Ceramic nanofiltration membranes: Rejection of salts and NOM at high ionic strength and modification of pore size by atomic layer deposition

Natural Organic Matter (NOM) is always present in the drinking water sources such as rivers, lakes and reservoirs. It causes several problems, including the unfavourable colour and odour of water, formation of disinfectant by-products and harmful microbial growth. In drinking water treatment, anion exchange (anion-IEX) is used for NOM removal....

Application of Atomic Layer Deposition on Ceramic Nanofiltration Membrane

Pressure driven membranes have become increasingly popular in removal of natural organic matter (NOM). With the purpose to tailor pore size of membrane to remove NOM effectively, atomic layer deposition (ALD) was applied on the ceramic nanofiltration (NF) membrane with a pore size of 1.3 nm. Ceramic membranes were chosen as the substrate...
