Described are filtration elements for removing materials from a fluid. The filtration elements generally operate by inducing cavitation into a fluid passing through them, generating energy and removing unwanted materials from the fluid. The filtration elements can be used singularly or in combination with one another for a multiple level filtration system.

The disclosure provides for a lab-on-a-chip (LOC) device and a method of fabrication thereof. Additionally, a system and a method for point of care testing of multiple biomarkers such as glucose, cholesterol, creatinine, uric acid, and bilirubin is provided. The microfluidic assembly consists of three layers in which the top and the middle layers are made up of polydimethylsiloxane (PDMS) and the bottom layer with polyethylene terephthalate (PET). The device integrates screen printed non-enzymatic electrochemical sensors in the bottom layer for simultaneous detection of glucose, cholesterol, creatinine, uric acid, and bilirubin. A hand held potentiostat with readout enables readout for the point of care application of integrated sensing device. The device developed has potential to revamp healthcare by providing access to affordable technology for better management a diabetes and related complications at every door step.

A bubble generating device is disclosed which includes: a bubble generator including a tubular body, a liquid introduction port, a gas introduction port, and a discharge port; and a gas supply unit including a gas supply port, a pressurized gas being supplied to the bubble generator through the gas supply port, wherein the flow passage of the bubble generator extends substantially along a same axis, a plurality of reduced diameter portions each having an inner diameter reduced are provided along a direction along which the liquid flows, and gas-liquid mixing portions are provided downstream of the respective reduced diameter portions in a contiguous manner, each of the gas-liquid mixing portions having an inner diameter larger than a minimum inner diameter of each of the plurality of reduced diameter portions, and the gas introduction port of the bubble generator is formed of a plurality of through holes.

Disclosed herein are continuous flow systems having bifurcated fluidic flow mixers. The mixers operate, at least partially, by Dean vortexing. Accordingly, the mixers are referred to as Dean Vortex Bifurcating Mixers (DVBM). DVBMs utilize Dean vortexing and bifurcation of the fluidic channels that form the mixers to achieve the goal of optimized microfluidic mixing.

An apparatus for mixing fluids, with particular application in the mixing of air and water for facilitating aerobic biological reactions for breaking down organic material. The apparatus includes gas-lift pump effected recirculation through a mixing chamber (in which a toroidal vortex is established) into a reactor vessel having an upper agitation region and a lower separation region. An embodiment for use with compostable materials includes an assembly for handling settleable solids and maintaining suspension of buoyant materials; a foam suppression device and an overflow reservoir.

A system and method of the purification of drinking water, ethanol and alcohol beverages is based on the action of hydrodynamic cavitation processing of microbiological and chemical contaminants, micro particles and colloidal particles. The fluid flow moves at a high rate through a multi-stage cavitation device and filtration module to generate hydrodynamic cavitation features in the fluid flow. The cavitation features generate changes in the velocity, pressure, temperature, chemical composition and physical properties of the liquid. The cavitation features also prevent the deposition of contaminants upon and remove contaminants from the surface of the filter module, reduce the load on the filter elements and increase the life of the filter module.

Aspects of the went disclosure are directed to a mixing device having at least one gas-carrying gas duct, at least one injection device for injecting a liquid and at least one first guiding element positioned downstream of the at least one injection device and projecting into a gas flow in the at least one gas-carrying gas duct. The at least one gas-carrying gas duct having at least one bulge of a duct wall directly downstream of the at least one first guiding element.

A multimodal micromixer obstacle for intensification of mixing and performing the reaction in a continuous manner is disclosed herein. The micromixer 100 comprises of plurality of inlets, an outlet and a plurality of channels. The end channelsof the channels, have pluralityof converging sections having width, to depth ratio ranging 1:1 to 20:1. The intermediate channels have at least, one obstacle having non-circular shape. Each converging section is incomplete ellipse, prolate or oblate shaped having, angle of curvature in the range of 90 to 270. Axes of the inlets are coplanar and perpendicular to the channels. All the components of the micromixer are coplanar.
