Current commercial polymer membranes have shown high performance and durability in water treatment, converting poor quality waters to higher quality suitable for drinking, agriculture and recycling. However, to extend the treatment into more challenging water sources containing abrasive particles, micro and ultrafiltration membranes with enhanced physical durability are highly desirable. This r...
THE behaviours of protein solutions when filtered through membranes of graded porosities under different conditions of PH and dispersion medium have been further studied in the case of haemocyanin (Helix pomatia), edestin and egg albumin. The particle sizes of these proteins in dilute solution have been determined by Svedberg and his co-workers by the method of ultracentrifugal analysis, the re...
In the framework of understanding the transport mechanism that governs the filtration of NO3- solution through a γ-Al2O3 membrane with a nominal pore size of 5 nm at low ultrafiltration, a series of various types of nitrate solutions and operating conditions were investigated. The effect of filtration parameters such as pH, applied pressure and NO3- concentration on the selectivity and permeabi...
