Abstract: 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.

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.

Abstract: A filter for gravity-fed applications, having filter media with a hollow center, the filter being generally prone to a degradation or cessation in fluid flow due to air entrapment or air lock within the filter housing cavity, which develops during filtering. A diffuser element is introduced to pierce the entrapped air bubble, the diffuser element being an elongated structure connected to the filter housing top end cap and extending through the entrapped air bubble to the filter media.
