Patent ID: 8349184

Claim:
Procedure for lowering the viscosity of a biosolids material, including: providing a mixing vessel, the biosolids material being present in the mixing vessel; the biosolids material in the mixing vessel has a viscosity of V1 centipoise; providing an amount-A of urea or urea ammonium nitrate (UAN); at least gently admixing the amount-A of urea or UAN in with the biosolids material, in the vessel, thereby creating a product-P; the product-P, thus created, has a viscosity of V2 centipoise; wherein the amount-A, and the manner of the mixing, are such that the viscosity V2 of the product-P is both: (a) about forty percent of V1 or lower; and (b) about 100,000 centipoise or lower.
