Abstract: Some embodiments of the technology disclosed herein relate to a system having a hydrodynamic separator element defining an element inlet and an element outlet. The element outlet has a first element outlet and a second element outlet. The hydrodynamic separator element has a plurality of curved microfluidic channels in fluid communication. Each of the plurality of microfluidic channels are arranged to operate in parallel. Each microfluidic channel defines a channel inlet downstream of the element inlet and a channel outlet having a first channel outlet upstream of the first element outlet and a second channel outlet upstream of the second element outlet. A flow characteristic sensor is in sensing communication with the separator element. A controller is in data communication with the flow characteristic sensor, where the controller is configured to provide a first alert upon the flow characteristic being outside a first threshold.

Abstract: A separation assembly has a microfluidic separation element having a substrate layer. The microfluidic separation element defines an element inlet, a first element outlet, and a second element outlet. The first element outlet is defined by the substrate layer. A permeate draining layer abuts the substrate layer. The permeate draining layer is downstream of the first element outlet.
