sources

Nanomaterials for removal of waterborne pathogens

“…SWNTs and MWNTs have been reported to be excellent filter for virus adsorption and inactivation than other routine filters. Nanofiltration membrane technologies are even effective for pathogens such as Cryptosporidium oocytes that have been major concerns in some developed nations also (Anderson et al, 2011). Some of the advantage that lies in implying nanotechnology for water treatment includes point-of-use techniques, time economy, high efficiency, simple treatment methods, and space saving (Nassar, 2013, pp.…”

Nanomaterials: Removal processes and beneficial applications in treatment

“…A class of composite fibrous membranes developed for water purification by Sato et al (2011) has an appropriate pore size to sieve bacteria and a suitable static charge to adsorb viruses. Patterson et al (2012) installed pressure‐driven membrane systems for nanofiltration to remove bacteria and viruses in small public drinking water supplies. The nanofiltration membranes achieved 4.5‐log removal of viruses and > 6‐log removal of bacteria.…”

Groundwater treatment by ceramic membranes: pilot tests at the Commonwealth Games Village in Delhi, India

“…They are made from inorganic materials like alumina, zirconia oxides, titanium, recrystallized silicon carbide and other materials. Hashim et al (2017) and Baker (2012) found ceramic membranes to work in harsher environments as compared to polymeric membranes and that they can be treated with efficient cleaning procedures having good flux stability. Its use of a pressurized backflush and other advantages made it imperative to be used in drinking water treatment.…”
