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.

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: The technology disclosed herein relates to hydrodynamic separator. The hydrodynamic separator can be configured to separate a liquid having dispersed particles having a diameter. The hydrodynamic separator has a substrate and a liquid channel at least partially defined by the substrate. The liquid channel is configured to receive a liquid within the channel. The liquid channel has an inlet and an outlet. The outlet has a first outlet branch and a second outlet branch. The liquid channel has an inner wall defining an inner radius around a central axis and an outer wall defining an outer radius around the central axis. The liquid channel has a liquid channel length along the inner wall from the inlet to the outlet. The liquid channel has a channel width between the inner wall and outer wall, where the channel has a tapered region where the channel width increases towards the outlet.
