A saturator, configured for use in a water treating apparatus, includes a chamber, in which a first flow path through which first fluid flows is formed, and a plurality of porous membranes disposed in the first flow path, a second flow path formed within the plurality of porous membranes, through which second fluid flows. The first fluid is dissolved in the second fluid, or the second fluid is dissolved in the first fluid. Accordingly, a contact area between the first fluid and the second fluid is enlarged, and thus, a dissolving speed increases.

A UV reactor irradiates a flow of fluid with UV radiation. The reactor comprises: a fluid conduit defined by a heat conducting conduit body comprising one or more heat conducting walls for permitting a flow of fluid therethrough; a UV-LED operatively connected to a PCB and oriented for directing radiation into the fluid conduit. The PCB comprises a heat conducting substrate having a first surface. The conduit body is in thermal contact with the first surface of the heat conducting substrate. Heat is dissipated from the UV-LED via the heat conducting substrate, the thermal contact between the first surface of the heat conducting substrate and the heat conducting conduit body, and from the one or more heat conducting walls of the heat conducting conduit body to the fluid flowing through the fluid conduit.

A sediment filter system includes a series of segment layers each having a fibrous layer sandwiched between outer layers, wherein each of the series of segment layers includes different ratios of the material comprising the fibrous layer as compared to the material comprising the outer layers. The fibrous layer comprises a low-density material relative to the outer layers. The segment layers with higher compositions of outer layers include additional sheets of outer layers thereby decreasing the range of pore sizes.

A filter assembly includes an inlet end, a sediment filter having a sediment filter surface facing the inlet end and cylindrical filters. The sediment filter surface is orthogonal to each cylindrical filter surface. A first channel and a second channel may fluidly connect the sediment filter to the more cylindrical filters. The first channel can have a central axis that is orthogonal to a central axis to the more than one cylindrical filter. A central axis of the second channel may be in a direction along the length of the more than one cylindrical filter.

Described herein includes sample liquid purification apparatus, systems, and techniques of use. The purification apparatus generally can operate to reduce a temperature of a precursor liquid within a beverage machine or appliance. For example, a thermally conductive body can define a heat sink having a tortuous path for propagation of the precursor therethough, facilitating temperature reduction. The purification apparatus can further generally operate to sanitize or otherwise reduce a level of contaminants in the precursor liquid. For example, an energy source, such as a light emitting diode, can be arranged or integrated with the thermally conductive body to emit ultraviolet radiation toward the precursor liquid within the thermally conductive body.

In a method for treatment of waste water, a module (5) is used which includes a number of carrier elements (7) arranged in a sandwich structure and configured to be perfused a flow of waste water. The module (5) further has a number of partitions (8) arranged between carrier elements (7) and configured to direct the flow of waste water through the module (5). The module (5) may also be used in a system together with an air supplying device (20) and a waste water vessel. The air is supplied to the module (5) by the air supplying device (20).

A monitoring system is configured to detect a threshold amount of petroleum in a storm water-based fluid of an oil handling facility. For instance, the storm water-based fluid can be drained from a floating roof of a petroleum storage tank, a diked area, or a retention pond.

Embodiments of this disclosure provide a liquid treatment apparatus. The liquid treatment apparatus comprises: a housing which is of a cylindrical shape and comprises an accommodating space; an inlet for a liquid to flow into the accommodating space; an outlet for the liquid to flow out of the accommodating space; a treatment medium used for treating the liquid contacting the treatment medium; and a spiral flow-guiding device making the liquid in the accommodating space flow in a spiral direction around an axis of the cylindrical shape at least before contacting the treatment medium or in contacting the treatment medium. An advantage of this disclosure exists in by making the liquid in the liquid treatment apparatus flow in a spiral direction before contacting the treatment medium, natural energy in the liquid is increased, thereby improving a capability of the treatment medium in treating the liquid.
