Hazardous Waste Treatment Agents

Liqui-Set is a water-activated, granular solidification/stabilization agent used for treatment of aqueous liquids containing small amounts of dissolved and suspended solids, detergents, chelating agents, resins, and up to 5% oils. Liqui-Set does not require stirring, and is utilized by simple addition to the aqueous liquid waste. Typically, 100 to 150 pounds of Liqui-Set are required to solidify 45 to 48 gallons of liquid waste in a 55-gallon drum.

Liqui-Bond is chemically similar to granular Liqui-Set, but instead is a finely-divided powder. Its application requires power mixing, either with an impeller (drum mixing) or a ribbon-blender or pugmill (continuous or bulk mixing). It thus can be used to treat wastes with high solids content, including heavy sludges. With the addition of water, dry solid wastes can be successfully treated to meet TCLP leach-resistance standards.

Liqui-Bond II is used with the same range of wastes for which Liqui-Bond is used. Unlike Liqui-Bond, Liqui-Bond II sets up to a hard matrix. Load‑bearing strengths over 5 tons per square foot (69 psi, or 48.8 metric tons per square meter) can be achieved. It sets up slower than Liqui-Bond.

Chem-Bond is a powdered solidification/stabilization agent used either alone or in combination with Liqui-Bond or Petro-Lock. Chem-Bond finds its greatest utility in the solidification/stabilization of aqueous solutions very high in dissolved solids, such as neutralized acids and bases, and those organic liquids that are water soluble or miscible. Example of organic liquids in this category include alcohols, glycols and low molecular weight ketones. Mixtures of Chem-Bond and Petro-Lock are ideal when the above liquids are present in combination with oils and/or greases. Use of Chem-Bond requires power mixing equipment. Chem-Bond can also be used to treat sludges and soils contaminated with metals and/or water soluble or miscible organics, since it can stabilize heavy metals.

Chem-Bond II is used with the same range of wastes for which Chem-Bond is used. Unlike Chem-Bond, Chem-Bond II sets up to a hard matrix. Load‑bearing strengths over 5 tons per square foot (69 psi, or 48.8 metric tons per square meter) can be achieved. It sets up slower than Chem-Bond.

Petro-Lock is a finely ground solidification/stabilization agent for organic compounds. It is used in the treatment of wastes some or all of whose liquid components are not water-miscible (such as oils). Treatment of wastes which have both water-miscible and water immiscible components is accomplished through the use of a combination of Petro-Lock with Liqui-Bond, or Petro-Lock with Chem-Bond.
