Abstract
Embodiments of the present disclosure relate generally to dead-end filtration systems and, more particularly, to pulse-modulated periodic backflush systems and methods for clearing fouling layers in dead-end filtration systems. In some embodiments, a controller may control the flow of fluid in the system from cycling from a forward flow to a reverse flow. In some embodiments, the controller may cycle from forward to reverse flow based on a volumetric flow ratio. Embodiments of the present disclosure describe optimal volumetric flow ratios for optimizing the break of cake in a dead-end filtration system. Embodiments of the present disclosure describe optimal volumetric flow ratios for optimizing recovery percentages of targeted particles.
