Abstract
A process for the treatment of waste material is disclosed. The process includes the steps of combining waste material with a treatment composition to form crystal growth structures, and adsorbing the waste material within the crystal growth structures, thereby stabilizing the waste material. The treatment composition includes natural zeolite seed, crystalline quartz, aluminum trihydrate, sodium carbonate or sodium hydroxide, and optionally dolomitic calcium oxide or calcium oxide or dolomitic limestone, and potassium hydroxide or potassium carbonate.
Claims20
A process for waste treatment comprising the steps of:
- determining an amount of free, unbound water in a waste stream and hydrating waste material therein to form a slurry;
- mixing the slurry with a treatment composition containing natural zeolite seed, crystalline quartz, aluminum trihydrate, and a compound selected from the group consisting of sodium carbonate, sodium hydroxide, potassium carbonate, potassium hydroxide, and combinations thereof, to form a mixture containing natural zeolite crystals and synthetic zeolite crystals, thereby producing stabilized waste material.
A waste treatment process comprising the steps of:
- determining the amount of unbound water in waste material;
- hydrating the waste material to form a slurry;
- mixing the slurry with a treatment composition comprising natural zeolite seed selected from the group consisting of clinoptilolite, chabazite, heulandite, phillipsite, mordenite, and combinations thereof;
- crystalline quartz, aluminum trihydrate, a compound selected from the group consisting of sodium carbonate, sodium hydroxide, potassium carbonate, potassium hydroxide, and combinations thereof;
- at a temperature from about 70.degree. to 600.degree. Fahrenheit to form a treatment mixture containing natural zeolite crystals and synthetic zeolite crystals;
- and
- adsorbing contaminants from the treatment mixture within the natural zeolite crystals and synthetic zeolite crystals, thereby producing stabilized waste material.
