This application relates to an oxygen infusion module for a system and method of treating wastewater wherein an oxygen infusion system is used to supersaturate wastewater before aerobic biological processes, wherein oxygen is transferred to the wastewater free of oxygen bubbles and achieves a reduction in power demand for the aeration process of wastewater.

A method for manufacturing a porous membrane includes: mixing silicon carbide powders and a coagulant to form a first mixture; adding a sintering aid to the first mixture to form a second mixture; compressing the second mixture; and sintering the compressed second mixture. More particularly, the coagulant is in an amount of 1% to 3% by weight of the silicon carbide powders and the sintering aid is in an amount of 10% by weight of the first mixture.

A filter element for filtering milk in a milk frother, comprising a plate-shaped porous main body, having a first side at which the milk can enter the porous main body, a second side at which the milk can exit from the porous main body, and a lateral side connecting the first and second sides, wherein the surface of the first side is less rough than the surface of the second side, and wherein the first side and the second side are different from one another.

Aspects of the present disclosure provide various apparatus and methods. In some embodiments, an apparatus is provided for mixing a gas with a liquid. The apparatus may include a pipe having two ends. The pipe may provide a main fluid path and may have an interior surface having a first groove. The apparatus may also include a helical vane disposed inside the pipe. The vane may have a first projecting tongue that engages the first groove. The apparatus may also include a gas injection port on the pipe adapted to inject gas into the fluid path upstream of the helical vane. In some embodiments, the helical vane may be a 3D printed component.

An apparatus for mixing fluids within a pipe is provided. In one embodiment, the apparatus includes a fluid mixing device with a pipe having a pipe wall and an axial bore for conveying fluids through the pipe. The fluid mixing device also includes a sleeve disposed about the pipe and a cavity provided between an exterior surface of the pipe and an interior surface of the sleeve. The cavity and the axial bore of the pipe are in fluid communication with one another via an opening through the pipe wall. Additional systems, devices, and methods are also disclosed.
