ПОПЕРЕДНЯ ОЦІНКА НОВОЇ КОНСТРУКЦІЇ СПЕЙСЕРА МЕМБРАННОГО МОДУЛЯ

In the current work, the results of the assessment of the effectiveness of the novel design of the spacer for the spiral wound membrane module using computational fluid dynamics methods were represented. The feature of the new design of the spacer is the shape of the filament, which has a triangle shape of cross-section. The results of the simulation have demonstrated that this shape of filament allowed for decrease the number of the stagnant zones in comparison with the conventional spacer design (filament with round cross-section). Also, in the considered range of conditions, a decrease of the pressure drop by 12-18% is observed in the channels with the novel design of spacer.
