A cell capture, disruption, and extraction method includes a introducing a plurality of abrasives in a disruption chamber, which can include diamond powder, variably and multi dimensionally disbursed therein, and a pestle positioned in the disruption chamber. The method includes agitating the abrasives by moving the disruption chamber and/or pestle, agitation of the abrasives tearing cell structure in the solution to access its contents. A binding column or size exclusion column can be positioned downstream of the disruption chamber. Cell solution can first be introduced in the disruption chamber, the abrasives capturing the cells and allowing therethrough and purging the waste content, then breaking the cell content. The lysate can then bind to an extraction matrix downstream of the disruption chamber or it can be mixed in with the abrasives.

A media filter includes an inlet and a diffuser located axially below the inlet for distributing liquid entering the filter via the inlet over the media in the filter. The diffuser including one or more members extending generally orthogonal to the axis of the filter.

A novel fibrous membrane comprises at least one substrate layer comprising at least 80% by weight of microfibers that carry positively charged and/or negatively charged functional groups, and at least one layer of filtration material attached to the substrate layer, wherein the layer of filtration material comprises at least 80% by weight of nanofibers that carry negatively charged and/or positively charged functional groups. The fibrous membrane is able to remove or reduce the concentration of bacteria, viruses and heavy metals while maintaining relatively high water flow. A filter comprising the fibrous membrane and a method for manufacturing the fibrous membrane are also provided.

A combined heat and power microgrid system is provided that stores energy in the form of compressed air that can then be utilized as needed in the form of electricity. The compressed air may be generated with energy from multiple electrical energy sources, such as renewable energy sources. The energy stored as compressed air/heat is used to charge a battery by utilizing a pulley system and a barrel housing that transfers kinetic energy generated by the release of the compressed air to an array of piezoelectric generators that can produce electricity, which is stored in the second battery. In addition, water may be extracted from the compressed air storage tank. In this way, energy produced by the renewable sources can be accessed during periods of high need or low production and water may be collected.

A self-contained .[.portable.]. waste water evaporating apparatus is shown. A solar-operated submersible pump pumps waste water from just under the surface of a waste water pit, through a pair of automatic backflushing filters and out misters located around the bank of the waste water pit. At a predetermined pressure across the automatic backflushing filters, the automatic backflushing filters are reverse cycled, one at a time, to backflushing particles back into the waste water pit. Periodically, the misters are purged and/or cleaned to remove particles therefrom. In response to sunlight, solar panels provide DC voltage directly to the submersible pump. If pressure from the submersible pump gets excessive, a pressure relief valve removes the excess pressure.

A filter for producing a water composition containing silicic acid and hydrogen gas includes a carrier material and a silicon material supported on the carrier material. The filter has a diameter ranging from 50 m to 10 mm. A filter assembly, a filter device, and a water purification system containing the filter are also provided.

The present invention may provide a granular filtration system for filtering effluent water for agricultural operations. The system may comprise a granular media for filtering the effluent water, a vessel for holding the granular media, a filtration inlet, a filtration outlet, a backflush inlet, a backflush outlet, a plurality of filtration members, and a plurality of conduits, the conduits being in fluid communication with the plurality of filtration members, the filtration outlet, and the backflush inlet. The vessel may further comprise a plurality of access ports for accessing the interior of the vessel. The present system provides filtration members with sufficient size, shape, number, and placement to efficiently and evenly backflush the granular media, and a higher quality, hydrodynamically shaped tank which can be backflushed at a lower pressure, reducing water and energy use, leaks, and inconsistencies in the granular media.

A method for separating organic solvent(s) from an aqueous process stream including organic solvent(s), includes passing the aqueous stream including organic solvent(s) through a granular bed including glass granules, wherein at least 90% of said glass granules have a maximum particle diameter smaller than 1.0 mm.

Systems, devices, and techniques described herein relate to iron-based desalination of water. In some cases, an inflow of water including chlorine and sodium can be received. A plurality of iron nanoparticles may capture the chlorine and the sodium. The iron nanoparticles may at least partially include Zero Valent Iron (ZVI). An outflow of the water may be emitted. The chlorine and the sodium may be omitted from the outflow.

A piezoelectric deionization system uses a piezoid bed made up of multiple piezoids for deionization of a working fluid containing charged particles, ions, and/or ionic complexes. The working fluid may be salt water in various embodiments. A uniaxial compressive force is applied to the piezoid bed causing a piezoelectric effect in the piezoids, resulting in a piezoelectric field generated by each particle, which attracts charged particles, ions, and/or ionic complexes contained in the working fluid. The piezoid bed is contained in a closed chamber to which the uniaxial compressive force is applied. Monocrystalline quartz particles or another suitable piezoid, natural or synthetic, may be used. A fluid is used to purge the piezoid bed of charged particles, ions, and/or ionic complexes after the piezoid bed becomes saturated through use. The working fluid may be used to purge the piezoid.
