摘要： A filter composition effective in reacting with airborne or gaseous organic impurities, such as formaldehyde. The filter composition is formed from a filter substrate, such as for example, a fibrous web or extruded carbon block, treated with tris-(hydroxymethyl) aminomethane. The unexpected result of this combination is a longer lasting filter capable of adsorbing organic airborne impurities for a much longer period of time than an untreated filter media of the same type. The removal of formaldehyde is presented as an illustrious example.

摘要： An alumina-based adsorbent and method of making exhibiting high affinity and capacity towards fluoride ions and oxyanions of phosphorus and arsenic in a broad pH range and presence of large excess of competitive ions. Alumina based adsorbent is a mixed oxide of alumina existing in tetra-, penta-, and octahedral coordination at specific ratio, and oxides of polyvalent metals of elements titanium, zirconium, tin, cerium, lanthanum, iron, or combinations thereof. The alumina based adsorbent may be used for selective removal of fluoride ion and oxyanions of phosphorus and arsenic from drinking water, industrial streams and wastes, in medicine and food industry.

摘要： A sorption media with a high capacity to remove heavy metals, lead, and mercury, in particular when synthesized from a titanium source that contains sulfur, such as black liquor or titanyl sulfate (TiOSO4). The use of sulfur provides a higher than expected capacity for Pb and/or Hg. A Group 1 and/or Group 2 metal-titanosilicate is employed, having a Ti to Si molar ratio of 0.5-2, a pore volume of at least less than or equal to 0.25 cc/g.

摘要： A treatment solution and method for removing heavy metal contaminants and oxyanion contaminants from an aqueous solution by promoting the affinity of precipitating the contaminants. The method adjusts the pH and the ORP of the contaminated aqueous solution by applying FeCl2 and/or NaOH reducing agents, and using and applying a titania-based treatment solution of TiO(SO4), H2SO4, and FeSO4.

摘要： An underdrain filter or strainer for use with power generation and ion exchange facilities, such as, but not limited to, deep bed demineralizers used in nuclear power plants deep bed ion exchangers. The filter is fabricated from a sintered, stainless steel mesh or wire-cloth filter media having a pore structure with pore size ranging approximately from one micron to two hundred microns. The filter media is composed of a plurality of filter media layers including a perforated inner core bonded to at least one drainage wire mesh, a filtration wire mesh, and a protective wire mesh forming an outer diameter, the layers being diffusion bonded to form a single monolithic laminate.
