Process for Forming Porous Filter Media

Posted on by legna880

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

Filter and Filter Media for Removing Organic Acid from Water

Posted on by legna880

Disclosed is a filter media for removing contaminants such as organic acids from water. The filter media comprises porous particles. The particles have a total pore volume greater than about 0.4 cc/g. The pore volume is primarily or substantially comprised of epipores, that is, pores that are larger than about 5 nm. The filter media may also include a non-porous filter material and a binder. The filter media may be formed into a filter element, with the binder joining particles of the filter media together into a solid body. The percentage of the total pore volume provided by epipores is greater than about 40%. The filter reduces an initial concentration of an organic acid by greater than 80% at a flux greater than 0.76 ml/min/cm.sup.2.

Electrostatic removal… Continuation in Part

Posted on by legna880

Abstract

Electrostatic removal of colloidal, soluble and insoluble materials from a fluid- Continuation in Part

 

A filter that contains an adsorbent to remove the soluble portion of the contaminant, and then some form of electrostatic attraction additive. The electrostatic attraction additive would serve to pull the colloidal and particulate portion of the contaminant out of fluid, which could be held indefinitely, or be used to hold while the contaminant is allowed to solubilize and then be removed by the adsorbent. The electrostatic attraction additive could either be positively or negatively charged depending on the surface charge of the particulates that are in the fluid, and includes particles or fibers charged with charged polymers, zeolites, cation or anion exchange resin, powdered alumina, or nano-alumina.

Water Filtration System

Posted on by legna880

WATER FILTRATION SYSTEM
US Patent Application Number: 20190126174

 

Abstract

A water filtration system includes a raw water reservoir that holds raw water. The system also includes a gravity filtration assembly to remove particles from the water as it passes through from the raw water reservoir. The filter of the assembly includes immobilized filter media within an enclosure.

Reverse Flow Gravity Filter Cartridge

Posted on by legna880

US Publication Number: WO 2016033596 A1

ABSTRACT
A carafe filter cartridge for reverse flow applications where the filter housing and filter media top end cap directs unfiltered fluid into the filter media annular cavity, through the filter media sidewalls. And the filter media bottom end cap prohibits egress, filter fluid from exiting through the filter media end or the annular cavity. Filtered fluid is instead directed out through apertures in the filter housing sidewall. The optimum ratio of annular cavity and/or top end cap orifice area to the respective perimeter is determined to remove the risk of detrimental fluid flow due to air bubble generation.

Filter media for gravity filtration applications

Posted on by legna880

US Publication Number:  US 20150014240 A1

ABSTRACT
A gravity filter media fabricated from multiple spiral wound or pleated layers, where different layers are designed for specific contaminant removal process and the layers are combined into a single pack for ease of use. The layers or fiber sheets are chemically treated for contaminant removal, with different layers having different chemical treatments, or the layers are immobilized with particles of various sizes for use as low contact-time adsorbents, with different layers having different immobilized particles, or the pore structure is varied from one fiber sheet to another—one being a tight pore structure, and the other being a more open pore structure, or any combination thereof. When using immobilized particles, the immobilized particles can be chemically treated for the specific removal of targeted contaminants, and multi-layered for custom designed removal of specific contaminants.
