Effect of hydrophobicity degree on PVDF hollow fiber membranes for textile wastewater treatment using direct contact membrane distillation

The objectives of this study are to study the effect of hydrophobicity degree of polyvinylidene fluoride (PVDF) hollow fiber membranes blended with different types of additives i.e. ethylene glycol (EG) and polyvinylpyrrolidone (PVP) on textile wastewater application. The degree of hydrophobicity o...
