Trace ions rejection tunning in NF by selecting solution composition: Ion permeances estimation [PDF]
, 2017 Nanofiltration (NF) is suggested to selectively remove ionic species in aqueous process streams taking benefit of both membrane and aqueous solution composition. The importance of predicting and optimizing selective ion rejections by NF not only of major

Description of the biofouling phenomena affecting membranes by the boundary flux concept [PDF]
, 2016 Membrane fouling, showing up with a significant reduction of process productivity and membrane lifetime, is one of the main issues in membrane technologies and has been successfully described by the boundary flux concept. Although the concept was applied

Predicting Stationary Permeate Flux in the Ultrafiltration of Apple Juice
LWT - Food Science and Technology, 1996 Abstract Stationary permeate flux were studied in the hollow fibre ultrafiltration of apple juice. The effect of flow velocity ( Q =10, 12.5 and 15 L/min) and volume concentration ratio (VCR=1, 1.5, 2 and 5) was determined over the 0–1.6 kg/cm 2 range of transmembrane pressure.
