Contact angle

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 perimeter in the radial direction could connect the central angle α and the contact angle θ in only on

Several nanofiltration and tight ultrafiltration membranes were tested 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 ex

Surface modifying macromolecules (SMMs) are oligomeric fluoropolymers synthesized by urethane chemistry and tailored with fluorinated endgroups. Two novel SMM formulations were blended into polyvinylidene fluoride (PVDF) casting solutions containing N,N-dimethylacetamide. Based on the advancing and

Endocrine disrupting compounds can affect hormone systems in organisms. However, conventional wastewater treatment plants are not able to remove these substances sufficiently before disposing effluent into the environment. Membrane technology, which is proving to be an effective barrier to these sub

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 membranes with water were in very good agreement. For glycerol and α-bromonaphthalene, dynamic advancing conta
