Disclosed is a filter core water flow channel, comprising a filter core housing (1), the filter core housing (1) respectively comprising an upper area (1) and a lower area (12) in mutual communication according to high to low positions, the upper area (11) being provided with a front filter core (2), the lower area (12) being provided with a kernel filter core (3), the filter core housing (1) further being provided with a water inlet (5) and a water outlet (6), the water inlet (5) being in communication with the upper area (11) via the lower area (12) around the kernel filter core (3), water passing through the water inlet (5) and the lower area (12) surrounding the kernel filter core (3) and entering the upper area (11), and after filtering by the front filter core (2), water then flowing into the kernel filter core (3), and finally flowing out via the water outlet (6).

The present disclosure is directed to an immobilized media device and methods for making an immobilized media device. The present disclosure is also directed to methods for the separation of components of a media comprising filtering the media through an immobilized media device.

A filter element comprises a porous body. The porous body is made of bonded matter, including: at least one material for binding lead; and at least a binder having a Melt Flow Rate, MFR, of more than 1 g/10 min. The porous body has a Mean Flow Pore size, MFP, in a range of between 0.1 and 11 m.

A filter reinforcing material is disclosed that does not cause peeling or pleat adhesion at the time of pleating, is excellent in pleating, and has high stiffness. A filter reinforcing material includes a bonding layer comprising a thermal bonded nonwoven including thermal bondable short fibers, and a reinforcing layer comprising a nonwoven including high-melting fibers having a higher melting point than a melting point of the thermal bondable short fibers having the lowest melting point in the bonding layer by 30 C. or more. Further, the bonding layer preferably comprises two or more kinds of thermal bondable short fibers with a fineness difference of more than or equal to 5 dtex.

A treatment module including a housing having an input port and an output port; a plurality of treatment members, each treatment member having a skeleton and a mesh material provided over the skeleton, the mesh material being joined to the skeleton at one or more portions of the skeleton; and a layer of particles formed over a first side of the mesh material, the layer having pores of sufficient size to enable a fluid to flow through the layer.

A drinking water treatment system is disclosed. The system includes an ultraviolet (UV) light source and an adsorption medium positioned downstream of the UV light source. The UV light activates residual chlorine in water. The adsorption medium is configured to adsorb any remaining free chlorine from the water. Drinking water treatment systems are disclosed for point-of-use (POU) applications, such as tap-mounted countertop, under-counter, and/or commercial bottling applications, and for point-of-entry (POE).

The present invention concerns the field of refining metal melts or slags and provides in particular a reactive material based on calcium aluminate and carbon, its process of preparation and various methods for refining metal melts using the same.

A method is described for treating activated carbon configured to be included in a carbon block of a filter for a water purifier. The method includes: inserting the activated carbon into a chamber; injecting ozone generated from an ozone generator into the chamber, and applying pressure to the chamber; and modifying a surface of the activated carbon inserted into the chamber based on applying the pressure to the chamber that holds the ozone and the activated carbon.

Disclosed is a filter element from removing contaminants from water comprised of first filter media particles having a first particle size and second media particles having a second particle size and methods for making such a filter element. The first media particles are adhered to surfaces of the second media particles. A binder connects the second media particles with one another so that interstitial spaces are formed between second media particles. A portion of the smaller first filter media particles are positioned within the interstitial spaces. According to one embodiment of the disclosure water flows through the filter element at a flux greater than about 1.5 ml/min/cm.sup.2 has a pressure drop less than 20 psi.
