... by mill-site filtrations using a DSS-Labstak M20-filter. Retention, flux and fouling were analysed. Membranes were also characterised by measuring contact angles and pure water permeability. These data were used to explain the experimental results with effluents and to choose the possible membrane ...

... were blended into polyvinylidene fluoride (PVDF) casting solutions containing N,N-dimethylacetamide. Based on the advancing and the receding contact angle measurements, it was found that the SMM modified membranes exhibited higher surface hydrophobicity than the unmodified membranes. The effec ...

... different nanofiltration membranes were tested in the laboratory set-up. The observed retentions for NP and BPA ranged between 70% and 100%. The contact angle is an indicator for the hydrophobicity of a membrane, whose influence on the permeability and retention of NP was evident. Regarding th ...
Desalination 146 (2002)

Membrane surface characterization was studied by contact angles using both a goniometer and a tensiometer. It was checked that static and dynamic advancing contact angles of ultrafiltration membrane ...

We have developed a method for the calculation of contact angle of spherical particle in interaction with a bubble in the process of flotation. The balance of forces acting on the instantaneous TPC
