PETROSET-H is used to solidify aqueous solutions with low to moderate levels of dissolved solids. PETROSETH is used with power mixing to treat sludges and particle suspensions. With the addition of small amounts of water, PETROSET-H can solidify dry solids. PETROSET-H is frequently used in combination with other Fluid Tech products such as AQUASET II and PETROSET II. PETROSET-H sets up to a hard matrix (load bearing strengths of over 5 tons per square foot or 69 pounds per square inch can be achieved).
