  • Patent number: 10449513
    Abstract: Nanoparticle-treated particle packs, such as sand beds, may effectively filter and purify liquids such as waste water. When tiny contaminant particles in waste water flow through the particle pack, the nanoparticles will capture and hold the tiny contaminant particles within the pack due to the nanoparticles' surface forces, including, but not necessarily limited to van der Waals and electrostatic forces. Coating agents may help apply the nanoparticles to the particle surfaces in the filter beds or packs.

  • Patent number: 9878289
    Abstract: A portable or personal water filtration apparatus comprising upstream and downstream removable reservoirs and a back-washable filter interposed therebetween. The back-washable filter comprises an upstream housing and a downstream housing, inside of which are fitted a membrane cartridge and a slidable plunger. The downstream housing is rotatable relative to the upstream housing between two or more positions, including, for example, an open flow position, a closed flow position, and a back-wash position. In the back-wash position, the downstream housing and plunger are axially extendable relative to the upstream housing and membrane cartridge in order to obtain a charge of clean water in the plunger that may then be forced backward through the filter by returning the plunger to its starting position. This dislodges accumulated debris from the membrane and reverses the slowing of flow observed through repeated use of the filter.

The pH is raised by addition of caustic soda and/or soda ash. In a vertical clarifier silo, the feed is gently mixed to cause dissolved solids to precipitate and agglomerate to form suspended flocculates. The clarifier includes an internal mixer surrounded by a cylindrical tube diffuser. Rotation of the mixer provides gentle dual circulation patterns within the clarifier that allow for flocculates of a predetermined size to settle from suspension. The clarifier may also include one or more vertical recirculation lines to recirculate some of the heavier flocculates at the bottom of the vessel into the mixer chamber to enhance precipitation via the seeding effect. The suspended flocculates are stripped from the feed water in a centrifugal separator. The clarifier silo may be trailer mounted for rapid deployment.

  • Patent number: 8696897
    Abstract: The gray water recycling system includes a first holding tank for filtering and storing gray water from a washer. The processed water passes through an inline filter to a second holding tank. The second holding tank includes a first float switch operatively associated with a pump that shuts off power to the pump when the second tank contains less than a predetermined amount of processed water. An outlet pipe inside the second tank includes another filter to clean the processed water as the water passes through the outlet pipe. A second float switch activates the pump to pump the processed water to a toilet tank when the toilet tank water drains below a predetermined level. A battery power unit is operatively connected to the pump, providing power for selective operation thereof.

  • Patent number: 8685335
    Abstract: A chemical release system. Implementations may utilize implementations of a first cartridge that include a body coupled with a cartridge head at a first end and coupled with an end plug at a second end where the cartridge head includes a through hole configured to engage with an annular flange in a main head. The body may have an internal cross section. The first cartridge may also include a flow restrictor plate disposed within the body between the first end and the second end where the flow restrictor plate is oriented substantially parallel to the cartridge head within the body, includes only one opening therethrough, and substantially conforms with the internal cross section of the body. The body may include one or more through holes in a side of the body located between the flow restrictor plate and the cartridge head.

  • Publication number: 20130341291
    Abstract: A membrane separation device is disclosed along with systems and methods employing the device in blood processing procedures. In one embodiment, a spinning membrane separator is provided in which at least two zones or regions are created in the gap between the membrane and the shell, such that mixing of the fluid between the two regions is inhibited by a radial rib associated with the membrane that decreases the gap between the membrane and the shell to define two fluid regions, the ridge isolating the fluid in the two regions to minimize mixing between the two. Automated systems and methods are disclosed for separating a unit of previously collected whole blood into components, such as concentrated red cells and plasma, for collecting red cells and plasma directly from a donor in a single pass, and for cell washing. Data management systems and methods and priming methods are also disclosed.
