Abstract
Flocculant compositions containing a cellulosic compound, a superabsorbant polymer, and a flocculant, are useful for preventing the formation of an aqueous phase during the shipping of fly ash slurries.
Claims22
A solid composition suitable for absorbing water and flocculating fine particles from a solids-containing slurry containing fine particles in suspension in an aqueous phase, comprising:
- a) a fibrous cellulosic component comprising at least one of wood particles or paper particles present in an amount of 50 to 90% by weight based on the weight of the solid composition;
- b) a superabsorbent polymer present in an amount of 5 weight percent or more based on the weight of the solid composition;
- and
- c) a flocculating agent.
