WebSep 1, 2024 · Results showed that the seeding of gypsum at dosage of 1 g L−1 effectively restricted the membrane scaling and wetting. Although the combination of seeding and heating showed better membrane scaling control performance, the energy consumption of the SMDC system increased by 4 times without considering heat recovery. WebNov 1, 2024 · In gypsum scaling MD tests, both thermodynamic and hydrodynamic effects provided by the FAS coating should be discussed. From a thermodynamic point of view, FAS coatings enhanced the hydrophobicity of the pristine membrane, which helps to reduce the liquid-solid contact area and thereby reduce the heterogeneous nucleation sites [ 10 ].
