The present invention provides a complex that is capable of eluting minerals beneficial to the human body and adjusting the contents of the minerals according to their health functions, and a method for producing the same.

Specifically, the present invention provides a composite filter including: a filter impregnated with halite; a filter impregnated with calcite; and a filter impregnated with organic germanium-containing ore powder, wherein the filter impregnated with halite, the filter impregnated with calcite, and the filter impregnated with organic germanium-containing ore powder are sequentially stacked.

A filter material that contains a non-woven fabric is provided. When the amount of deformation of the filter material is 10 mm, its three-point bending strength is 2.0 MPa or greater.

The technology disclosed herein relates to filter assemblies and methods of making filter assemblies. One filter assembly has a first sheet of filter media having a first perimeter region and a second sheet of filter media having a second perimeter region. The first perimeter region and the second perimeter region are bonded in a rim region. A plurality of adsorbent beads are disposed between the first sheet of filter media and the second sheet of filter media, and a substantial portion of the plurality of adsorbent beads are unbonded. Other embodiments are also described.

An improved impression wheel for use within respiratory face mask manufacturing machines that includes a first, second, and third series of spaced helicoidal teeth shaped and adapted to more efficiently and securely interconnect respective layers of respiratory face masks.

A system and method for laminating filter media can include applying an adhesive to a layer of the filter media and curing the adhesive. A multilayer filter assembly can include a first and a second layer laminated together using an inorganic adhesive.

There is disclosed a collector for machine fluids, comprising a mat having a perimeter wall upstanding therefrom, the mat and/or the wall comprising oleophilic material and the wall being water-permeable, so that water falling into the collector within the perimeter wall can escape therefrom, while the machine fluids are retained by said oleophilic material and wherein the collector comprises at least one composite component for machine fluid retention comprising at least three layers wherein at least one layer comprises activated carbon and wherein this layer is secured within the composite between two layers of porous material mechanically bonded to each other, preferably via needle punching, through the activated carbon layer. The collector has high efficiency in removing PAHs and other aromatics from oil/fuel contaminated water.

Woven polymeric fabrics or materials with antimicrobial additives suitable for example for use in connection with diatomaceous earth pool filters, monofilament pool cartridge filters, and trampoline mats are disclosed. Examples of the woven polymeric fabric of the present invention includes a composition having a polymer and at least one antimicrobial additive. Methods of composing and weaving antimicrobial polymeric materials are also disclosed.

The inventive subject matter disclosed herein includes multiple novel filter media made of activated rice husks, as well as filtration systems and methods for removing contaminants from an aqueous solution, such as wastewater produced as a byproduct of various industrial processes, including mining, oil and gas exploration and extraction, farming, manufacturing, and the like.

A first container for delivery of a fluid by way of a filtering device to a fermenting vessel, the fermenting vessel being connected to a fluid storage container, the first container, the fermenting vessel and the storage container being arranged in a substantially vertical stack.

The present invention relates to the field of water treatment/metal recovery and to materials/devices useful in such processes. Specifically the invention provides for composite materials comprising amyloid fibrils; activated carbon; optionally a support material; whereby said amyloid fibrils and said activated carbon are in intimate contact. The invention further provides for the treatment of water using such composite materials.
