Aquaset II

Aquaset II is an extremely versatile powdered solidifier. A 200‑MESH screen will pass 80% to 85% of the Aquaset by weight. It is used with aqueous waste solutions that are high in dissolved solids (salty solutions). It also will solidify many water‑soluble or miscible organic compounds (such as glycols). Aquaset II also finds its greatest utility in the solidification of aqueous solutions extremely high in dissolved solids, such as neutralized acids and bases, and those organic liquids that are water soluble or miscible. Examples of organic liquids in this category would include alcohols, benzenes, glycols, and low molecular weight ketones. Mixtures of Aquaset II and Petroset II are ideal when the above liquids are present in combination with oils and/or greases. Use of Aquaset II requires power mixing equipment. It is often used in conjunction with Petroset and Petroset II. It is particularly useful in treating Mixed Wastes which contain both heavy metals and water‑miscible organic compounds. The end product is a firm, soft solid. The pH of the liquid waste shall be adjusted to be between 5 and 11 prior to testing and solidifying. With EDTA solutions, pH shall be adjusted to fall between 7.5 and 10.0.

Aquaset II is used to treat wastes at any temperature above that at which any liquid components of the raw waste are fluid, and below 60°C (140°F).
