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.
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.
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.
