NOVELTY - Treating biosolids produced by biological wastewater treatment method, involves providing dewatered biosolids produced in a biological wastewater treatment method, directing the biosolids to a dryer, partially drying the biosolids in the dryer to where the dry solids content of the biosolids is approximately 50% or more, during first drying phase, directing the biosolids to a blender and blending nutrients into the partially dried biosolids, after the first drying phase, and drying the biosolids in a second drying phase in the dryer.    USE - The method and system are useful for treating biosolids produced by biological wastewater treatment method (all claimed).    ADVANTAGE - The method produces uniform and higher value dried biosolids product.    DETAILED DESCRIPTION - Method for treating biosolids produced by biological wastewater treatment method, involves (a) (i) providing dewatered biosolids produced in a biological wastewater treatment method, (ii) directing the biosolids to a dryer, (iii) partially drying the biosolids in the dryer to where the dry solids content of the biosolids is approximately 50% or more, during first drying phase, (iv) directing the biosolids to a blender and blending nutrients into the partially dried biosolids, after the first drying phase, and (v) drying the biosolids in a second drying phase in the dryer to where the dry solids content of the biosolids is greater than 90%, after blending nutrients into the biosolids, or (b) (i) providing dewatered biosolids produced in a biological wastewater treatment method, (ii) directing the biosolids to dryer, (iii) partially drying the biosolids in the dryer to where the dry solids content of the biosolids is at least 50%, during a first drying phase, (iv) directing the biosolids to a pelletizer and pelletizing the biosolids, after the first drying phase, and (v) drying the pelletized biosolids in a second drying phase in the dryer to where the dry solids content of the pelletized biosolids is greater than 90%, after pelletizing the biosolids. An INDEPENDENT CLAIM is included for system for drying and processing biosolids, which comprises (a) dryer, (b) first conveyor disposed in a first section of the dryer and operative to receive biosolids and to move the biosolids through the dryer, (c) second conveyor disposed in a second section of the dryer and operative to receive biosolids and move the biosolids through the dryer, and (d) blending machine or a pelletizing machine operatively disposed between the discharge end of the first conveyor and the inlet end of the second conveyor, where the first conveyor includes inlet end and discharge end, the second conveyor is spaced from the first conveyor and having an inlet end and discharge end, the blending or pelletizing machine operative to blend nutrients with the biosolids received from the first conveyor or operative to pelletize the biosolids, second conveyor is operative to receive the biosolids after the blending machine has blended nutrients into the biosolids or after the pelletizing machine has pelletized the biosolids, and the second conveyor is operative to move the biosolids through the dryer.
