摘要： The present invention describes a filter medium and a method of filtering metals from liquids, such as waste water, in which the metals are filtered from the liquids and are chemically fixed in the resulting filter cake in a nonhazardous and nontoxic form so that they may be disposed of in nonhazardous landfills. When all or a portion of the metals are dissolved, they are first precipitated and then filtered and chemically fixed.

摘要： Disclosed is a combined flocculating and clarifying medium for flocculating and separating solid particles from waste water comprising a mixture of solid filtering or aggregating particles and a dry flocculating agent effective to flocculate the solid particles to form larger and heavier aggregates with the filtering or aggregating particles in the waste water and filtering or gravity separating the formed aggregate from the waste water. Preferably, the filtering and aggregating particles are silicious particles, such as rice hull ash, diatomaceous earth, and perlite. The flocculating and clarifying medium can be combustible or can chemically fix the aggregated solid particles in a silicious cement, which solid particles can include heavy metal particles in silicious cement.

摘要： A protective garment, including a double protective garment, for working in radioactive, nuclear, and/or toxic environments, wherein the main body has a rear surface and the rear surface comprises a reversible opening which is adapted to allow a SCBA (self-contained breathing apparatus) tank to be removed and replaced while the user continues to wear the protective garment. The reversible opening can be a zipper, including a double zipper. The protective garment is formed of a tri-laminate 30/30/30 water resistant barrier fabric. The garment can be incinerated so as to provide a disposable, one time use coverall particularly adapted for use in nuclear/radioactive environments. The coverall provides integrated elements for water resistance (i.e., splash resistant), breathable, comfortable contamination protection with a high volume of water vapor transfer which can mitigate worker heat stress. It is adapted for use with various types of breathing apparatuses, included external air lines, back-mounted SCBAs, and emergency breathing bottles or apparatuses. Air tanks and bottles are covered by the garment and thus do not need to be decontaminated. The garment also can include elements for use with air sampling devices and/or dosimetry equipment that are often worn by such workers.

摘要： Disclosed is a filter aid or medium and a method of filtering liquid wastes having good filtration, good flow rates through the filter area, and heat value of the resulting filter cake containing the filtered solids of at least 5000 Btu per pound of filter aid. Rubber particles in a mesh size range of from about 30 mesh to 325 mesh, alone or with up to about 70 % silicious particles, and preferably a wetting agent is used for the filtration.

摘要： In-Situ Formation of Soluble Silicates from Biogenetic Silica in Chemical Fixation/Solidification Treatment of Wastes Disclosed is the solidification and chemical fixation of liquid wastes using biogenetic primarily amorphous silica to the waste in the presence of a strong alkali in the waste which converts the biogenetic silica into a soluble silicate, and in the presence of a polyvalent metal ion in the waste which reacts with the soluble silicate to provide a cementitious product of the waste. In the event there is insufficient strong alkali present in the waste to convert the biogenetic amorphous silica to a soluble silicate, and insufficient polyvalent metal ion in the waste to harden and form a cementitious product, amounts of these components as necessary can be added along with the biogenetic silica to the waste. The resulting cementitious and chemically fixed waste can be left in place, for example to provide a land farm, or can be removed and broken up and used as a cover for land fills, various land applications, and farms, as well as other applications.
