A method and apparatus for treating human waste by solidification. The method performed by the disclosed embodiment comprises receiving the waste in a toilet or receptacle, liquidizing the waste with a macerating pump, adding to the liquidized waste a solidification agent, mixing the liquidized waste and the solidification agent, and transferring the mixture of waste and solidification agent to a disposable container. The disposable container can be discarded through conventional solid waste handling procedures or discarded in sanitary landfills. The disclosed apparatus introduces a quantity of solidification chemicals into a liquidized waste provided from a holding tank of a recirculating toilet, and directs the mixture of waste and solidification agent into the disposable container.
Method For Chemically Solidifying And Encapsulating Hazardous Wastes In One Continuous Operation
A method of treating aqueous liquid and semi-liquid wastes to render them fit for ultimate disposal in a sedentary mass, by admixing with the waste a solidification agent, encapsulating the admixture before solidification in an elongate, pliable, tubular membrane, sealing the ends of the membrane, and allowing the admixture to set to a sedentary mass.
A method for treating aqueous liquid and semi-liquid wastes by solidification comprising the steps of mixing with the waste a dry water-reactive solidification agent comprising cement, a dry water absorbent material, and a powdered alkali metal silicate in a quantity sufficient to convert the mixture into a chemically and physically stable solid end product substantially insoluble in water and which contains no substantially free-standing water, and allowing the mixture to set to a sedentary mass. Additive agents such as surfactants, fixatives, waterproofing agents, coloring agents, and the like are also disclosed as assisting in the solidification reaction by reacting with certain constituents in the waste.
Method For Rendering Hazardous Wastes Less Permeable And More Resistant To Leaching
A method for treating liquid and semi-liquid wastes to render them fit for ultimate disposal, by first determining the ionic charge of the waste counter ions. An appropriate suspension of emulsified asphalt particles is then selected having an opposite particle charge to the ionic charge of the waste counter ions. The waste is then mixed with the selected suspension of emulsified asphalt particles at ambient temperature in an amount sufficient to react with the waste counter ions and coalesce into a hydrophobic mass.
Method For Improving The Quality Of Contaminated Waste Water

Assignee:
Chemfix Inc. - Pittsburgh PA
International Classification:
C02B 120
US Classification:
210 45
Abstract:
An aqueous solution of an alkali metal silicate and a silicate setting agent containing polyvalent metal ions is mixed with waste material to convert the mixture into a consolidated stable earth-like material substantially insoluble in water. The material is pulverized and mixed with polluted waste water, with the mixture being maintained long enough for the pulverized material to react with pollutants in the waste water to reduce or remove them, following which the suspended solids in the water are separated from it, leaving the water improved in quality; that is, water that is materially less contaminated than before treatment.
Controlled Gel Time For Solidification Of Multi-Phased Wastes
A method of controlling the gelling time during the solidification of multi-phased liquid and semi-liquid wastes comprising admixing the waste with cement, a powdered alkali metal silicate and a liquid alkali metal silicate.
Composition And Method For Immobilizing Organic Compounds In Hazardous Wastes And Soils

International Classification:
B09B 300
US Classification:
588252
Abstract:
The organic chemical waste content of contaminated materials such as soils and debris is immobilized by mixing such wastes with an agent consisting of a mixture of particulate rubber and biogenic amorphous silica. Where the semi-volatile content of the waste is known to predominate a greater portion of particulate rubber is advantageous and where such waste is known to be entirely semi-volatile organic material such agent advantageously consists essentially or comprises particulate rubber. Conversely, where the organic content of such wastes is predominately volatile organic material a greater portion of biogenic amorphous silica should be employed and where such organic waste is known to be entirely volatile organic such additive is advantageously biogenic amorphous silica.
hit hard. Jesse Conner, president of the labor union that represents city firefighters, said that as of Sunday, 113 firefighters had either tested positive for the coronavirus and were in a state-mandated isolation or had been exposed to the virus and were isolating while they waited on test results.

191 San Diego Fire-Rescue personnel decline COVID-19 vaccine so far
Jesse Conner, president of San Diego City Firefighters IAFF Local 145, who was vaccinated at the same event as the chief, said the number of personnel who have declined the vaccine is higher than he expected. He called around to firefighters to gauge the reasons behind the reluctance.
